摘要
产于震旦-奥陶系葫芦河群石嘴组地层之断裂破碎带中的花石山构造(热液)蚀变岩型金矿,矿床规模已达中型。矿石以含金石英脉型及构造蚀变岩型为主,褐铁矿、黄铁矿是主要的载金矿物。围岩蚀变以硅化、褐铁矿化、黄铁矿化、绢云母化为特征。海相沉积岩及中酸性火山岩、脆韧性断裂构造、中酸性岩浆侵入“三位一体”是控制矿床形成的基本条件。区内成矿条件优越,具有形成大型金矿的可能性,近东西向断裂蚀变延伸带是寻找金矿的有利地段。
Huashishan （Huashi Mountain） tectonic （hydrothermal） altered-rock gold ore deposit is a medium-sized scale deposit that located within the faulted-fracture zone in the Shizui formation of Hulu River group of Sinian-Ordovician age. The ore mainly includes two components： auriferous quarts and tectonic altered-rock. Limonite and pyrite are the major gold-cartier in the mineral. The features of wall-rock alteration are silication, limonitization, pyritization and seficitize. The basic conditions of ore deposit-forming is controlled by the ＂tri-unity＂ which are marine sedimentary rock and inter mediate-acid volcanic rock, brittle-ducltile faulted structure as well as intermediate-acid magmatic intrusion. It is possible to form massive gold ore while the ore-forming condition is better in the region. The faulted-altered-extension zone is a more favorable place for searching gold-ore deposit along the east-west trending.
