中文摘要:通过对粤北典型钨矿,尤其是棉土窝钨矿矿脉各中段成矿元素全面系统的含量统计分析,得出其主要矿脉成矿元素的空间分布规律从下至上依次为Mo-W-Cu(Sn)-Pb、Zn-Ag,Mo主要在矿脉的下部富集;而W的含量自上而下有下降的趋势;Cu的主要富集部位显然是在矿脉的上部;Pb、Zn、Ag则多已剥蚀殆尽,仅在地表残积土中少量富集。棉土窝钨矿矿脉各中段Mo随着矿脉深度的增加富集程度也随之增加。
Abstract:Based on the evidence from the tungsten deposits including the time-space relationship between the ore veins and their country rock strata, ore-forming element assay value of different altitude, the main findings show that the ore forming elements in an ore-bearing quartz vein usually displays zoning characteristics, that is, element Mo used to deposit first, then W, then Cu, and finally Pb/Zn/Ag from the bottom of ore vein upwards, in good agreement with that clarified by the Geochemical Field of Elements (GFE).
