广东河台整装勘查区百旁金矿成矿规律

Metallogenic law of Baipang gold deposit in the Hetai integrated prospecting area

百旁金矿是广东地质五队近年来新发现的一处中型蚀变糜棱岩型金矿。百旁金矿地处粤西—桂东成矿带东段NE向罗定—广宁断裂带北东端部位,矿体受糜棱岩带内面理、裂隙带控制;金矿化具明显的以硅化、硫化物为中心的对称性分布特征,金矿体具有平行斜列、侧伏的分布规律,表现为向NE向侧伏;区内金矿化富集主要与热液活动有关,燕山期的重熔花岗岩侵入的同时伴随有富含硫化物的含金热液充填在糜棱岩、断裂带内而成矿。

Baipang gold deposit is a recently discovered medium size alterted myllonite type gold deposit by the 5th geological team of Guangdong province.It occurs at northeast end of NE Luoding-Guangning fault belt in the east part of the west Guangdong-the east Guangxi ore belt.Ore bodies pitch in NE direction and occur in en edhelon and are controlled by foliation and fracture zone.Mineralization is distributed symmetrically on either sides of the silicification and sulfide center.In the area mineralization is related to hydrothernal fluid activity.Intrusion of of Yanshanian remelted granite is acompanied by contemporaneous filling of sulfide-rich Au-bearing hydrothermal fluid into myllonite and fractural zone and the ore formed there.
