| 中文摘要: |
| 通过对湖南郴县枞树板脉状铅锌(银)矿床控矿(含矿)断裂构造的详细研究,认为控矿断裂构造内部具有弧形断层面及其所夹持的构造透镜体组成结构形式;控矿断裂的形态、产状、规模和分布控制矿化带及矿体的形态、产状、规模和分布;控矿断裂的结构形式和力学性质影响并控制矿化形式和矿化富集程度;富矿体产在控矿断裂内部弧形断面较为发育且又较破碎的部位;富矿体单体产出特征是呈不等轴透镜体状,长轴向南西侧状,侧伏角55°～60°,长(斜高)与宽之比近于2∶1,富矿体组合规律是斜列状,自北东向南西逐个降低出露标高,轴线向南西侧伏,侧伏角15°～20°。 |
| 英文摘要: |
| Based on the study of ore controlling fault structures and their relation to the mineralization the authors point out as follows:(1)the ore controlling fault zone includes several arcuate fault surfaces and structural lenticular blocks;(2)the shape,attitude,size and distribution of the ore body and mineralization zone are controlled by those of the fault,and the types and enrichment of mineralization,by internal texture and mechanical property of the fault;(3)the ore shoots occur with well developed arcuate fault surfaces and fractural rocks;(4)the single ore shoot is shaped as nonequant lenticular with long axis pitching to southwest at angles of 50 60° and the ratio beween length and width of 2/1;(5)the ore shoot assemblage is inenechelon arrangement,thus making the outcropping level of the ore shoot lower and lower from northeast to southwest along the mineralization zone;Pitch of the axial line is 15°-20°. |
