| 中文摘要: |
| 以贵州省安龙县风洞金矿点为研究对象,对风洞周围地质矿产进行详细调查,出露的地层由上到下依次为下三叠统永宁镇组、下三叠统夜郎组、上二叠统龙潭组,含矿岩系主要赋存于夜郎组,皆出露于断层附近,且可见断层附近岩石矿物较周围蚀变强度明显偏高,表明含矿岩系严格受断层控制。对含矿岩系进行系统采样,测试了包括Au、TFe、As、Sb、Hg、U、Mn共7个指标。结果表明,各组分含量差异较大,以As最为显著,相关性分析结果印证了各组分含量的一致性和差异性。 |
| 英文摘要: |
| Taking the Fengdong Gold ore in Anlong county,Guizhou city as the research object,a detailed investigation of Fengdong surrounding geology and mineral resources, the strata exposed from top to bottom in turn three Triassic yongningzhen formation, lower Triassic Yelang three group, two Permian Longtan Formation, ore rock mainly occurs in the group are exposed in Yelang, faults, and visible near the fault rocks compared with surrounding alteration intensity was obviously higher, show that the ore bearing rock series is strictly controlled by faults. Systematic sampling of ore bearing rock series was carried out, including 7 indicators including Au, TFe, As, Sb, Hg, U and Mn. The results showed that the content of each component was different, and the As was the most significant. The correlation analysis confirmed the consistency and diversity of the main components. |
