木合塔尔·扎日, 张晓帆, 陈斌, et al. 东天山造山带晚古生代构造演化与多金属矿产成矿规律[J]. Journal of Xinjiang University (Natural Science Edition in Chinese and English), 2010, 27(1): 5-12.
东天山造山带在晚古生代时期经历了四阶段演化过程
即泥盆纪吐-哈古大洋形成
早石炭世俯冲造山
晚石炭世碰撞造山
以及二叠纪造山期后造山带的进一步变形.自北而南划分为大南湖-哈尔里克岛弧带、康-阿板块碰撞缝合带和中天山岛弧带等三个一级构造单元(带).东天山的矿产严格受构造控制
在晚古生代构造演化期间发育的铜、金、铜镍硫化物等多金属矿床的成矿具有十分明显的时-空演化规律.发育有斑岩型铜矿床、铜(镍)硫化物矿床、矽卡岩型铜多金属矿床、韧性剪切带型金矿床和热液型金矿床等矿床类型.这些矿床在东天山地区构成四条大的成矿带:康古尔断裂以北铜矿带;金、铜镍硫化物矿床成矿带(北带);阿齐山-雅满苏铁(铜)、银多金属成矿带(南带)和中天山地块铁、铅锌、银成矿带.
The eastern Tianshan Mts orogenic zone during the late Paleozoic underwent four stages geolog-ical evolution including the formation of Tupan-hami ocean in Devonian
subduction-type orogeny in early Carboniferous
collisional orogeny in late Carboniferous and post orogenic further deformation of the plate suture in Permian.Three obvious tectonic belts of the eastern Tianshan Mts orogenic zone
represented by Dananhu-haelike island arc zone
Kang-a plate suture zone
Middle Tianshan Mts island arc zone.
can be subdivided from north to south.Distribution of Ore deposits in the eastern Tianshan Mts is remarkably controlled by tectonics
and the copper
gold and magmatic Cu(Ni) sulfide metallogenic deposits of late Pa-leozoic display obvious temporal-spatial evolution regularity.They are porphyry copper deposits
magmatic Cu(Ni) sulfide deposits and ductile shear zone type gold deposits
skarn-type copper-ploymetallic deposits and hydrothermal gold deposits.The above different type deposits spatially formed four large metallogenic belts: Copper metallogenic belt to the north of Kangur fault;Gold
copper and nickel metallogenic belt(North Belt);Iron
copper
and silver polymetellic metallogenic belt of Yamansu-Aqqikkudug area(South Belt);Iron
lead-zinc and silver metallogenic belt.
