| 摘 要： | 在分析限定矿源岩含义的内外在因素的基础上,结合桂西北地区具体地质条件和资料,提出了一些研究矿源岩的新方法:岩石孔渗性及微裂隙研究法、成矿元素及其相关元素增亏检验法、成矿温度与地热场温对比分析法等。新的研究结果否定了桂西北地区微细粒浸染型金矿的矿源来自围岩(中三叠统)的认识。

| Abstract: | The idea and methods to identify the source rock have been mainly to study the similarity among some constituents, such as microelements and isotopes of ore, vein, host rock and presupposed source rock. The author presents some new methods in this paper to recognize source rock: porosity-microfracture volume ratio-permeability research, gain and loss check for minerogenic elements and associated ones, comparative analysis to ore-forming temperature with the temperature of geothermal field. The analysis results with these methods show that the ore source didn't originate from the host rock (the Middle Triassic) in gold deposits northwest Guangxi. |
