摘　　要：本文以白马铁矿具有代表性的及及坪矿段为研究对象,对各矿层岩、矿石的主要共(伴)生成矿元素分布特征进行了研究。结果表明:白马铁矿及及坪矿段中各共(伴)生元素的富集系数、变异系数明显不同,反映各元素的富集、分异存在较大差异,含矿岩体中共(伴)生元素Cr、Ni富集程度高,变异系数大,在有利部位可能富集成矿,具有一定的找矿潜力。共(伴)生成矿元素可根据其同源性分为两个元素组合,分别为TFe、Ti、V、Co元素组合和Ni、Cu元素组合,7种共(伴)生成矿元素浓度偏离正态分布且峰值位置不同,反映了白马含矿岩体有成矿岩浆的多期多阶段补给叠加的特点。Taking the representative Jijiping ore section of Baima Iron Mine as the research object,the geochemical characteristics of the main associated mineral elements of each ore strata are studied.The results shows that the enrichment coefficient and differentiation coefficient of each associated mineral element in Jijiping ore section of Baima Iron Mine are obviously different,reflecting that there are great differences in the enrichment and differentiation of various element,the ore-bearing rock mass has a high degree of Cr and Ni enrichment and a large coefficient of variation,which may be enriched and ore-forming in the favorable position and has a certain prospecting potential.The co-associated ore-forming elements can be divided into two assemblages according to their homology,namely,Tfe,Ti,V,Co metallogenic assemblies and Ni and Cu metallogenic assemblies.The difference between the concentrations deviation from normal distribution and the peak positions of these 7 associated mineral elements reflects the Baima ore-bearing rock mass has the characteristics of multi-period and multi-stage recharge superposition of metallogenic magma.
