西峡金红石矿床位于秦岭造山带东段南缘,是一个大型角闪质片岩型金红石矿床。矿体赋存于古生界信阳群龟山组第三段,含矿岩石为含金红石角闪质片岩。本文阐述了矿区地质、矿体和矿石特征、钛的赋存状态及分布规律、热液蚀变等,认为该矿床属变质热液改热门造的火山─沉积变质型金红石矿床。

Fluid plays an important role in the ore-forming process. The geological background of Pingdong-Wangshi lead-zinc deposits, a zone in the southwest of Dayaoshan, is very advantageous for the fluid to extract and transfer the ore elements and form deposits. The authors draw a conclusion that the deposits are equivalent to the ore in carbonate rock and named sedimentary transformation deposit. According to geological background, ore-bearing formation, ore structure, host rock alteration, and ore formation temperature...

Fluid plays an important role in the ore-forming process. The geological background of Pingdong-Wangshi lead-zinc deposits, a zone in the southwest of Dayaoshan, is very advantageous for the fluid to extract and transfer the ore elements and form deposits. The authors draw a conclusion that the deposits are equivalent to the ore in carbonate rock and named sedimentary transformation deposit. According to geological background, ore-bearing formation, ore structure, host rock alteration, and ore formation temperature the deposits resemble the Mississippi Valley-type lead-zinc deposit. The authors have studied lots of ore structures in the deposits, and some typical structures such as brecciaform,banding and crustification show that the ore-forming fluid is indispensable for the deposits in the zone.

流体在成矿过程中起重要作用。大瑶山凸起西南缘平硐—旺石铅锌成矿带的地质背景极有利于流体的活动和大型、超大型矿床的形成。据成矿环境、含矿建造、矿体和矿石特征、围岩蚀变、成矿温度等方面对比 ,该区在成因上具有MVT铅锌矿床的特点。诸多矿石组构如条带状、角砾状、皮壳状等的特征均表明该区矿床的形成与成矿流体关系密切。

The late Archaean yanlingguan formation in west Shandong is a typical greenstone belt on the north China platform,it is composed of Komatiite,Hornblende, Leptynit,ferruginous Quartzite and so on,their protolyte is a series supercrust formation of ultramafic-mafic lava rocks and pyroclastic sedimentary rocks,which had been taken on three-epoch of regional metamorphism and their metamorphic grad reach low-pressure amphibolite facies.

The late Archaean yanlingguan formation in west Shandong is a typical greenstone belt on the north China platform,it is composed of Komatiite,Hornblende, Leptynit,ferruginous Quartzite and so on,their protolyte is a series supercrust formation of ultramafic-mafic lava rocks and pyroclastic sedimentary rocks,which had been taken on three-epoch of regional metamorphism and their metamorphic grad reach low-pressure amphibolite facies. Dozens of the pyrite-ore bodies which have different scale distribute in west Shandong granite-greenstone terrane with wein,len and stratoid shapes,and which stretch out as gneissosity as direction.The ore,mainly hosted in pyrite-amphibolite,sulphtenor in the ore usually are from 3.79×10-2 to 31.6×10-2,associated mineralizer are Fe,Ni,Ag etc.According to the above studes of greenstone,ore and bodies,metamorphic metallization,result show that greenstones contain rich mineralizer of the S?Fe?Ni etc.The greenstones are both container rock and source bed.The deposits are referred to as pyroclastic-sedimento-metamorphic type deposit that is telescoped by the metamorphic hydrothermal.

鲁西地区新太古代雁翎关组由科马提岩、角闪质岩石、变粒岩和含铁石英岩等组成 ,其原岩为一套超镁铁质镁铁质火山熔岩及火山碎屑沉积的表壳岩建造 ,经历了三期区域变质作用 ,变质程度达低角闪岩相 ,是华北地台上一个典型的绿岩带。鲁西花岗岩绿岩带中分布有大小黄铁矿脉数十条之多 ,呈层状、透镜状或脉状沿片麻理方向展布 ,硫品位 3 .79%~ 3 1.6% ,伴生有用组分Fe、Ni、Ag等。通过对绿岩、矿体和矿石特征、S、Fe分布及变质成矿作用等方面的研究 ,证实绿岩中含有丰富的S、Fe、Ni等造矿元素 ,认为绿岩既是赋矿岩石亦是矿源层 ,矿床属变质热液叠加的变质火山沉积型硫铁矿床。
