青海开心岭地区铁多金属矿床地质特征及成矿模式

摘要

开心岭地区铁多金属矿床产于中二叠世诺日巴尕日保组二岩段的基性火山岩中,铁、铅锌、铜矿化及其围岩蚀变具有明显的垂向分带性,为热水喷流沉积型矿床( VMS型). 区域上分布的许多矿点具有与开心岭铁矿相类似的成矿地质条件和找矿潜力. 作者对本区铁多金属矿成矿地质特征、控矿因素、矿床成因、成矿规律、成矿模式及找矿方向进行进一步的归纳总结,提出找矿方向,指导下一步勘查工作.%The Fe&polymetallic deposit in Kaixinling area is located in the basic vocanic rocks in the second phase of Nuoribagaribao group of the Middle Permian.The mineralization of Fe, Pb, Zn and alteration of mass rock are characterized with clear vertical zonality, and volcanic jet type ore deposits ( VMS type) .Many ore deposits are distributed in the region with similar oregenetic condition and prospecting potentials.Summarization is taken on the features, oregenesis and ore-con-trolling factors, and prospecting for further exploration work.
