世界各国历来对金矿的开发和研究十分重视,特别是近年来在金矿地质工作和成矿理论研究方面都有明显的进展,但对金矿床的成因分类尚有不同认识。 近几年来,笔者在研究下扬子区金属矿床的同时,注意到一种在区域内较稳定产出、受海底热事件控制的金矿床新类型——“沉积—海底喷出沉积—热液变质改造”成因(Cu、S)金矿床(以下简称“海底喷出沉积”金矿床)。本文特对这种类型的金矿床作些扼要的阐述。
All countries in the world have always attached great importance to the development and research of gold deposits. In particular, significant progress has been made in the geological work and mineralization research of gold deposits in recent years. However, there are different understandings on the genesis classification of gold deposits. In recent years, while studying the metallogenic deposits in the lower Yangtze region, the author noticed a new type of gold deposit that is more stable in the region and controlled by seafloor thermal events- “Sedimentary-Submarine Sedimentary Sedimentary-Hydrothermal Modification Transformation ”genesis (Cu, S) gold deposit (hereinafter referred to as“ seabed discharge deposition ”gold deposit). This article provides a brief overview of this type of gold deposit.
