| 摘 要： | 矿物晶体形态标型研究广泛应用于矿床成因研究和成矿预测工作,是成因矿物学研究中一个很重要的方面。文章以黄铁矿晶体形态统计为例,介绍了适用于简单晶体形态统计的形态统计法、适用于复杂晶体形态统计的习性统计法,以及根据实际观测实践提出的权重统计法。通过对这3种方法的比较,指出了不同方法的利弊,给出了根据不同研究目的及样品实际情况选择不同方法的建议。

| Abstract: | Typomorphic characteristics of mineral crystal form are widely used in the genetic study of mineral deposits and metallogenic prognosis. It is a very important research direction of genetic mineralogy. Taking the pyrite crystal as an example in this paper, the authors introduce three statistical methods of mineral crystal forms. The first one is for simple crystal forms called Form Statistical Method. The second is for complex crystal forms called Habit Statistical Method. And the last is an improved one called Weight Statistical Method. Comparing the three methods, the authors point out the advantages, disadvantages and put forward some suggestions that selection of the methods should be based on different research purposes and the situations of samples. |
