青海开心岭铁矿床地质特征及矿床成因探讨

摘要

Based on the basic geological survey,we analyzed the geological background,including geological characteristics of ore bodies and mineral quality in Kaixinling iron deposit.It divided the strata of Kaixingling area into Nuoribagaribao Formation of Kaixinling Group and Wuli Group.The fracture zones in NE faults were important mineralization structures and ore bodies were closely related to volcanic rocks.The genetic type of the deposit was volcanic exhalation-sedimentary deposit.%通过在开心岭地区开展基础地质调查工作,分析开心岭铁矿的区域地质背景、矿体地质特征和矿石质量,将该区地层划分为开心岭群诺日巴尕日保组和乌丽群.区内NE向断裂破碎蚀变带发育,为重要赋矿构造且铁矿体与火山岩关系密切;矿床成因类型为火山喷气-沉积型矿床.
