中文摘要: 通过野外地质研究发现,本区发育有一套特有的构造组合。这些构造(S-C面理、线理、褶皱、不对称构造等)在本区内呈组合出现。结合室内的分析鉴定看出岩石具有粒内应变构造、核幔构造。进一步表明水泉沟地区为一条轴向北东—北北东韧性剪切带。铜多金属矿体的分布与韧性剪切带的轴向有一定的关系,并出现带状分布,韧性剪切带其次一级构造控制矿体的分布。本区矿化特征也与韧性变形强度有一定的关系:在矿化较好部位,从糜棱岩到弱糜棱岩及糜棱岩化岩矿化出现矿化减弱的趋势。
Abstract:Through the field geological research, a set of unique tectonic assemblages was found in this area.These structures (S-C planes, lineations, folds, asymmetric structures, etc.) appear in combination in this area. Combined with the analysis and identification in the laboratory, it can be seen that the rock has internal strain structure and nuclear mantle structure.It is further shown that Shuiquangou area is an axial NE-NNE ductile shear zone.The distribution of copper polymetallic ore bodies is related to the axial direction of the ductile shear zone, and a banded distribution occurs.The distribution of the ore bodies is controlled by the secondary structure of the ductile shear zone.The characteristics of mineralization in this area are also related to the strength of ductile deformation to some extent: in the better parts of the mineralization., mineralization from mylonite to weak mylonite and mylonitic mineralization tends to be weakened.
