We analyzed the provenance and petrographic characteristics for the rock properties from stone-lined tomb and stone chamber tomb at the Dorim-ri site of the Baekje Kingdom, located in Cheonan. The two tombs consist of 10 kinds of rocks including gneiss, diorite, and andesite. The major rock type is gneiss (54.3%), which composes the main chamber walls of the tombs. Diorite (11.3%) and andesite (10.6%) also make up a large percentage of the rocks, tending to be used to fill the space between the main chamber walls. Thus, the stones appear to have been used according to their shape and the disposition of the site, respectively. Investigation of their provenance, confirmed their source area to be near the Ipjang Reservoir, about 1 km away from the site, and their procurement was probably conducted via a waterway. This result might serve as basic data regarding the material procurement system of ancient tomb culture and for preservation measures for archaeological sites.

Radioisotope x-ray fluorescence analysis was performed to determine normalized elemental intensities for pre-Columbian sherds and roller stamps from different archaeological sites in the Middle Orinoco region of Venezuela. These normalized intensities were used to construct three-component (Triangle) graphs separating the sherds into three groups based on their known origin. The three-component graphs were: (Zn, Sr, Zr), (Rb, Sr, Zr), and ( A, Sr, Zr), where A = Cu + Zn + Pb normalized intensities. The total precision was shown to be better than 5% absolute for all cases studied. It was concluded that two of the roller stamps found at one site were probably manufactured in a different source area. This lends support to the notion that the roller stamps were a trade item in late pre-Columbian times (1000–1400 A.D.). The method applied in this study using a 109Cd (2 mCi) source seems to be appropriate for provenance studies of archaeological ceramics where many samples are processed, because it has the inherent advantages of being simple, economical, and rapid.

Rock typing is one of the most important steps in reservoir modeling, and it’s the main task in reservoir characterization. In carbonate, the rock typing work that’s been performed during the last two decades had a little progress in term of providing reliable estimation of reservoir behavior. However, the development of Conjunction Rock Properties Convergence, CROPC, a carbonate rock typing concept that provided an important and easy solution to the carbonate rock typing gaps, has a major breakthrough, even though, CROPC methodology was developed to capture the single pore network through the conjunction of Lithology, permeability, capillary pressure and water saturation. Therefore, the need to identify more complex carbonate pore network had led to the initiation of developing the Carbonate Rock Type Matrix RocMat, which will be detailed in this paper, as part of a Master of Science research project. In this novel concept the carbonate rocks were classified into homogeneous, single pore network, and heterogeneous rocks, dual and triple pore network with the utilization of the effective petrophysical properties of permeability, capillary pressure, saturation, porosity and height above free water level, all were classified in a conjunction matrix that honors these properties and at the same time enables generating sub groups as down scaling and estimation for unseen groups with infinite rock complexity capturing, at the same time it enables the ease to lump the groups and generates upscale-groups that make it easier for utilization by the geologist and reservoir engineers to achieve the objective of better reservoir performance prediction, the work was performed and then tested in two carbonate offshore fields data. This RocMat was structured to be the ultimate catalog for carbonate rock types.

The present paper describes obsidian sources and compositional analysis performed on obsidian recovered from natural flows in the upper Maule River basin (central Chile). We compare the composition of this obsidian with that of obsidian artifacts recovered from selected archaeological sites both in the middle and lower valley of the Maule River and in the Argentinian provinces of Mendoza and Neuquén. The results indicate that the collected obsidian samples can be separated into six major groups. Most of the obsidian artifacts are assignable to a particular source area, but there still remain some unknown sources. We conclude that the Laguna del Maule source area was exploited from at least 50 A.D. onward and that the material was distributed to sites located more than 200 km from the source.

AbstractIn the last twenty years, obsidian artefacts have been found in important and often extensive karst cavities in Southern Italy: three located in Calabria (Grotta della Monaca, and Grotta del Tesauro, in Sant’Agata di Esaro, Cosenza; Grotta Pietra Sant’Angelo in San Lorenzo Bellizzi, Cosenza), one in Puglia (Grotta di Santa Barbara in Polignano a Mare, Bari) and another in Campania (Grotta di Polla, Salerno). All these sites, that have returned a total of 151 obsidian tools, were connected to human frequentation of the underground environments that occurred during the Holocene, which can be precisely located in the vast period between the Neolithic and the Eneolithic (6th–4th millennium BC). They are mainly blades and bladelets, but also burins together with scrapers and cores, generally of small dimensions. SEM-EDS and WD-XRF absolutely non-destructive analyses carried out on these items have shown that all samples have a source area in the obsidian outcrops of the island of Lipari (Messina, Italy). These data confirm that the Aeolian island of Lipari furnished the privileged obsidian extraction outcrops for most of the Neolithic and Eneolithic archaeological sites of Southern Italy.

This study aimed to analyze the raw material procurement system based on six components, the performance and the added value of the palm sago agro-industry in Natar subdistrict of South Lampung Regency. The research was a case study in which location was chosen purposively in four Sago Aren Agroindustries by considerating that there were only four agro-industries that were still actively producing sugar palm sago in that area. The reseach data collection was conducted in March - April 2018 and analyzed by qualitative and quantitative descriptive and added value analysis. The results showed that the six components of raw material procurement namely time, place, quality, organization, quantity, and price in Sago Aren of Adi Putra, Oblak, and Surahmat Agroindustries were appropriate because they have been in line with expectations. There was still a component of material procurement standards that have not been matched or did not in line with the expectation in Kartim Agroindustry namely quantity. Production performance in the Sago Aren Agroindustries could be classified as good, because four of the five indicators in production performance namely productivity, capacity, quality, and speed of delivery were appropriate, while indicators of flexibility in the four sago palm agroindustry was not optimal, and the four sago palm agroindustry was feasible because it provided positive added value. Key words: sagu aren, performance, value added

AbstractA total of 51 obsidian samples from archaeological sites in western Mexico (La Quemada, Totoate, Las Ventanas, Laguna San Marcos) and from the Tequila source area were analyzed chemically by direct-current plasma atomic emission spectrometry (DCP) and instrumental neutron activation analysis (INAA) in an effort to identify the sources of the archaeological obsidian by step-wise discriminant analysis of the data. Surprisingly, only 3 of the 39 archaeological samples (2 from Laguna San Marcos and 1 from Las Ventanas) could be correlated with a Volcán Tequila source (Teuchitlan). Four other groups of archaeological obsidian were recognized. The largest, Group Y, was found to be derived from the La Lobera source located near the Jalisco–Zacatecas border. This source accounted for 12% of La Quemada obsidian and a higher proportion for Las Ventanas and Totoate. Source locations for the remaining three groups could not be determined from the existing chemical data base. These results could indicate that a minimum of interaction took place between La Quemada and the Teuchitlan cultural tradition. It shows that one focus of La Quemada's trade endeavors was in the Río Bolaños/Tlaltenango valleys. This study also indicates that organized obsidian trade between the Mexican core and its outer periphery was probably not a factor between a.d. 400 and 800.

The concept of a natural morphogenic geoecosystem was used to model the vegetation in the GIS environment. The edaphic factors used in modeling included landform elements characteristics (slope and concavity/convexity) as well as the soil and the parent rock properties that define drainage. The climatic factors influencing the distribution of the vegetation embraced annual sums of precipitation and of active temperature. The information about the ecological interrelations between the factors and the vegetation was taken from the regional literature as well as from the field observations. Key words: Ukrainian Carpathians, potential natural vegetation, natural morphogenic geoecosystem.
