摘要
湘南“大义山式构造”表现为基底走滑断裂控制的左行发辫状构造 ,至少经历了早期左行脆—韧性压扭 ,晚期张性碎裂两个变形阶段。区域上构成郴州—邵阳北西向构造岩浆成矿带的南东段 ,其构造演变是构造岩浆成矿带构造发展史的缩影。它不权控制了大义山岩体的产出空间 ,而且是热液型Sn、Sb、Pb、Cu矿床控矿构造。
Dayishan-style structure”in southern Hunan appears the sinistral hair-braided-style structure controlled by basement strike-slip fault zone and underwent two stages deformation at leasti.e.:the earlier stage of sinistral brittle-ductile transpression and the later one of tension cataclasis.Regionally,it constitutes the east-southern section of Chenzhou-Shaoyang structural magmatic metallogenic zone,its tectonic evolution is the epitome of structural development history of Chenzhoushaoyang NW-trending structural magmatic metallogenic zone.It not only control temporal distribution of Dayishan lithesome,but also is the ore-controlled structure of hydrothermal solutiontype mineral deposits shuch as Sn、Sb、Pb and Cu et al.
