摘要
以新疆东天山石英滩金矿为例,研究危机型矿山资源评价与预测的理论和方法,以期为地质工作者进行危机型矿山资源评价工作提供思路。已知矿床石英滩金矿与其外围预测区东北夼在成矿条件、控矿构造及岩石地球化学特征等方面有很大的相似性,因此采用相似类比理论对预测区进行资源评价。根据已掌握的石英滩金矿床原生晕叠加模式,建立已知矿床的地球化学评价指标,并利用这些指标对异常区东北夼进行成矿预测。结果表明,预测区地表原生晕为前缘的概率是60%,为中部的概率是40%,由此判断深部有隐伏矿的可能。
This paper, based on a case study on Xinjiang＇s Shiyingshan gold deposit, studies the evaluation and forecast theory and methods in resources-crisis mines, aimed at helping geologists work in such mines. Shiyingtan gold deposit is quite similar with Dongbeikuang area, located in its adjacent area, in mineralization, ore controls and geochemistry; hence a similarity analogy is applied to evaluate its resource potential. From Shiyingtan＇s gold halo overlapping mode, geochemical index is established to forecast Dongbeikuang＇s gold mineralization. The results show a possibility 60% in its front ground halo, 40% in its middle, which may reveal a hidden gold mineralization.
