试论地质大市场的构成及其发展建议

地质行业需要一个包括矿业市场在内的更广泛的地质大市场，地质大市场由地质项目市场、地质大市场由地质项目市场、地质资本市场、地质劳务市场和地质成果市场四部分组成，并初步论述了这四个市场。提出在地质大市场建设初期应采取两降低两抬高的原则，最大限度地增加有效需求，通过市场择优淘劣，确保成果质量，使地质大市场得以良性发展。     

地质信息系统分类及其相互关系

自然界的地质体都显示组分、组构和物性三方面的特征。组成地质信息系统的这三大部分，相至之间具有紧密的外在和内在联系，构成地质科学研究不可缺少的三大信息支柱。本文强调地质体及其地质信息系统作为一个系统整体的不可分割性。地学工作者应尽量系统地、全面地去收集三大类相互联系的地质研究信息，只有当人们系统掌握了这三方面的地质信息，并运用它们之间的内在关系把它们综合起来，才能恢复地质体的全貌，认识地质体的本质属

U.S.G.5. II Revisited*

Based on the most recent compilation of analytical data, a new set of “usable values” is calculated for six of the best known silicate rock reference samples produced by the U.S. Geological Survey. The latest version of the “best laboratories” method is described and results are compared with other recently published values.     

Deinocephalians of the U.S.S.R.

The deinocephalian pelvic girdle, of general pelycosaurian structure, is useful in systematic diagnosis. In primitive Russian deinocephalians, two contrasting pelvic patterns are recognized, one light, thin-walled, narrow, and of V-shaped cross-section, and the other massive, thick-walled, wide, and of U-shaped cross-section. The former is characteristic of two families of lightly- built, mobile land carnivores, the Eotitanosuchidae and the Brithopodidae. The Eotitanosuchidae are more primitive and pelycosaur-like, while the Brithopodidae show more variation, and specializations of large size, shallower acetabulum (related to mobility?), and re-enforcement of a weak pubic symphysis by additional processes. The massive type of pelvis characterizes large, heavily built herbivorous animals of the family Estemmenosuchidae. In general pelvic structure, the Estemmenosuchidae resemble the South African anteosaurs and tapinocephalians and the Russian tapinocephalians. In detail, however, they show a more primitive stage of evolution, overlaid by characteristic specializations which relate them more closely to the advanced Russian forms than to those of South Africa. Three new genera are erected, Biarmosaurus, fam. Eotitanosuchidae; Chthomaloporus, fam. Brithopodidae; and Molybdopygus, fam. Estemmenosuchidae. One specimen formerly referred to Deuterosaurus Yefremov 1954, and five formerly included in the type of Brithopus Yefremov 1954 are referred to Molybdopygus. The more primitive deinocephalians are from Yezhovo in the Ocher District, Perm Province, while more advanced forms are from Isheyevo, in Tataria, where-therocephalians and other South African elements are also found. It is therefore concluded that the Ochersk beds are older than those of Isheyevo and must be dated to zone I of Yefremov's system. — N. Hotton III.
