摘要
东至兆吉口铅锌矿床发现于2005年区调工作中,后经小范围普查、详查工作对矿区内铅锌矿体的形态、产状、规模等进行了详细勘查,累计查明铅锌总金属量达大型铅锌矿床规模,并估算了伴生金、银、铜金属量若干,具有较好的开发利用价值。在此期间,激电测深方法的使用及其成果的推断解释,对该矿床的发现和扩展起到了关键性的作用,其不仅有效地指示了浅部铅锌矿体的赋存地段,而且对矿床的的形成机制的研究提供了理论的依据,指导了矿区勘探工程的布置,实现了较大的经济效益。
The Zhaojikou lead-zinc deposit,Dongzhi was discovered in a regional survey conducted in 2005.The followup small-area general and detailed survey on its form,occurrences and size upgraded it to a large scale in terms of total amount of metals of lead and zinc.The amount of associated gold,silver and copper was estimated,which exhibit good values for development and utilization.During the survey period,the use of IP sounding and its results-based inference and interpretation played a pivotal role in discovering the deposit and its extension,it not only effectively indicated the shallow Pb-Zn orebody occurrence area,also provided theoretical basis for studying the mechanism for the deposit to form,and guided the arrangement of exploration engineering in the mineral district,and achieved great economic benefit.
