THE CHLOR-ALKALI INDUSTRIES IN THE USSR

Spatial patterns in the production of chlor-alkali chemicals (soda ash, caustic soda, and chlorine) in the USSR are examined. The opening of large new salt deposits in the Volga region in the 1950s not only increased output of soda ash considerably, but also dramatically shifted production because of soda ash's raw material orientation. In contrast, because caustic-chlorine production tends to be market oriented, it was mainly the development of chlor-organic synthesis in the 1960s and 1970s that resulted in much greater spatial dispersion of production. Overall, the industry is now in a slow-growth phase, following the rapid gains made during the postwar period. Soda ash production is actually declining, while the wide array of applications for chlorine, especially chlorinated hydrocarbons, promises continued growth for the caustic-chlorine sector.

THE OLIVE IN THE PREHISTORIC AEGEAN: THE EVIDENCE FOR DOMESTICATION IN THE EARLY BRONZE AGE

Summary. In 1972 Colin Renfrew suggested that the rise of Mycenaean civilization may have been made possible by the development of a polycultural triad of wheat, vine and olive in the Early Bronze Age. A careful examination of the botanical and archaeological evidence for the domestication of the olive lends little support to this aspect of the thesis. The palynological evidence from various points in Greece is inconclusive, but for most areas it would seem to suggest that the intensive cultivation of olive began in the Late Bronze Age or even later.
No conclusive archaeological evidence for processing or storage of olive oil exists for any period in the Bronze Age. The question of when olive domestication took place must remain unanswered until more data are available from Early and Middle Bronze Age contexts and more conclusive botanical data have been collected.

PROVENANCE OF THE SANDSTONE USED IN THE CONSTRUCTION OF THE KHMER MONUMENTS IN THAILAND

We investigated the sandstone used in the construction of the Khmer monuments situated upon and around the Khorat Plateau in north‐east Thailand in order to clarify the provenance. The sandstones of the 22 investigated Khmer monuments can be classified into three groups. The sandstone of Group 1 is lithic and is derived mainly from the Khok Kruat Formation. This group includes the sandstone used at Phimai, Phnom Wan, Muang Khaek etc. The sandstone of Group 2 is siliceous and can be subdivided into three further groups. The sandstone of Group 2 is considered to have been derived from the Phu Phan, Phra Wihan or Sao Khua Formations. The sandstone used at Muang Tam, Phnom Rung, Sdok Kok Thom, Preah Vihear (Khao Phra Wihan), Narai Jaeng Waeng etc. belongs to Group 2. The sandstone of Group 3 is feldspathic and is correlated with the grey to yellowish‐brown sandstone that is commonly used in the Angkor monuments in Cambodia. This sandstone is used at Wat Phu and Hong Nang Sida in Laos. The above results reveal that the choice of sandstone used for the Khmer monuments, including the Angkor monuments, was dictated by the surrounding geology.

BASIC PROBLEMS IN THE STAGE-BY-STAGE DEVELOPMENT OF THE TRANSPORT NET IN THE ZONE OF THE BAIKAL-AMUR MAINLINE

The evolution of the transport net within the BAM zone is examined in terms of three development stages. The first stage will involve the construction of the initial framework of the future transport net; aside from the BAM itself, it is recommended that consideration be given to the construction of a permanent motor road instead of the temporary construction road now envisaged. The second stage, in the author's view, should include the start of an extension of the Little BAM northward toward Yakutsk, as well as an oil pipeline (the author does not agree with the view that the BAM would replace earlier plans for a Trans-Siberian pipeline). The third stage would include a gas pipeline from the Yakutian fields to the coast; it is recommended that the gas line follow the alignment of the new railroads. No specific time frame is attached to the proposed three development stages.     

THE PHYSICAL FACTOR IN THE SYSTEM OF CONDITIONS DETERMINING THE LOCATION OF INDUSTRIAL PRODUCTION IN THE USSR

The generally accepted view that material-intensive industries tend to gravitate toward raw-material sources is analyzed in the case of the USSR. Primary processing is found to gravitate toward raw-material sources mainly in underdeveloped parts of the country. In the developed zone (European USSR, Urals, Transcaucasia), a significant spatial gap has developed between primary processing activities and raw-material sources as the original local resources become depleted and the industry must draw increasingly on long-haul raw materials. Several industrial groups are distinguished in terms of the pull of resource sites. In view of the current trend toward greater concentration of production (for cost-benefit reasons) and the growing volumes of production per establishment, primary processing establishments are usually dependent on more than one resource site, and this also tends to increase the length of haul. At the same time, the distribution of fuels, energy and water resources is assuming greater significance and tends to pull such industries as iron and steel, nonferrous metals, pulp and paper as well as petroleum refining toward the eastern areas of the USSR. The controversy over the location of a new integrated iron and steel plant based on ore from the Kursk Magnetic Anomaly is recalled.

CHANGES IN THE STRUCTURE OF EVAPORATION IN THE ARAL SEA BASIN

An analysis of evaporation changes in the Central Asian plain in connection with the drop of the Aral Sea level beginning in 1961 shows that there has been a reduction in evaporation from stream valleys and deltas and an increase in evaporation from irrigated land and newly formed evaporating surfaces. These new entities are primarily the Arnasay depression (west of the Golodnaya Steppe irrigation district) and the Sarykamysh depression (west of the lower reaches of the Amudarya), which have become filled with spent irrigation water draining from the irrigated land. Another new source of evaporation associated with human activity are the lakes and wetlands formed along the Kara Kum Canal as a result of the filtration of canal water. It turns out, furthermore, that irrigation on sloping piedomon plains, such as those watered by the Kara Kum Canal, requires more water than in old irrigated alluvial plains because of the additional water needed to flush salt out of the soil and to fill subsoil cavities and raise the watertable.
