喷流沉积(SEDEX)型矿床具有极高的经济价值和研究意义。然而,由于该类矿床的流体包裹体太小而难以研究及矿化常常受到后期变形变质作用改造(Wilkinson,2014),现阶段,对其流体的来源、演化以及成矿模式的认识不够深入。近年来,越来越多研究者认识到海底同生交代作用及渗滤作用对于该类矿床的成矿有重要作用(Leach,2010;Wilkinson,2014)。黄铁矿在该类矿床中含量虽然不高,但却记录了不
SEDEX deposits have very high economic value and research significance. However, the fluid inclusions of this type of deposit are too small to study and mineralization is often modified by later deformation and metamorphism (Wilkinson, 2014). At this stage, their understanding of fluid source, evolution and metallogenic model is inadequate. In recent years, more and more researchers have realized that submarine metasomatism and diafiltration play an important role in the mineralization of this type of deposit (Leach, 2010; Wilkinson, 2014). Pyrite in this type of deposit in the content is not high, but did not record
