| 中文摘要: |
| 沙溪和冶父山同处郯庐断裂带内部,两个地区均具有极为发育的石英脉体,成矿地质背景相似。但含矿性迥然不同。本文在这两个地区岩体特征差别研究的基础上,重点讨论了两区脉石英特征的一系列差异,研究的结果表明:沙溪区石英脉体的形成受控于持续且稳定的区域应力场的作用;冶父山区石英脉体的形成受控于短期多变的局部应力场的作用。两个地区脉石英在包裹体及红外光谱等特征上均存在明显的差别,这些差别可作为石英脉体含矿性评价的准则。 |
| 英文摘要: |
| Both Shaxi and Yefushan are located within the TanchengLujiang deep fault belt. Stockwork veins are developed in both areas, The geologic setting are quite similar, but the ore-bearing characteristics are much diffierent. The contrasting investigations of intrusive rocks and the stockwork veins between the two areas have shown that the quartz-veins in Shaxi are formed in a stable regional tectonic-stress field, and the quartz-veins in Yefushan are formed in a temporal and changeable local tectonic-stress field. The characteristics of inclusions and infra-red spectrum of quartz in both areas are different. These distinctions can be used as criteria in prospecting stockwork veins. |
