摘要
分带性是热液矿床重要特征，也是勘查与评价热液矿床的重要方法。为建立矿床完整轴向分带模式，需有矿体不同中段的化探样品分析数据。但对于产状较陡、深部工程少的矿体，要建立较准确的原生晕分带难度较大。以新疆红石金矿L1矿体1137 m、1080 m、1000 m和900 m的样品分析数据，分别采用“格氏”、“克氏”和“重心”法计算矿床轴向分带，再利用计算结果综合确定该矿床的原生晕分带模式。勘探验证表明，确定的分带模式与实际吻合性较好，是一种有效确定分带的方法。
Abstract
Zonation is an important characteristic and an important method to explore and evaluate hydrothermal depos-its. Complete zonation mode must been founded to predicate the deep and surrounding resource of mine, which require sample analysis data of different level. However, in some case, there has less engineering at early exploration. The steep-ly dipping ore bodies will result difficult to make sure the level location because of the apparent thickness of primary ha-lo and ore-body in drill hole. In this paper, author analized the sample of the different level of No.1vein in Hongshi gold deposit, adopts“Gregorian method”,“Kvyatkovsky method”and“barycenter method”to define the zonation mode of primary halo. The results are identical with the actual according to exploration. It is effective methods.
