新疆于田普鲁—阿羌石炭纪裂谷 ,发育于塔里木板块晚古生代被动陆缘之上。裂谷发展经历了两个阶段 ,即早石炭世裂谷形成发展阶段和晚石炭世—早二叠世裂谷敛合阶段 ,形成发展阶段主要为双峰式火山岩建造 ,敛合期以钙碱性安山岩、基性玄武岩为主间夹灰岩、砂砾岩等。该裂谷为塔里木南缘晚古生代活动带的一部分。活动带内大量火山岩浆活动为以铜为主的多金属成矿提供良好条件 ,同时深大断裂活动使金刚石成矿成为可能。对该活动带的深入研究不仅对古特提斯演化研究具有重要意义 ,而且对指导找矿具有非常重要的现实意义。
Xinjiang Yutian Pulu - Aqiang Carboniferous rift, developed in the Tarim plate late Paleozoic passive continental margin. Rift Valley has experienced two stages of development: the Early Carboniferous rift formation and Late Carboniferous - Early Permian rift convergence stage, the formation of the development stage is mainly bimodal volcanic rock formation, convergent period of calcium and alkali Andesite, basaltic basaltic intercalated limestone, glutenite and so on. The rift is part of the Late Paleozoic belt on the southern margin of Tarim. A large number of volcanic magmatism in the active zone provided favorable conditions for the copper-dominated polymetallic mineralization, while deep-seated faults made diamond mineralization possible. In-depth study of this activity zone is of great significance not only for the study of the evolution of the ancient Tethyan, but also for the exploration of prospecting.
