| Abstract: | The altered rock type of gold deposlt occurs in fracture zones which are developed in theexocontact zone of Yanbagiao rockbody. lt is a new type of gold deposit which is discoveredin w-sb-As-Au mineralized belt in Western Hunan in recent years. The deposit ischaracterized by low grade of Au, large thick and even mineralization. This discovery furthershows metallogenic potentialities of Proterozoic strata and of shear zones developed inProterozoic strata and a practical significance for prospecting in the district |
