玲珑金矿大开头矿区Bi特征及指示意义

在金矿床中,金、铋常常相伴产出,在金矿体周围存在明显的铋异常,它可作为重要的指示元素。笔者研究了玲珑金矿不同岩石中铋与金含量之间的关系,比较了基岩地球化学剖面中两元素的相关性,采用电子探针分析了主要矿石矿物中铋和金的含量,发现不同类型岩石中铋含量差异明显,铋在矿体中含量远高于围岩,在矿区中铋与金呈幂函数正相关,铋原生晕规模大、衬度高,与金都是以独立矿物相形式存在。在玲珑金矿化探找矿中,铋含量高,与金呈较好的正相关关系,是最佳指示元素之一。     

综合物探方法在焦家断裂带南延中的应用

焦家断裂带是山东省胶西北金矿集中区主要的成矿断裂之一,该断裂带南部被第四系严重覆盖,多年探索研究未果。此次利用高精度磁测、视电阻率联合剖面、CSAMT及SIP等多种物探方法,结合区内成矿地质条件,推断出焦家断裂带南延部分隐伏断裂分布情况,即在黄家附近向北至徐村院为一条断裂带(F1),向南分为三条断裂带(F1、F8和F9),其中F1为主断裂,F8、F9为其次级断裂。经钻探验证与物探推断的焦家断裂带南延部分相吻合,为该区下一步金矿勘查提供了找矿方向。

磁铁矿中微量元素和铂族元素的组成特征

文章分析了磁铁矿中铂族元素(PGE)含量的特征,发现磁铁矿中铂族元素富集为10-9级,主要为PPGE(即Pd,Pt,Rh)。富集PPGE的主要原因是其在热液活动的晚期阶段可以被轻微的再分配和富集,其含量的高低严格受岩浆结晶过程中氧逸度的控制。磁铁矿的结晶程度直接影响岩浆体系的氧逸度,控制了PGE的含量分布,进而影响成矿。
