Paleozoic tectonics and its related endogenic metallogeny in Tianshan-Altay region
摘要
Abstract
The study of the Paleozoic tectonics and endogenic metallogeny in the Tianshan-Altay region constitutes an important and interesting project.The Altay area belongs to Early Paleozoic collision zone,and the Tianshan area belongs to the early period of Late Paleozoic (Late Devonian-Early Carboniferous) collision zone; they both resulted from nearly NS-trending shortening and collision.However,influenced by the distant effect of the compressional action of the Ural collision belt in the Late Carboniferous-Early Permian period,the Tianshan-Altay region experienced weak eastward compression,resulting in the change of NW-trending faults into sinistral strike-slip faults and the conversion of nearly EW-trending faults into dextral strike-slip ones as well as the crushing of the rocks to a certain extent,thus forming a lot of world-famous endogenic metallogenic ore deposits.In Asian continent,the strongest collision period is not necessarily the most favorable period for endogenic metallogeny,and therefore the "orogenic metallogeny hypothesis" should be treated carefully.Some suggestions concerning the prospecting for concealed endogenic metallogenic ore deposits are also put forward in this paper.关键词
