| 中文摘要: |
| 贵州三都地区发现许多汞、金、锑、铅锌矿床(点),在以往地质工作对矿床地质特征、成矿规律及矿床成因认识基础上,通过遥感、物探、化探方法对各矿床(点)间的空白带开展地质找矿工作,在下排正地区发现了金锑矿体。下排正地区金锑矿产于F33断层上盘,围岩为上寒武统三都组一段(∈3s1)条带状灰岩,蚀变有黄铁矿化和毒砂化;综合分析发现,该区具有较大的金锑矿找矿潜力。 |
| 英文摘要: |
| In Sandu district are discovered many Hg,Au,Sb and Pb-Zn ore occurrences and deposits.Based on understanding of the previous geological data and summary of ore-forming law and Genesis of the deposits remote sensing data interpretation,geophysical exploration and geochemical survey are conducted at blank areas between the occurrences and deposits for ore prospecting and new Au-Sb ore bodies are located in the banded limestone of the 1st member of Sandu formation (∈3s1) of Upper Precambrian Series at upper plate of fault F33.Alteration includes pyritization and arenopyritization.Comprehensive analysis of remote sensing interpretation,geophysical and geochemical data shows potential for prospecting Au,Sb ore deposits in the district. |
