黄金是贵金属元素,在矿床中的分布不均匀.各国地质学家都在研究金的分布规律.南非地质学家研究了24个大型含金砾岩矿区,认为符合三参数对数正态分布.苏联地质学家研究了60个砂金矿区,认为附合指数规律.我国现在规范中都采用品位变化系数来研究金矿的不均匀程度,实际上是采用了正态分布的系数来研究非正态分布的规律.因此用什么样的参数表示一个金矿床的特点是值得讨论的问题.
Gold is a precious metal element, distributed unevenly in the deposit.Geologists from all over the world are studying the distribution of gold.The South African geologists have studied 24 large gold-bearing conglomerate rocks and considered the three-parameter lognormal distribution.The Soviet Union geology The study of 60 gold and gold mining area, that the law of coherence index.Now China now regulate the use of grade variation coefficient to study the degree of non-uniformity of the gold mine, in fact, is the use of the normal distribution coefficient to study the non-normal distribution Therefore, what kind of parameters are used to represent the characteristics of a gold deposit is a question worth discussing.
