浙江天台大岭口银铅锌矿床异常结构研究
|
摘要
以浙江天台大岭口银铅锌矿床为试验矿区,通过系统研究矿床典型剖面、平面和中段主要成矿元素Ag、Pb、Zn矿化富集特征与岩矿石中其它元素富集或贫化的相关性,进行地球化学异常结构研究,以此为基础进一步探讨了深部矿体预测方法技术。研究发现,这种相关性及其所确定的元素组合分类对于矿体位置、矿化程度和成矿环境条件等具有指示意义。
通过研究典型剖面、平面和中段上元素的异常结构,探讨富集和贫化两类元素在水平方向上的结构关系,进一步筛选了能够反映矿床矿体产出位置、矿化程度等有针对性的地球化学勘查指标,进而提出了以异常结构特征为基础的深部矿体预测方法。
本文是通过查明矿床中的元素地球化学异常结构特征对深部矿体进行预测的一个尝试,此项研究成果为热液型银铅锌矿床地球化学勘查提供了新的案例。
As a test area, Dalingkou Ag-Pb-Zn deposit, which located in Tiantai, Zhejiang province was systematically reserched on the correlation between the main ore-forming elements’mineralization and enrichment characteristics, such as Ag, Pb and Zn, and enrichment or depletion of other elements in rocks and ores of a typical profile, a plane and middle sections. In addition, the structure of geochemical anomaly also was detailedly studied. Based on above studying results, the deep ore-body prediction method and technology were tentatively discussed furtherly. Result showed, the correlation and elements combination and classification caused by the correlation could direct the ore-body location, mineralized degree and conditions of metallogenic environment.
By the study on the structure of elements geochemical anomaly in the surface rocks of a typical profile, a plane and middle sections, the structure relationship of two kinds of depleted and enriched elements at horizontal direction was discussed. Furthermore, the geochemical exploration indexes that could reflect the ore deposits location and the mineralized degree were determined for further. Then, methods of predicting deep ore-body, which based on the structural feastures of geochemical anomaly, were put forward.
This paper is an attempt to predict deep ore body by studying on the deposit’element geochemistry anomaly structure features. Besides, the results also provides a new and successful case suitable for the hydrothermal type of Ag-Pb-Zn deposit geochemical exploration in the future.
