| 中文摘要: |
| 辽宁省调兵山硅灰石矿为特大型矿床,矿床分为3个矿段,控制程度较高的为泉眼沟矿段。硅灰石矿体主要产于古生界富拉堡子岩组硅化大理岩层内,矿体受层位、岩性和岩浆岩的控制。矿体走向NEE向,倾向SE,矿化带长约2 000 m,出露宽度14~65 m。矿化带伴生有金、钼、铅锌、银等金属元素。鉴于矿体与围岩有较显著的物性差异,特选择覆盖区段进行激电中梯剖面测量,获得3条走向NNE向的电阻率异常带。推测视电阻率在2 400~900 Ω·m之间的异常区域为隐伏大理岩和硅灰石矿体赋存的最有利部位。6个钻孔的验证均见到硅灰石矿化,揭示了区内进一步扩大硅灰石储量的远景。 |
| 英文摘要: |
| Diaobingshan wollastonite deposit is a super-large ore deposit. Regionally, it occurs in middle of the east ore belt. There are three ore blocks of which Dongquangoublock is closely controlled. Wollastoniteore bodies are mainly in silicified marble of Paleozoic Fulabuzi formation trending NNE and dipping to SE. They are controlled by horizon, lithology and magmatic rock. The ore belt is 2 000 m long with outcrop 14~65 m wide and by-products of Au, Mo, Pb, Zn and Ag. Because physical property of the ore body is quite varied with that of the wall-rock three IP intermediate gradient sections are selectively surveyed at the area with sedimentary cover and three resistivity anomaly trending NNE are located. It is inferred that 2 400~900 Ω·m anomly implies the space where blind marble and wollastonite body occur. Six test drill holes hit wollastonite mineralization thus the working area is potential for exploration. |
