摘要: 新疆滴水铜矿床位于库车拗陷盆地西南缘，为典型新生代陆相砂岩型铜矿床.矿体呈层状，主要产于上覆灰色泥灰岩与下伏灰白色中粗粒/中细粒砂岩接触部位.矿体品位与Fe2+呈显著正相关而与Fe3+呈负相关.矿石矿物以赤铜矿为主.综合研究认为，新疆滴水铜矿形成经历了原生沉积—成岩期改造—表生氧化淋滤几个阶段，矿床应属于沉积改造型陆相砂岩铜矿床.

Abstract: The Dishui copper deposit in Xinjiang Uygur Autonomous Region, a typical Cenozoic lacustrine sedimentary rock-hosted deposit, lies in the southwestern margin of Kuqa depression basin. The ore bodies occur as stratiform, between the overlying grey marl and the underlying greyish white medium-grained sandstone. The copper grade is positively related to Fe2+ while negatively to Fe3+. Cuprite is the major ore mineral. The synthetic research indicates that the Dishui copper deposit experienced several genetic stages such as syn-sedimentary, diagenetic reformation and oxidation leaching. The deposit belongs to sedimentary transformation lacustrine sedimentary rock-hosted copper deposit.
