| 中文摘要: |
| 河南省鲁山县杨叶沟铅锌矿已提交的(332)＋(333)Pb+Zn金属量约1.5万t,其中Pb最高品位14.99%,最低品位0.51%,平均品位1.54%,Zn最高品位4.38%、最低品位0.70%,平均品位1.28%。通过地质测量和工程揭露等方法,发现铅锌矿体主要赋存于北东向或近东西向构造带内,矿体呈透镜状、豆荚状顺带产出,产状与矿带一致。通过对该矿床分析研究,总结了其成因和找矿标志,认为该区深部沿矿体倾向和部分物化探异常分布区尚有较好找矿前景。通过进一步勘查,矿床规模将会有较大的拓展空间。 |
| 英文摘要: |
| The submitted amount of (332) + (333) Pb+Zn of Yangyegou lead-zinc deposit is about 15,000 t, of which the highest grade of Pb is 14.99%, the lowest grade is 0.51%, the average grade is 1.54%, the highest grade of Zn is 4.38%, the lowest grade is 0.70%, the average grade is 1.28%. Yangyegou lead-zinc deposit is in Lushan County Henan Province. By means of geological survey and engineering exposure, the author finds that the lead-zinc ore body mainly occurs in the northeast or near east-west structural belt, and the ore bodies are lenticular and pod-shaped, the occurrence is consistent with the ore zone. Based on the analysis and study of the deposit, the author summarizes its genesis and ore-prospecting markers, and thinks that there is still a large ore-prospecting space in the deep part of the area along the orebody trend direction and some geophysical and geochemical anomalies. Through further exploration, the scale of the deposit will have a large expansion space. |
