摘    要:铧厂沟金矿床位于勉略缝合带中泥盆系三河口群郭镇岩组中。含矿与容矿岩系为泥盆系三河口群郭镇岩组中的细碧岩和结晶灰岩。主控矿构造为寨子湾韧-脆性剪切构造带。围岩蚀变包括退化蚀变和矿化蚀变。在矿区内产出南北两条矿化带,矿石类型为蚀变细碧岩型、黄铁绢英片岩型和石英脉型。主要的金属矿物为黄铁矿和黄铜矿,金矿物是自然金。韧脆性剪切构造叠加和岩石强烈变形、彻底退化蚀变以及后期含矿热液交代与充填是主要的成矿作用,属于火山-沉积岩系中的类卡林型金矿床。

关 键 词:容矿岩系   韧-脆性剪切带   类卡林型金矿   铧厂沟   陕西略阳

Abstract:Huachanggou gold deposit locates in Guozhen Formation of Sanhekou Group of Devonian Mianxian-Lueyang suture zone.Mineral-bearing series is spilite and crystal limestone. The main ore-controlling structure is Zaiziwan brittle-ductile shear zone. Host-rock alteration is made up of retrograde and mineralized alteration. Huachanggou ore body can be divided into south and north ore belts. Ore type contains altered spilite and altered pyrite quartz-sericite, as well as quartz vein. The main ore minerals are pyrite chalcopyrite and natural-gold. The main mineralization includes brittle-ductile shear superimposed and strong deformation and wholly retrograde alteration and later period mineral-bearing hydrothermal exchanged and depositing,which belong to para-Carlin type gold deposits in the volcanic-sedimentary series.
Keywords:ore-bearing series  brittle-ductile shear zone  para-Carlin gold deposits  Huachanggou  Lueyang Shaanxi
