The International Geological Congress held every four years is a grand event for displaying the latest achievements in geological science and technology and carrying out academic exchange.After the 31st IGC, the Chinese geologists, like their counterparts in the rest of the world, started to pay more attention to the issues facing the world today, including the shortage of energy and 相似文献

Since the discovery of a lot of eclogites with coesite and diamond inclusions related to the continent-continent collision-orogeny environment, the ultrahigh-pressure metamorphism (UHPM) in the Dabie-Sulu has aroused great interest in geologists. Experimental studies have proved that such minerals as diamond, coesite and omphacite etc. formed at pressures 2-5 GPa (and corresponding temperatures). However, it does not mean that by the formation pressure we can directly determine that the metamorphic rocks are the products of a deep-seated subducting plate downward to depths of 100-200 km and then returning to the surface. The calculation method of P/SW (depth=pressure/specific gravity), i.e. the formula of pressure=depth×specific gravity, needs to be thought about again. 相似文献
