塔里木地块周边的含矿建造和资源远景

塔里木地块经历了前寒武纪陆核增生-地块奠基、早古生代边缘裂解-开合拼贴、晚古生代裂谷叠加-板块统一、中新生代盆山耦合-地貌定形的四大构造演化阶段,在天山、昆仑山、阿尔金山一带形成了六大含矿建造和多种成因类型的金属矿床.周边地区有前苏联中天山、西南天山、秦祁昆、古特提斯四条邻国和邻区的巨型洲际级成矿带通过.从已知的近千处矿床(点)、矿化点和物化探异常的宏观分析和局部重点普查找矿信息来看,塔里木地块周边的金属矿床远景可观,潜力巨大,某些成矿带有可能成为我国矿产资源的后备勘查基地.

ORE-BEARING FORMATIONS AND MINERAL RESOURCES PROSPECT OF THE PERIPHERAL REGION OF TARIM BLOCK, CHINA

The developing of Tarim Block may be divided into 4 stages including accretion of nuclear area and establish of block in Pre_cambrian,diverging and alagamating of margin in early Paleozoic,super position of rift and unification of plate in late Paleozoic,coupling of basin-mountains and fixed form of landform in Mesozoic-Cenozoic.There are 6 ore-bearing formations and various genetic types ore deposits in Tianshan,Kunlun and Aerjinshan belts in the peripheral region of Tarim Block.The 4 giant intercontinental metallogenic belts pass through the region.According to the micro-analysis on near a thousand deposits and anomaly of geophysical-geochemical prospecting,and informations for prospection,the mineral resources of the region are considerable prospect.Some metallogenic belts are the key to exploration.
