摘要
本次研究介绍了构造地球化学测量理论的发展历程、研究现状及其应用效果,同时基于项目组在基岩区进行的找矿勘查实践,总结提炼最新研究成果和认识,提出了构造地球化学弱信息提取方法,并与传统的地球化学测量方法相对比,指出传统测量方法的局限性和构造地球化学弱信息提取方法的优越性。其次,系统归纳总结了构造地球化学弱信息提取方法的理论基础、工作条件、布点方法、采样原则、采样介质、异常解读和成图及其应用,重点突出构造地球化学弱信息提取方法中布点方法的合理性、采样点布置的代表性、采样介质的多样性、样品和元素异常信息的有效性(“有”和“无”),在此基础上构建构造地球化学弱信息提取方法指标体系。最后结合黔西南卡林型金矿分布区之灰家堡背斜东段找矿预测实践,认为构造地球化学弱信息提取方法较之传统的构造地球化学测量能够更加有效地提取深部成矿弱信息,在热液矿床隐伏矿找矿工作中具有较好的应用前景,可以推广到所有的基岩区热液矿床隐伏矿找矿预测工作中去。
This study introduced the development process,research status,and application effects of the tectono-geochemistry survey theory,and proposed the tectono-geochemistry weak information extraction method by summarizing the latest research results and understandings based on the prospecting practice in bedrock areas.Based on the contrastive analysis,this study pointed out the limitations of the conventional geochemical survey methods and the advantages of the tectono-geochemistry weak information extraction method,which was developed from the conventional tectono-geochemistry survey method.Moreover,this study systematically summarized the theoretical basis,operating conditions,deployment method,sampling principle,sampling media,anomaly interpretation,mapping,and application of the tectono-geochemistry weak information extraction method,highlighting the rationality of the deployment method,the representativeness of sampling points,the diversity of sampling media,and the validity(“yes”and“no”)of element anomalies and samples.Based on these,this study established the index system of this method.Finally,by combining the prospecting prediction of the eastern section of the Huijiabao anticline in the distribution area of Carlin-type gold deposits in southwestern Guizhou,this study concluded that the tectono-geochemistry weak information extraction method can extract the deep metallogenic weak information more effectively than the conventional tectono-geochemistry survey.It also inferred that this method has a good application prospect in the prospecting of concealed hydrothermal deposits and can be applied to the prospecting prediction of concealed hydrothermal deposits in all bedrock areas.
