第32届国际地质大会区域地质研究进展

第32届国际地质大会汇集了全球典型地区的区域地质研究的最新成果。前寒武纪克拉通和年轻造山带的岩石圈差异表明在晚古生代欧洲是一个复杂的沿着由于罗得利亚超大陆裂解而形成的波罗的海边缘增生的地体拼接带。阿拉伯—努比亚地盾在新元古代也经历了裂解、俯冲及碰撞固结的过程。利用新资料分析了Afar地幔柱与板块构造事件对红海演化过程的影响程度。通过逆冲推覆构造确定里海和咸海地区一期强烈的挤压应力场与油气及矿床的定位密切相关。喜马拉雅结晶岩系年代的确定和第三纪以来造山带地质构造的演化取得了很大的进展。大会上展示了阿尔卑斯地区和区域地质有关的最新研究成果,分析了北美及加勒比地区区域地质研究的进展与现状。

ADVANCES IN REGIONAL GEOLOGY IN THE 32ND INTERNATIONAL GEOLOGICAL CONGRESS

There are a whole series of recent achievements about regional geology presented in the 32nd International Geological Congress. A comparative study of PreCambrian period and younger orogens indicated that as reflected in structures within these areas, Central Europe has experienced a complex tectonic history during the Late Palaeozoic. These terranes were accreted along the margin of Baltica that was formed during the break-up of Rodinia. New data provide a more complete analysis on how the Afar plume and plate-scale tectonic events interacted the Red Sea Basin evolution. An intensive compressive structural stress field resulted from thrust existed in Caspian and Aral sea regions controlled the locations of oil, gas and deposits. Geochronology of Himalayan crystallines and oregenic evolution since Tertiary made great progress. Recent regional geological results in Alpine region are presented. The advances and actuality in North American and Caribbean area are reviewed during the congress.
