Abstract

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
