作者通过对湖南郴州枞树板铅锌矿围岩及含矿构造带岩石的X光岩组分析 ,认为在构造变形过程中 ,原岩粒度越细 ,对变形的反映越敏感。在相同的变形条件下 ,较细的变质砂岩石的石英定向组构比较粗的变质砂岩内明显 ,板岩和粉砂质板岩的定向组构最明显。枞树板地区近EW向褶皱变形组构表现强烈 ,近SN向褶皱变形组构较弱。矿化热液的蚀变作用破坏了岩石中早期褶皱变形组构 ,但铅锌矿脉内的石英没有明显的生长组构 ,说明在矿化和含矿石英脉成生过程中没有明显的张性充填结晶表现 ,而是一种以交代为主的矿化形式。这与从其它地质地球化学研究取得的关于本区构造变形和矿床成因的认识相吻合。
Based on the analysis of the X-ray lithofacies of the surrounding rock and the ore-bearing structural rocks of the Fushulian Pb-Zn deposit in Hunan Province, the authors believe that the finer the original rock particle size during the tectonic deformation, the more sensitive the deformation is. Under the same deformation conditions, the finer metamorphic sandstone has more obvious quartz orientation structure than the coarse metamorphic sandstone, and the orientation structure of slate and silty slate is the most obvious. Fir tree plate near the EW fold deformation shows strong, nearly SN fold deformation is weak. The alteration of mineralized hydrothermal fluids destroyed the early fold-deformation structures in the rocks, but there is no obvious growth structure of quartz in Pb-Zn veins, indicating that there is no obvious tension in the mineralization and ore-bearing quartz veins Filling crystallization performance, but a form of mineralized to account. This is in line with the understanding gained from other geo-geochemical studies about the tectonic deformation in the area and the genesis of the deposit.
