摘要
自大哈拉军山火山岩系建组,并确定其时代为早石炭世以来,它在西天山及伊宁地块的地质、成矿作用的研究中所起的作用是举足轻重的,在全面分析以往资料和发现中生代鱼化石的基础上,重新厘定大哈拉军山组的时代为三叠—侏罗纪,将对西天山及伊宁地区的构造属性、构造单元划分、发展演化及矿产资源的开发均会起到重要的作用。
Dahalajunshan Formation, which occurs in Yining Block,has been very important in study of the regional geology and ore formation since predecessors set up this volcanic formation and confirmed it to be Carboniferous. On detailed studies on the previous data and discovery of the Mesozoic ichthyolite, we propose that Dahalajunshan Formation should be Triassic to Jurassic. This study will be of great significance in study of tectonic property, evolution, unit subdivision and mineral resources exploration in Yining Western Tianshan area.
