计算和确定矿床原生晕指示元素垂向分带序列是地球化学找矿研究特别是矿床原生晕分析和研究的重要内容之一,国内、外地学者提出了多种计算方法。这里介绍几种常用的计算方法:分带指数法、广义衬值法、浓集重心法、浓集指数法、比重指数法、含量梯度法等,并指出这些方法的优点和不足,认为计算矿床原生晕指示元素垂向分带序列时,不宜采用传统的格里戈良分带指数法,而应采用广义衬值法、浓集重心法或比重指数法。

Computing and determinating of vertical zoning sequence of indicator elements for a deposit is one of important re-search contents on geochemical exploration,especially on primary halos of a deposit.Many computing methods on it have been proposed by geochemists at home and abroad.The common computing methods are introduced in this paper such as the Grego-rian's zonality index method;the generalized contrast value method;the concentrated barycenter method;the concentrated in-dex method;the proportion index method;element concentration gradient method and so on.The advantages and disadvantages of these methods are summarized.It is concluded that the Gregorian's zonality index method,which is a taditional method,is inappropriate and the generalized contrast value method;the concentrated barycenter method and the concentrated index method should be used to determinine the vertical zoning sequence of indicator elements about primary halos for a deposit.
