1:500万国际亚洲地质图

1:500万国际亚洲地质图(IGMA5000)是由世界地质图委员会(CGMW)的4个分会、亚欧20个国家的100余名地质学家合作完成的。这是CGMW旗下,第一份IGMA5000;第一份以亚洲为主体,又包括邻区,既表示大陆地质,又表示海底地质的IGMA5000;第一份按国际标准,在ArcGIS平台上编制的数字化IGMA5000。图幅西起阿尔卑斯,东到马里亚纳海沟,北起北冰洋,南到爪哇海沟。从这张图上,不仅可以解读亚洲地质,而且可以研究亚洲与相邻大陆和海洋的地质构造关系。IGMA5000的完成,为亚洲大地构造、成矿规律和资源环境研究建立了一个坚实的基础。

1:5 Million International Geological Map of Asia

The 1:5M International Geological Map of Asia (IGMA5000) under the aegis of the Commission for the Geological Map of the World (CGMW) is a cooperative project launched in 2005 and completed in 2012, which involves more than 100 geologists from 4 subcommissions of CGMW as well as geological surveys and institutions of 20 Asian and European countries. The map area covers whole Asia and its adjacent regions from the Alps in the west to the Mariana Trench in the east, and from the Arctic Ocean in the north to the Java Trench in the south. IGMA5000 is the first digital Asian geological map built on the ArcGIS platform and compiled in accordance with international standards and also the first map that displays the off-shore and on-shore geology within the map area, and therefore the compilation of the map is extremely arduous and challenging. The present map not only provides a fresh insight into the Asian geology with a global vision but also shows the geological relationship between the Asian continent and its neighboring continents and oceans. Its successful completion will surely lay a solid foundation for researches on the tectonics, metallogeny, resources and geological environment of Asia.
