The Fore-Carpathians part of Svicha River valley partially covers Morshyn and Zalissia Uplands and Stryi-Zhydachiv depression. Within the Svicha and Sukil' river valleys, there are well-developed different-age terraces with thick stratified loess covers. The investigation of the last ones can help to define nomenclature and age of the terraces. The loess covers of the third (Kolodiiv) and the fourth (Mariampil) terraces, which are represented by Pidberezhzhia and Mizhrichchia sections accordingly, are characterised in detail in the article. Pidberezhzhia section represents a sequence of alluvial and covering deposits of the third (Kolodiiv) over-floodplain terrace of Svicha River, which is developed on its right bank. The terrace is stretched out in the form of a narrow (about 2 km) strip from the village Zarichchia to the village Novoselytsia. It is separated from the Svicha riverbed by the system of different-altitude floodplain levels and the first and second over-floodplain terraces. The boundaries between them are morphologically distinct, the exceeding of the surface of the Kolodiiv terrace above the water level in the riverbed of Svicha reaches 10 m or even more. Covering loess-soil series on the terrace has a capacity of more than 6 m and begins with the Horokhiv fossil soil complex. Mizhrichchia section represents the fourth (Mariampil) over-floodplain terrace, which to the north of Mizhrichchia village forms a scarp to the riverbed of the Svicha River, about 20 m in height. The terrace on this part of the valley of the river covers small areas and it is developed between the villages of Zarichchia and Mali Didushychi. Almost along its length, the terrace directly scarps to the riverbed. On the opposite side, where the rear seam is, it borders on the fifth (Galician) over-floodplain terrace, which forms a scarp about 10 m in height. Loess cover on the fourth terrace is up to 14 m thick. There are welldeveloped Dubno fossil soil (MIS 3) and Horokhiv fossil soil complex (MIS 5) and a thick sequence of hydromorphic deposits, which obviously correspond to the Korshiv fossil soil complex (MIS 7) in loesspaleosol series. The studied Pleistocene covers allow us to reliably identify Mariampil and Kolodiiv terraces of the Svicha River, as well as outline the nomenclature of the remaining terraces of the adjacent sections of the Zalissia and Morshyn Uplands and Stryi-Zhydachiv depression. Key words: river terrace, loess-soil covers, Dubno fossil soil, Horokhiv and Korshiv fossil soil complexes, Fore-Carpathians, Zalissia and Morshyn Uplands.

Key section Pidvolochysk is located in the quarry of the currently inactive brick factory. It represents the Upper and Middle Pleistocene loess-soil series as well as some fossil paleocryogenic forms of the Khmelnytsky Plateau of the Podolian Upland. The ice-wedge casts of the Final Pleistocene (Krasyliv) palaeocryogenic stage are presented here especially intensely. One of them is studied on the engineering-geological aspect. In particular, it has been defined, that the loess filler of ice-wedge cast, in contradistinction to loesses that contain it, is loose and subsiding. This is of great importance for the engineering-geological evaluation of the properties of loess-soil strata. Key section Pidvolochysk is well stratified. Two Upper Pleistocene loess horizons (MIS 2, 4) and the upper horizon of Middle Pleistocene loesses (MIS 6) are disclosed here. Besides loess horizons, Dubno fossil soil (MIS 3) and Horokhiv fossil soil complex (MIS 5), as well as delluvial-solifluctional stratum above Dubno, are developed here. The engineering-geological properties of the loess and palaeosol horizons, including their subsidence, have been studied in detail. Individual characteristics of distinct stratigraphic horizons are given. It can be used during the engineering-geological research in the areas of distribution of Pleistocene loess-soil series. Key words: loess-soil series, key section, Pleistocene, palaeocryogenesis, engineering-geological features, Podolian Upland.

New geological and geomorphological investigations carried out in different parts of the Fore-Carpathian region of the Dnister River basin gave an opportunity to distinguish at least four separate different-age levels (terraces) within the Loyeva level (sixth terrace): Torhanovychi, Dubrivka, Susidovychi and Biskovychi. In the Solonske section the alluvial and cover loess-soil sediments from the Lower to Upper Pleistocene of the total thickness of about 30 m are revealed. Loess-soil series of the investigated section represents a number of loess and palaeosol horizons from modern soil (MIS 1), which is developed on the Horokhiv fossil soil complex (MIS 5), to the soil with spot-medallions (MIS 17–19). The last one was formed above the permafrost and obviously can be correlated with one of the soils of fossil soil complex of Zahvizdia type. A very thick (almost 10-meter) stratum of deposits that, apparently, have a limnic origin is underlying this soil. Alluvial deposits, which are directly under the limnic stratum, are composed of the channel and flood-plain facies and represent one of the identified separate levels of the Loyeva level (the sixth over-floodplain terrace of the Dnister River). In Solonske section two levels of the development of palaeocryogenic structures like spot-medallions are revealed (above the Lutsk fossil soil (MIS 9) and over one of the soils of fossil soil complex of Zahvizdia type). Undoubtedly, under the conditions of the proper further investigations of the section, Solonske can become a key point for Pleistocene not only for Fore-Carpathians. It will be important in determining the time of the formation of different-age levels of the Loyeva level. Key words: loess-soil series, alluvium, terrace, palaeocryogenesis, spot-medallions, Pleistocene, Loyeva level, Dnister, Fore-Carpathians.

The Tuinier Farm (41HP237), R. A. Watkins (41HP238), and Anglin (41HP240) sites are 16th to 17th century Caddo sites in the modern-day Post Oak Savannah of Northeast Texas. All three of the sites are located on Stouts Creek, in the eastern part of Hopkins County, Texas, a northward-flowing tributary to White Oak Creek in the Sulphur River basin; the modern channel of White Oak Creek lies ca. 15 km north of these sites. The Culpepper site (41HP1), a previously investigated mid-to late 17th century Caddo habitation and cemetery site, is about 2 km downstream. Small areas of tall-grass prairie lie to the north between the Stouts Creek sites and White Oak Creek, but the eastern extent of the larger White Oak and Sulphur prairies is approximately 15 km to the west and northwest. At the time of the Caddo occupation of the Stouts Creek sites, the climate was wetter and warmer than today, with significant mesic periods between A.D. 1477- 1524, A.D. 1539-1572, and A.D. 1603-1670. After A.D. 1670, the years from A.D. 1671 -1676 were relatively cool and dry. The more mesic periods had more equitable rainfall (adequate growing season rainfall) and this, combined with the warmer temperatures, led to an increased net productivity and carrying capacity of plants and animals in the Post Oak Savannah and Pineywoods that were settled by Titus phase populations. The Tuinier Farm site is the closest of the three sites to the headwaters of Stouts Creek. It is situated on a relatively flat and sandy upland ridge (460 feet amsl) about 1 km south of the Anglin site and just east of Stouts Creek. Anglin is on a sandy knoll (460 feet amsl) on an upland slope, also east of Stouts Creek. The third site, R. A. Watkins, is 1.2 km northwest of the Anglin site, also on an upland slope, but 200 m east of an intermittent tributary to Stouts Creek and 1 km from Stouts Creek.

AbstractOn at least three occasions (in 1633, 1634 and in 1635) Rembrandt visited the village of Sint Annaparochie in Het Bildt, where Saskia Uylenburgh lived from her fourteenth to her twentieth year. Biographies of the artist discuss only the days surrounding his marriage to Saskia in the Frisian village on 22 June 1634. The present report concerns Rembrandt's very first visit to Friesland, in 1633. His last visit to Het Bildt can be dated to 12 July 1635, when Saskia served as witness at the baptism of her young niece Antje van Loo, the fourth child of her sister Hiskia Uylenburgh, who was married to Gerrit van Loo, Het Bildt's municipal secretary. Saskia was presumably also present with Rembrandt at the baptism of Hiskia's third child, Sophia, on 2 June 1633. On 8 June he drew his famous portrait of Saskia in silverpoint on parchment. In 1853, A. Wassenbergh, pastor of Sint Annaparochie, published the details on the baptisms of the Van Loo children in the church register, including the presence of Titia Uylenburgh as witness in 1633. The importance of this document has been underestimated. Titia had married François Coopal of Flushing. He turns out to have registered at Franeker's university (a veritable Uylenburgh bastion), which explains his marriage around 1628 to Saskia's sister Titia. Titia and/or her husband were also witnesses at the baptism of every one of Rembrandt and Saskia's children. The document that indirectly establishes Rem-brandt's presence in Sint Annaparochie from 2 to 8 June 1633 is important. Rembrandt carried with him a kind of sketchbook, of which three parchment leaves have survived. One of them shows his engagement portrait of Saskia. The two other sheets, drawn on both sides, feature three landscapes. The stylistic connection between these sheets and the then uncommon subject matter, the landscape, has been noted by Schatborn, Schneider and Van de Wetering. The type of farm depicted is not Dutch but more likely Frisian. The date on the portrait, 8 June 1633, is a sound benchmark for the dating of the landscapes. The second sheet was later substantially cropped to turn the studies of the heads on the back into the main depiction. The third sheet, a view of some farm's still has its original format. The back of this sheet shows a panorama with a view of a village. Until recently a matt obscured the correspondence in format with Saskia's portrait. The panoramic landscape deserves closer consideration because it must have been done in Sint Annaparochie and could therefore depict the surroundings of the village. 'Het Bildt' is depicted on a map in Schotanus' 1664 Beschryvinge ... van Frieslandt. The situation in Rembrandt's drawing corresponds closely with the plan of the area as reproduced on Schotanus' map: from left to right we see Sint Annaparochie, a copse of trees to the north of what the map calls 'Vogel', and, probably, Vrouwenparochie, with summarily indicated spire. In June of 1633, in my opinion, Rembrandt drew the surroundings of the village in which he was to marry Saskia in July of 1634.

Boyanychi key section is one of the most complete, most famous and best studied sections of periglacial loess-soil series of Volhyn-Podillia. An almost complete history of the formation of rocks for the last 600 000 years is represented here. There is total thickness of loess-soil series approximately is 25 meters in this section. This key section is stratotype of Sokal fossil soil. Pseudomorphs after the structures of cellular ice of Boyanychi palaeocryogenesis stage were allocated here for the first time for Volhyn-Podillia and individual significance of this stage was substantiated as one of the most ancient in the Pleistocene. Boyanychi key section was studied by the use of practically all methods which apply for the investigation of Pleistocene deposits (in particular, micromorphological, palaeocryogenic, palaeomagnetic, engineering-geological, palaeontological, methods of absolute dating of deposits etc.). Detailed description of the section and the results of engineering-geological studies of rocks of all selected loess and palaeosoil horizons were done. Individual properties of selected stratigraphic horizons and their dependence on the paleogeographic conditions of sedimentation were displayed. Key words: loesses, fossil soils, palaeogeographical conditions, palaeocryogenesis, engineeringgeological features, subsidence, Volhynian Upland.

Description and detailed engineering-geological characteristic of rocks of the loess-soil series of one of the most complete loess section of Podolian Upland were given. Sharovechka key section represents the main loess and palaeosol horizons of Lower, Middle and Upper Pleistocene. There is total thickness of loess-soil series approximately is 25 meters in this section. Horokhiv and Korshiv fossil soil complexes, Lutsk and Sokal fossil soils, and lower horizon of Lower Pleistocene loesses can be key horizons for all territory of Volhyn-Podillia. The monoliths were taken from all stratigraphic horizons of this section with the purpose of investigation of engineering-geological features including subsidence. The analysis of the distribution of composition and features indexes in loess and palaeosol succession demonstrates a significant difference between their certain horizons caused by peculiarities of paleogeographic conditions of their formation and diagenetic transformation. It was also deduced that the degree of contrast of parameters of composition and features of loess and palaeosol horizons in comparison with key loess sections of Volhynian Upland was much lower. Probably this was caused by the higher total content of clay in soils of certain stratigraphic horizons and by the direct overlay of different types of fossil soils at each other. Key words: loess, loess-soil series, key section, fossil soil, engineering-geological features.

At environs of the village Dovhe in Ivano-Frankivs’k region (oblast) the fourth, fifth and sixth terraces of the Dnister River are well developed. They occur in the close vicinity to each other and are fully exposed. The authors published sections of the V and VI terraces earlier. In the present paper the description of the IV terrace is given. All the high terraces of the Dnister River from environs of Dovhe show the geological substrate below the alluvial cover. The section over the substrate parts is composed of the gravelly-to-pebbly channel alluvial deposits, sand and clay deposits of the alluvial plain, and covering subaerial loess and paleosoil deposits of the various thicknesses. In the fourth terrace, the complete section of the first and the second phases of the Korshiv paleosoil are exposed, with the entire thickness equal 3.6 m. Therefore, the ancient Korshiv paleosoil complex in the Dovhe section can be the stratotype section for the Forecarpathians. Key words: terrace, alluvium, subaerial cover, loess-soil series, buried soils, soil complexes, paleolit.

8 iron daggers of the advanced stage of the Prokhorov culture (III–II centuries BC), found in different years in the vicinity of the village of Tolbazy located in the forest-steppe of the Southern Urals (Republic of Bashkortostan, Aurgazinsky district) are published. It is shown that according to physical and geographical data, this area (about 15  15 km) is allocated to a single microdistrict located at the crest of the Bielsko-Urshak watershed, which has a width of more than 50 km at this point. The territory of the microdistrict is elevated (100 meters or more from the foot of elevation, 250 meters above sea level on average), it abounds with small lakes and springs on the top, with the sources of small watercourses on the slopes and it is surrounded by rivers on all sides. Most of the findings were made on the plateau or at the sources of small watercourses, some of them - in river valleys. It is concluded that this area can be considered as a separate honey cell, “nomadic parish” or summer dwelling complex, which is typical for the settlement system of early nomads to the north of the hills of Obshchiy Syrt. The nearest known honey cells are located at a distance of 5–12 km from Tolbazinsky district and the number of finds of bladed weapons of the mid-late I Millennium BC varies from 3–4 to 25 pieces. It is also shown that in the III–II centuries BC, the development of bladed weapons (swords and daggers with a straight cross quillion and a crescent-shaped pommel) among the nomads followed the line of standardization of earlier forms of the Southern Urals, the assimilation of individual innovations and imitation of samples with a ring-shaped pommel representing foreign culture for the region.
