| 中文摘要: |
| 陕西凤县—太白金铅锌矿集区(凤太矿集区)地质作用复杂，构造、岩浆活动强烈，成矿条件优越，是国内重要的金属矿产资源基地之一。20世纪以来，该区发现了多个大中型金铅锌矿床，但目前许多矿山资源开采殆尽，面临枯竭。自 21世纪初以来，凤太矿集区实施了不少地质找矿项目，但找矿成果不甚显著。笔者通过对典型矿床的深入研究，详细总结了矿体赋存特征、成矿规律、控矿因素和找矿标志，建立了矿集区综合成矿模式及找矿预测模型，构建了区内金、铅锌矿床“天空地井”三维立体找矿技术方法组合。依据研究成果，对 6个找矿靶区进行勘查验证，新增探获金推断以上资源量 37 t、铅锌推断以上资源量约 200万 t，实现了区内找矿的重大突破。 |
| 英文摘要: |
| The Fengxian-Taibai Au-Pb-Zn ore concentration area (Fengtai mineral concentration area) inShaanxi Province has complex geological processes, strong tectonic and magmatic activities, and excellent mineral-ization conditions. It is one of the important bases of metallic mineral resources in our country. Since the last cen-tury, a few large and medium-sized gold, lead and zinc deposits have been discovered in this area. However, manyof the mines have been nearly exhausted and are facing resource depletion. Since the beginning of the 21st century,although many geological exploration projects have been implemented in the Fengtai mineral concentration area, theresults of exploration have not been very significant. Based on the scientific research projects and various explora-tion projects undertaken in the past decade, the authors have conducted in-depth research on typical deposits, sum-marized in detail the ore body occurrence characteristics, regularity of ore formation, ore-controlling factors and ex-ploration indicators, established a comprehensive mineralization model and exploration prediction model for themineral concentration area, as well as developed a three-dimensional stereoscopic exploration technology andmethod combination for gold and lead-zinc in the area, including "air, space, ground and underground". Based onthe research results, six exploration targets areas have been investigated and verified, and an additional inferredgold resource of 37 tons and an inferred lead-zinc resource of about 2 million tons have been newly discovered,achieving a major breakthrough in exploration in the area. |
