A supracrustal sequence of biotite gneisses, light coloured garnet-biotite gneisses (metasediments) and metabasite rocks is bounded to the north-west and south-east by basement rocks of biotite (± hornblende) gneisses and metabasites. The supracrustal sequence lies in the core of a major F3 synform. Metabasite horizons are used as marker horizons to elucidate the structure of the area. Hornblende-granulite subfacies metamorphism accompanied the F3 folding; later retrograde metamorphism only affected the rocks along master joints and thrusts. Structural analysis of the basement rocks indicates at least two folding phases older than the F3 folding of the supracrustal sequence; the supracrustals also show minor folds of a fourth phase.

The programme of field investigations in the north of the Ivisartoq region begun in 1981 by Chadwick & Crewe (1982) was continued in 1982. Julia Park began mapping the Taserssuaq granodiorite, its host rocks and the Ataneq fault in the north-west. Dur team was joined by D. Bellur, Geological Survey of India, nominally as an assistant. In this report we present only summary notes of new findings relevant to the interpretation of the geometry and chronology of this segment of the Archaean crust in southern West Greenland. We use the established terminology for the Archaean rocks of the Godthåbsfjord region.

Abstract In this paper, we investigate the interplay between the morphosyntactic class of adjectives, the semantics of property concepts, and the function of noun modification in Tabaq, a Kordofan Nubian language (Nilo-Saharan phylum) spoken in the north-west of the Nuba Mountains in Sudan. Tabaq has a small class of adjectives containing few semantic types, and playing only a limited role with respect to the core function of adjectives: the modification of nouns. By contrast, a large number of descriptive modifiers is derived from two other word classes, verbs and nouns, and this paper describes the different ways of coding property concepts in Tabaq.

Little is necessary in terms of an introduction, since Amarna is one of the best-known settlements of ancient Egypt. The city was founded by pharaoh Amenhotep IV, known from his fifth regal year as Akhenaten, on his move away from Thebes and Memphis to found a new religious and administrative capital city. Akhenaten reigned approximately between 1348 and 1331 BC, and his principal wife was Nefertiti. Akhenaten’s direct successor appears to have been a figure named Smenkhare (or Ankhkheperure) who was married to Akhenaten’s daughter Meritaten. Like Nefertiti, Smenkhare/Ankhkheperure held the throne name Nefernefruaten. For this reason it is uncertain whether this individual was Nefertiti, who may have reigned for some years after the death of Akhenaten, possibly even with a brief co-regency, or whether this was a son or younger brother of the latter. The rule of Smenkhare/Ankhkheperure was short, and he or she was eventually succeeded by Tutankhamun. The core city of Amarna was erected on a relatively flat desert plain surrounded by cliffs on the east bank of the Nile, in Middle Egypt, approximately 60km south of the modern city of Minia, surrounded by the villages et- Till to the north and el-Hagg Qandil to the south. The site was defined by at least sixteen boundary stelae, three of which actually stand on the western bank, past the edge of the modern cultivation. In total, the city measures 12.5km north–south on the east bank between stelae X and J, and c.8.2km west–east between the projected line between stelae X and J and stela S to the far east, which also indicates approximately the longitude of the royal tomb. The distance between stelae J and F, to the far south-west, measures c.20km, and between stelae X and A, to the far north-west 19.2km. The core city, which is the part of the settlement examined in this section, was erected along the Nile, on the east bank, and it is defined by the ‘Royal Road’, a major thoroughfare running through the entire core city north–south.

It is not too much to describe the Ṣaffārids of S‚stān as an archetypal military dynasty. In the later years of the third/ninth century, their empire covered the greater part of the non-Arab eastern Islamic world. In the west, Ya'qūb. al-Laith's army was only halted at Dair al-'Āqūl, 50 miles from Baghdad; in the north, Ya'qūb and his brother 'Arm campaigned in the Caspian coastlands against the local 'Alids, and 'Amr made serious attempts to extend his power into Khwārazm and Transoxania; in the east, the two brothers pushed forward the frontiers of the Dār al-Islām into the pagan borderlands of what are now eastern Afghanistan and the North-West Frontier region of West Pakistan; and in the south, Ṣaffārid authority was acknowledged even across the persion Gulf in ‘Umān. This impressive achievement was the work of two soldiers of genius, Ya'qūub and 'Amr, and lasted for little more than a quarter of a century. It began to crumble when in 287/900 the Sāmānid Amīr Ismā'īl b. Aḥmad defeated arid captured ‘Amr b. al-Laith, and 11 years later, the core of the empire, Sīstān itself, was in Sāmānid hands. Yet such was the effect in Sīstān of the Ṣaffārid brothers’ achievement, and the stimulus to local pride and feeling which resulted from it, that the Ṣaffārids returned to power there in a very short time. For several more centuries they endured and survived successive waves of invaders of Sīstān—the Ghaznavids, the Seljūqs, the Mongols—and persisted down to the establishment of the Ṣafavid state in Persia.

AbstractThis article outlines the history of a people known as ‘Nubi’ or ‘Nubians’, northern Ugandan Muslims who were closely associated with Idi Amin's rule, and a group to which he himself belonged. They were supposed to be the descendants of former slave soldiers from southern Sudan, who in the late 1880s at the time of the Mahdi's Islamic uprising came into what is now Uganda under the command of a German officer named Emin Pasha. In reality, the identity became an elective one, open to Muslim males from the northern Uganda/southern Sudan borderlands, as well as descendants of the original soldiers. These soldiers, taken on by Frederick Lugard of the Imperial British East Africa Company, formed the core of the forces used to carve out much of Britain's East African Empire. From the days of Emin Pasha to those of Idi Amin, some Nubi men were identified by a marking of three vertical lines on the face – the ‘One-Elevens’. Although since Amin's overthrow many Muslims from the north of the country prefer to identify themselves as members of local Ugandan ethnic groups rather than as ‘Nubis’, aspects of Nubi identity live on among Ugandan rebel groups, as well as in cyberspace.

Обосновано выделение орогенного Северо-Западно-Корякского вулканического пояса. В методологии авторской глыбово-клавишной структуры литосферы определён на границе регионального прогиба и северной активной окраины Корякского микроконтинента механизм образования вулканогенов пояса. На пересечении поперечными межглыбовыми глубинными разломами литосферы границы регионального прогиба и северной окраины микроконтинента образовались локальные впадины вулканогенов. В них в эпоху олигоценовой тектоно-магматической активизации внедрились породы гранитно-метаморфического слоя коры, в которых образовались рудные столбы с золотом, ртутью, ураганным серебром, сопутствующими месторождениями  олова в породах фундамента. Обосновано выделение олово-золото-серебряных рудных районов вулканогенов пояса. Простирание пояса в пределы и Чукотки дает основание определить Северо-Западно-Корякскую металлогеническую зону. We managed to reveal the North-Western-Koryak orogenic volcanic belt. Using the authors'methodology of block and key structure of lithosphere at the boundary of the regional downfold and the northern active margin of the continent we defined the mechanism of the belt volcanogenes formation. The local regional downfolds were formed at the intersection of the transverse intra-block deep faults of regional downfold lithospheric boundary and the Koryak microcontinent's northern margin. During Oligocene tectonic-magmatic activity rocks from the crustal granitic-metamorphic layer with ore columns of gold, mercury, hurricane silver, associated with Sn deposits in basement rocks were introduced in them. The allocation of the tin-gold-silver ore regions in volcanogenic belts is proved. The trend of the belt within the margins and Chukotka gives the basis to determine the North-West Koryak metallogenic zone.

The valley of the Tochi River is an outlying corner of the British Empire in India forming a portion of Waziristan, the boundary of which was delineated in 1894–5 by an Anglo-Afghan Commission from the Afghan provinces of Khost on the north and Birmul on the west. Mr. F. H. Smith, of the Geological Survey of India, accompanied this Commission as geologist, and his observations “On the Geology of the Tochi Valley” were published in 1895 in the “Records of the Geological Survey of India” (vol. xxxviii, pt. 3, pp. 106–110, pl. iii). On p. 109 he says:—“The range of hills between Idak and Mirán Shah is formed by an anticlinal ridge which approximately strikes north and south, and which is composed of these lower eocene beds. In the core of the anticlinal a considerable thickness of massive dark grey limestone is exposed, in which I could find no fossil remains; the age of this limestone is therefore doubtful, and there is no evidence of any kind to show whether it belongs to the lowest tertiary or upper mesozoic age.”

Rainsborough is 1 mile South of Charlton village, in the parish of Newbottle, S. Northants, 20 miles North of Oxford, (SP 526348). The camp lies atc. 480′ OD, and the area enclosed isc. 6·25 acres.It lies on the edge of a plateau: the approaches to it are flat on the north-east, east, south and south-west, but a gentle slope to the north, north-west and west gives it a wide view across the Cherwell valley, towards Madmarston and Tadmarton (see map, fig. 1 and also pl. XXV). The defences are bivallate: the inner bank stands to 10 feet above the interior, and there is a drop of about 15 feet from the crest into the inner ditch; the second bank is very much lowered by ploughing, but still reaches a height of about 4 feet on the south side, where a hedge line has protected it; the outer ditch is nowhere visible on the surface, except on the west, when it carries a higher growth of weeds. The defences are covered with turf: the inner bank has also trees, bushes and the stumps of large beeches felledc. 1950. The bank is riddled with tree roots, and the sandy character of the core has attracted rabbits: recent attempts to dig and smoke out the warrens have slightly damaged the profile of the bank. A small dry stone wall is visible part way up the outer slope of the inner bank in several places.

Hareøen is an island north-west of Disko in western Greenland. It has the form of a plateau, whose highest point - 512 metres - is found near the south coast. Like the neighbouring parts of Nugssuaq and Disko, Hareøen consists chiefly of Tertiary basaltic lavas. The island first attracted attention on account of the presence of interbasaltic, coal-bearing sediments on the north-east coast. These were already examined by Giesecke in 1811 (Giesecke, 1910) and later among others by Steenstrup (1874) and B.E. Koch (1959). A petrographie investigation of the basalts was first undertaken by Holmes (1919), who described loose fragments rich in K2O. Lavas from the south coast, colleeted and analysed by Pedersen (1970), also have a high content of potash. V. Miinther in the years 1948-49 untertook geological mapping of the island, on which the present investigation is supported (Miinther, in press).

Detailed mapping of the north-west quadrant of the 1: 100 000 scale Isukasia geological map sheet was begun in 1981 (fig. 16). The area was previously visited during the 1977 helicopter reconnaissance mapping programme (Allaart et al., 1978) and from this work the stratigraphy was known only in the broadest of terms. The 1981 work has shown that the area is comprised of five principallithostratigraphic units, listed in Table 3.
