摘　　要：近年来在阿尔金、祁连山和东昆仑地区的沉积型锰矿找矿工作取得了突破性进展。从空间分布特征看,这些锰矿均沿柴达木盆地周缘展布。前人曾针对单个矿床地质特征进行过研究,但对于柴达木盆地周缘的锰矿为什么主要形成于中—新元古代至早古生代、锰矿与柴达木地块及周缘造山带演化之间的关系等尚缺少深入的研究与总结。本文从东昆仑、阿尔金、祁连山等环柴达木盆地周缘造山带的角度,分析了沉积锰矿床地质特征和产出规律,重塑了原特提斯洋在青藏东北部的演化过程,为深入理解原特提斯构造演化与沉积锰矿成矿作用的关系提供证据。In recent years,breakthrough progress has been made in the exploration of sedimentary manganese deposits in the Altun,Qilian and East Kunlun Mountains.From the perspective of spatial distribution characteristics,these manganese deposits are distributed along the periphery of the Qaidam Basin.Previous studies have investigated the geological characteristics of individual mineral deposits,but there is a lack of research on why these manganese deposits distributed along the periphery of the Qaidam Basin were formed in the Middle-Neoproterozoic and Early Paleozoic.The relationship between these manganese deposits and the evolution of the Qaidam Block and surrounding orogen is still a lack of in-depth research and summary.This article analyzes the geological characteristics and occurrence patterns of sedimentary manganese deposits;reshaping the evolution processes of the original Tethys Ocean in northeast of Tibet,to provide assistance for a deeper understanding of the tectonic evolution of the original Tethyan region.
