| 中文摘要: |
| 湖南黄沙坪铅锌多金属矿位于湖南省郴州市桂阳县境内,是湖南省内最大的铅锌开采矿山和铅锌原料基地。由于多年开采,铅锌资源已处于深度危机,为此,矿山一方面大力开展矿区边深部铅锌地质探矿工作,一方面在矿区外围寻找新的铅锌资源点。根据矿山最新施工的地表深钻资料显示,在黄沙坪矿区北部29线深部发现了隐伏的细粒花岗小岩体,在岩体接触带和上部碳酸盐岩裂隙中均有较好的铅锌矿化和弱夕卡岩化等现象。在总结控矿地质因素和成矿模式的基础上,重点分析了13～29线的矿化特征,并结合物化探异常特征和成矿规律,对黄沙坪矿区北部和三光井地区的成矿潜力做出了预测。通过进一步的勘查和验证,预测黄沙坪矿区北部外围地区新增铅锌资源量30万t以上。 |
| 英文摘要: |
| The Huangshaping lead-zinc deposit is located in Guiyang county, Chenzhou city, Hunan Province. It is the largest lead-zinc mine and lead-zinc producing base in Hunan Province.Due to many years of mining operation, the lead-zinc resources are almost mined out.Therefore, on the one hand, the mine vigorously carried out geological prospecting work in depth of mine, on the other hand, explored in the northern periphery of the mine.According to the latest drilling data, a small hidden fine grained granite rock mass was discovered at depth of Section Line 29.Meanwhile, sounding lead-zinc mineralization and weak skarn alteration were found nearby the contact zone and in fissures within the upper carbonate wallrock.On the basis of summaring ore-controlling geological factors and metallogenic model, the authors mainly analyzed the mineralization characteristics within area between Section Line of 13 and Line 29, and predicted the metallogenic potential for the northern area of Huangshaping mine and the Sanguangjing region.By the test engineering work and verification, more than 300 000 tons lead and zinc metals resources could be obtained in the northern periphery of Huangshaping mine. |
