| 摘 要： | 福建省柘荣县马坑银矿产于上侏罗统-下白垩统陆相酸性火山岩中,矿体严格受断裂（F1,F2）及其派生裂隙的控制。矿床发育绢云母化、硅化、黄铁矿化、黄铁绢英岩化、青磐岩化等中低温热液蚀变,矿体地表呈密集细脉状,深部为简单板状、透镜状。矿石矿物以自然银为主,次为辉银矿,含少量方铅矿、闪锌矿等。矿石工业类型为硫化矿,矿床成因为受断裂构造控制的中低温浅成火山热液充填交代型银矿床。

| Abstract: | Makeng Ag deposit in Zherong county,Fujian province occurs in continental acid volcanics of Upper Jurassic-Lower Cretaceous series and is controlled strictly by fault F1,F2 and the derivative fractures.In the deposit are develped medium-epithermal alterations,such as serisitization,silicification,pyritization,phyllic alteration and propyllitization.At surface it is in closely spaced small veins and simple tabular body and lens to depth.Native silver is the main ore mineral then argenite and a few galena and sphalerite.Industrially the ore is of sulfidation type and genetically the deposit is the fracture-controlled medium-epithermal fluid filling and replacement silver deposit.. |
