| 摘 要： | 迄今为止文献中未见有铂矿原生晕研究的报道,通过对大岩子矿区地表和不同中段坑道原生晕的研究,发现在铂-钯矿体周围有清晰的F、Sb、Cd、Hg、As、Ag、Au、Pd、Pt、Cu、Ni元素的原生晕,其中F、Sb、Cd、Hg、As为前缘指示元素,Au、Ag为近矿指示元素,Pt、Pd、Cu、Ni为成矿指示元素.元素的垂直分带序列为(地表至矿体):(F、Sb、Cd、Hg、As)-(Ag、Au)-(Pd、Pt)-(Cu、Ni).地表岩石地球化学测量发现的Ⅲ号Pd、Pt异常带,具有多元素异常组合特征,判断为矿致异常,推测在该异常带下方可望找到隐伏矿体.坑道原生晕研究发现,在PD4中段出现浓集中心醒目、浓度分带清晰的F原生晕,推测在PD4中段下方可能存在新的盲矿体. |

| Abstract: | Based on the study on surface and tunnel primary halos, there exist primary halos ofPt, Pd, Ag, Au, Cu, Ni, As, Sb, Cd, Hg and F around ore bodies in the Dayanzi Pt - Cu deposit. Among them As, Sb, Cd, Hg and F are the front indicating elements, Au and Ag are the sub - ore indicating elements, and Pt, Pd, Cu and Ni are the ore - forming indicating elements. The vertical zoning sequence of primary halos in the Dayanzi Pt - Pd deposit from surface to bottom was F - Sb - Cd - Hg - As, Ag - Au, Pd - Pt, and Cu - Ni. The III anomalous belt of Pt and Pd was inferred to be a reflection of some ore bodies. The anomaly of F primary halo in the PD4 was inferred to be a reflection of blind ore bodies. |
