矿床原生晕的垂直分带研究是寻找隐伏矿体和盲矿体的有效方法之一。本文通过对 30余种元素的分析 ,研究元素的分带指数、变化系数和变化指数梯度差 ,由此得出矿床原生晕由上至下的垂直分带为 :Mn Cd Zn Sn Cu Au Hg As( 1 82 0中段 ) ;Bi W Co Sb( 1 730中段 ) ;Mo Y( 1 70 0中段 ) ;Ni V Nb Sr La Sc Ti Yb Be Ag( 1 6 4 0中段 ) ;Pb Ga B Ba( 1 5 2 0中段 )。 30种元素的分带序列为 :Mn Ag1 Pb1 Cd Zn Sn Cu Au Hg As Bi W Co Sb Mo Y Ni V Nb Sr Cr La Sc Ti Yb Be Ag2 Pb2 Ga B Ba。
The study of vertical zonation of the primary halo of the deposit is one of the effective methods to find the hidden ore bodies and blind ore bodies. In this paper, the analysis of more than 30 kinds of elements to study the elements of the zonation index, coefficient of variation and gradient index difference, which derived from the primary deposit vertical halo from top to bottom: Mn Cd Zn Sn Cu Au Hg As (Middle of 1 82 0); Bi W Co Sb (middle of 1 730); Mo Y (middle of 1 70 0); Ni V Nb Sr La Sc Ti Yb Be Ag Mid section). The zonation sequence of the 30 elements is: Mn Ag1 Pb1 Cd Zn Sn Cu Au Hg As Bi W Co Sb Mo Y Ni V Nb Sr Cr La Sc Ti Yb Be Ag2 Pb2 Ga B Ba.
