摘要:

抱伦金矿床是海南省新近发现的大型金矿床之一,属于发育于下志留统陀烈组浅变质岩系中受断裂裂隙构造控制的岩浆热液型金矿床。研究表明:与成矿有关的尖峰岭复式岩体中心相的侵位时代为236~232Ma,经历了长期多次多阶段的侵位,抱伦金矿床的成矿年龄确定为大约220Ma(印支期),二者的年龄差大约为16~12Ma。岩体的脉动式活动为形成高品位金矿石提供了物质和动力来源。

Abstract:

Baolun gold deposit is a large-scale magmatic hydrothemal type gold deposit found recently in Hainan ProVince.It occurs in the Tuolie Fomation epimetamorphic rock of Lower Silurian and is controlled by fault structures.Rock-forming age of central facies of Jinfengling duplicate rock body related to the mineralization is 236 to 232 Ma.The rock body went through long-term and multi-phases intrusions.Mineralization age of Baolun gold deposit is 220 Ma(Indosinian Stage),the age difference between them is 16 to 12 Ma.Inpulse activities of the rock body supply material and power for forming of high-grade ore.

Key words: Baolun gold deposit, mineralization age, Hainan Province
