THE APPLICATION OF ACETATE PEELS IN LITHIC USEWEAR ANALYSIS

A technique for making acetate peels of tools using Triafol is outlined. A series of ‘blind tests’ is described where the suitability of this replica material for reproducing the details of usewear was tested. The advantages and disadvantages of the use of acetate peels are discussed with reference to examination of usewear traces.     

THE USE OF TEXTURAL PARAMETERS IN THE ANALYSIS OF CAVE SEDIMENTS

This paper considers the presentation of the results of the mechanical analysis of cave sediments, suggesting that the use of grain size parameter scatter diagrams is preferable to the older method of cumulative percentage frequency graphs. A sequence of samples was taken from an ideally-situated cave, the Badger Hole at Wookey, and first subjected to the standard soil analytical tests, followed by a detailed mechanical analysis. It is hoped that this preliminary work will encourage a more quantitative approach to granulometric analysis for archaeological purposes, leading eventually to the extraction of more precise environmental data from cave sediments.     

LITHIC RESOURCES IN THE EARLY PREHISTORY OF THE ALPS*

Rocks, which are ubiquitous in archaeological sites as chipped or polished tools, were important factors in the prehistoric Alpine economic system. Archaeometric characterization and identification of source areas open the path to a more detailed understanding of the production and diffusion mechanisms behind Alpine lithic industries. An overview of the situation from the eastern to the western Alps in the Mesolithic, the Neolithic and the Copper Age illustrates current debates and issues.     

THE USE OF SPECIFIC HEAT IN THE NON-DESTRUCTIVE ANALYSIS OF SILVER/COPPER ALLOY COINS

Using partly plastic apparatus, specific heats of coins have been found calorimetricly to an accuracy of ± 3% for most coins. For silver/copper alloys the specific heat varies approximately linearly with the weight percentage composition, so the latter can be calculated for coins of unknown composition.     

THE USE OF NON-DESTRUCTIVE ACTIVATION ANALYSIS AND PATTERN RECOGNITION IN THE STUDY OF FLINT ARTEFACTS

A method is described for the identification of the origin of flint artefacts. The method is based on the variation in the trace element concentrations for different origins. The trace element concentrations were determined by non-destructive neutron activation analysis. The identification was obtained from a pattern recognition analysis.     

THE USE OF IMAGE ANALYSIS TO DETERMINE YARN TWIST LEVEL IN ARCHAEOLOGICAL TEXTILES

An analysis of the structure of archaeological textiles can give an insight into different traditions, geographic origins or technologies associated with the textile production. An important parameter in this context is the level and direction of yarn twist. In this paper a new quantitative method of yarn twist measurement is described. Using image analysis techniques a measure of the mean twist level and the variation in twist can be determined. The technique is applied to a selection of woven woollen textiles from the first-century Roman fort at Vindolanda in northern England.     

ARCHAEOLOGICAL PETROLOGY AND THE ARCHAEOMETRY OF LITHIC MATERIALS*

For 50 years, archaeologists and physical scientists have been dating, determining the composition of and measuring stone tools, and reporting them in Archaeometry and many other journals. In Archaeometry specifically, the number of papers devoted to the analysis of lithic material has increased at least 30 times since 1958 and volume 1. This is a reflection not only of an increase in the number of scholars devoting their time to the archaeometry of stone, but also of increases in the quality and quantity of instrumental technology available to researchers in the field.     

NEGATIVE FACTORS IN THE USE OF THE BIOCLIMATIC RESOURCES OF THE APSHERON PENINSULA

The author raise several significant problems involved in plans to establish resort functions on the Apsheron Peninsula, which together with its major metropolitan areas (Baku and Sumgait), serves as a center for oil refining and petrochemical production based on significant offshore oil drilling in the Caspian Sea. Among these problems are the fact that part of the area of greatest resort/recreational potential (northern coast) is also the area of highest SC₂ concentrations (reflecting chemical production in Sumgait), and that another promising location (southern coast) exhibits high levels of NO₂ (largely attributed to automobile traffic and power generation in Baku) (translated by Andrew R. Bond).     

THE USE OF SHELL-TEMPERED POTTERY IN THE CADDO AREA OF THE SOUTHEASTERN UNITED STATES

Abstract

Freshwater mussel shell was used as a temper in the manufacture of ceramic vessels by potters in the Caddo area of the southeastern United States after ca. A.D. 1300. This was at least one or two centuries after it became the dominant temper used by aboriginal groups in much of the Eastern Woodlands but generally contemporaneous with shelltempered usage in parts of the Southern Plains. The introduction of shell temper was variable across the Caddo area, and in certain regions its use was negligible in ceramic vessel assemblages until the sixteenth and seventeenth centuries but then was rapidly adopted as the dominant temper employed in vessel manufacture, particularly for utility wares. In the traditional territory of the historic Hasinai Caddo in East Texas, shell temper did not appear in vessels until the early eighteenth century, and then only in minor amounts on presumed trade vessels.     

PRINCIPAL TRENDS AND PROSPECTS OF THE USE OF WATER RESOURCES IN THE USSR

The increasing demand on water in the Soviet Union and the problem of assuring water quality require the construction of long-term water-management balances by drainage basins. These balances, based on predicted demand and water availability, would suggest the need for water-management projects within basins and interbasin transfers. Water needs would be evaluated both in terms of water requirements by categories of users and in terms of water quality. The most crucial regional problems involve the increasing shortage of water in Central Asia (with the prospect of interbasin transfer from Siberia) and in southern regions of the European USSR (with the problem of diverting water southward from the northern runoff slope). The Caspian Sea is expected to require a supplementary inflow of 80 to 100 cubic kilometers a year by the end of the century if the decline of its waterlevel is to be arrested. But southward diversion of northern waters is not expected to add more than 50 to 70 km³ at best, with a possible saving of an additional 10 to 20 km³ through decline of evaporation from a reduced Caspian Sea surface. The preservation of conditions in the Sea of Azov, the Aral Sea and Lake Balkhash pose additional water problems. [The senior author died in October, 1974].
