【Abstract】 Sixteen ultrabasic rock units with different ore-bearing propertieshave been found in the Lengshuiqing area. On the basis of a discriminantanalysis of the contents of the mineralization elements Cu,Ni,Co,therock units are classified into two groups: ore-bearing and non-ore-bearing.The rock units No.Ⅰ,Ⅱ,and Ⅲ belong to the ore-bearing group andhost ore bodies; No Ⅸ contains some ore minerals only, while No. Ⅶ, Ⅻ,and XV are bare rock.更多还原
