引言对内华达卡林地区产在碳酸盐中的浸染型金矿的地质学、矿物学、流体包裹体、地球化学和稳定同位素的综合研究(Rodtke 等,1980)表明,成矿作用及以后的大量氧化作用与发生在浅层的、可能被下伏第三纪火成活动所驱动的天水热液体系事件有关。对内华达科特斯矿床较早的粗略研究表明(Rye,1974等),其矿化与卡林矿床尽管在时代、构造背景及地球化
INTRODUCTION A comprehensive study of the geology, mineralogy, fluid inclusions, geochemistry and stable isotopes of disseminated gold-bearing carbonates produced in the Carlin area, Nevada (Rodtke et al., 1980) showed that mineralization and subsequent Massive oxidation is associated with the event of the Tianshui hydrothermal system, which occurred in the shallow layer and may be driven by underlying Tertiary igneous activity. The earliest rough studies of the Cortez deposit in Nevada show that (Rye, 1974, et al.) That its mineralization and Carlin deposit despite the age, tectonic setting and geochemistry
