摘要
邵阳 -郴州北西向构造带内花岗岩发育 ,且呈北西向有规律地断续分布 ,与成矿关系密切。由于构造环境、围岩条件、剥蚀程度等方面存在较明显的差异 ,可分为北西段和南东段 ,它们在花岗岩成岩成矿方面也各具特色。北西段花岗岩主要为“S”型 ,侵位较深 ,以主动侵位机制为主 ,成矿距岩体接触带较远 ,以Au ,Sb为主 ;南东段以“S”型花岗岩为主 ,有少量”I”型花岗岩 ,侵位较浅 ,成矿一般在岩体接触带附近 ,以W ,Sn ,Pb ,Zn ,Cu和Ag为主。
The NW striking Shaoyang Chenzhou tectonomagmatic belt in Hunan Province is an important one and shows close relationship with mineralization in central south Hunan Province. Granites in this area show great difference in tectonic setting,wallrock and denudation depth: granites in the northwestern part is mainly S type with greater emplacement depth and is predominated by forceful emplacement,related Au and Sb mineralization is usually far from mineralization granites in the southeastern part,however,include S type and I type with smaller emplacement depth,and the related W,Sn,Pb,Zn,Cu and Ag mineralization is nearby the contact zone.
