摘要

为了加强区域和矿床地质工作的定量化预测,利用上黑龙江盆地内砂宝斯和宝兴沟2个大型岩金矿床的已有勘探成果,在元素立体分散模式的基础上,结合成矿可利用金属分量立体评价模型和方法,对这2个矿床进行定量评价,指出宝兴沟矿区、八里房矿区和十五里桥矿区的期望勘探资源量。同时,在具体应用定量评价方法的过程中提出了“成矿块体”概念,即异常圈定范围内向下垂深500 m的地质体范围。通过对砂宝斯和宝兴沟矿床的评价计算,证实“成矿块体”才能更好评价和预测矿床的规模和储量。

Abstract

In order to strengthen quantitative prediction for regional and geological work,based on the dimension geochemical dispersion patterns,combined with ore forming body evaluation model and method for available metal component,using the exploration results of Shabaosi and Baoxinggou gold deposit,the two large-scale gold deposits in Heilongjiang Basin,to conduct a quantitative evaluation.The results point out the expectation exploration resource for Baoxinggou area,Balifang area,and Shiwuliqiao area.We also proposed the concept of block of formation ore in the specific application of quantitative assessment method,namely the anomaly within the range of drop 500 meters deep geological range.And through the evaluation of the Shabaosi and Baoxinggou deposit calculation,confirmed that block of formation ore can evaluate and predict the deposit scale and reserves better.
