across the strata in the southern section are similar to those of the Mesozoic strata along the coast of North Jiangsu. The northern section (Late Creta- ceous) consists of gray to dark gray mudstone with siltstone, sandstone, and carbonate beds; the Lower Cretaceous consists of interbedded brownish-red mudstone and light brownish-gray siltstone and sandstone. The deposits appear to be mainly lacus- trine and may be a new frontier for oil/gas prospecting. Comprehensive Res. Brigade of Mar.

carbon resources in Chinese waters.] Mar. Geol. Quat. Geol., 6(4): 120pp; 13 papers. (In Chinese, English abstracts.)

A collection of papers focusing on the hydrocarbon potential, exploration, and development of the Chinese offshore includes several papers treating basins on the continental margins, descriptions of the Lower Tertiary of the Bohai Sea, the Cretaceous of the South Huanghai Sea, the reservoirs of the Beibu Gulf Basin, Cenozoic sedimentary basins, the role of Tertiary transgressions, lacustrine sediments, and biogenetic reef studies. An outline of oil and gas exploration and development trends and a chronicle of oil and gas prospecting are also presented. 0abf)

of hydrocarbon resources in China seas. Mar. Geol. Quat. Geol., 6(4): 1-8. (In Chinese, English abstract.)

China's seas possess abundant petroleum potential. In the past 25 years, geological prospecting has located six major sedimentary basins and discovered hydrocarbon seeps and commercial oil and gas flows. Three areas of research--basins (in the light of new geological theory), traps (based on an analysis of depositional environments), and accumulating deposits (including their porosity and permeabili-

ty)---should be investigated using geophysical and geological methods and a combination of offshore profile and well data. Bur. of Petrol. Geol. and Mar. Geol., Ministry of Geol. and Mineral Resour., People's Republic of China.

and gas resources of the nonsocialist countries of the world. Int. Geol. Rev., 28(7):765-769.

Oil and gas reserve data as reported by western sources are reviewed, summarized and re-estimated by methods employed by Soviet geologists. Then, the estimates are differentiated by production costs, and discussed in light of locale and the non-socialist world economy. (Gross oil reserves in the non- socialist world are estimated to be 1.2 trillion tons, of which 473 billion tons are technically, if not economically, extractable.) All-Union Res.

While plate tectonics has not led directly to the discovery of specific oil fields, the concept has helped to explain why certain types of sedimentary basin in the world are more suitable than others as sites of oil and gas generation and containment, and provides a framework for future exploration.
