【Abstract】 The Yili block is divided into three tectonic elements by the Zhaoshu-Tekse fault , that is, the southern slope of the Boluokenu-Nilek fault, the northern slope of Boluokenu fault, and the Bortala-Yilinhabirga fault. From the northeast to the southwest, they are respectively the Yining crest zone, the Boluokenu crest zone and the Wenquan-Sailimu wavy trough tectonic belts. The structural evolution process is that the Wenquan-Sailimu and the Yili blocks were mosaiced together into the northwest margin of the Talimu massif in the various periods of the proterozoic era, and then they underwent a steady developing process and evolved to the margin sea basin in the early stage of the Cambrian-Middle Ordovician. In the late period of the middle Ordovician, they began to rift and the Wenquan-Sailimu block departed from the Yili block. In the late Silurian period because the Boluokenu sea trough was closed by compression,both of the blocks were masaiced together. In the late Palaeozoic era, the fault trough-seg acted repeatedly. The Middle Carboniferous period was a main age that the Yilian-habirga crest zone was put together with the Wenquan-Sailimu and the Boluokenu tectonic belts.The discussed regions are divided into three metallogenic provinces.更多还原
