玲珑金矿田岩石地球化学测量及其找矿效果

ROCK GEOCHEMISTRY SURVEY AND ITSAPPLICATION IN LINGLONG GOLD FIELD

摘要:

根据玲珑金矿田１∶２０００岩石地球化学测量结果，结合本区地质构造条件，初步总结了该矿田岩石地球化学特征。获取的岩石地球化学异常经过验证，施工的３５个钻孔有２７个见矿，４３条验证探槽中有４条发现工业矿体。该方法在发现隐伏的矿化蚀变带、寻找矿体（矿化体）、确定矿体剥蚀程度及指导钻探施工等方面均有明显效果。

Abstract:

ccording to the result of rock geochemistry survey in Linglong gold field on the scale of 1∶2000 and the condition of its geological structure,the rocks geochemical characteristics have been summarized. The obtained geochemical amonaly were examined by means of drilling and trenching. Among 35 holes drilled,27 reached orebodies and 4 trenches also reached orebodies among 43 trenches. This method is very useful in prospecting orebodies,determing ore denudation degreee,and guiding exploration design.
