在由单个热液金属矿床的生物—有机质成矿作用研究向区域生物—有机质成矿系统深入的今天 ,分子化石的重要性和复杂性日益显得突出。热液金属矿床成矿带往往属于有机质的过成熟区 ,分子化石的存在首先要考虑成矿后迁入事件的叠加 ,从中排除某些生物成矿作用假象 ,如川甘陕金三角区。除了最常见的吸附有机质外 ,晶包有机质可以是有机质过成熟的金属成矿区分子化石的一种不可忽视的新来源 ,可提供流体源或矿源的信息 ,如长江中下游多金属成矿区。赋矿岩与蚀变岩之间的某些分子化石差异则蕴含着与成矿有关的诸如还原作用等化学反应信息 ,如长江中下游多金属成矿区。
Nowadays, the importance and complexity of molecular fossils are becoming increasingly prominent today, from the study of bio-organic mineralization in a single hydrothermal metal deposit to the deepening of regional bio-organic mineralization systems. The hydrothermal metallogenic metallogenic belt belongs to the overriding region of organic matter. The existence of molecular fossils must first consider the superimposition of migration events after mineralization, and exclude the illusion of some biogenic mineralization, for example, the golden triangle of Sichuan, Gansu and Shaanxi provinces. In addition to the most commonly adsorbed organic matter, the crystallized organic matter can be a new and undeniable source for molecular fossils of organic overripe metallogenic regions and provide information on fluid or mineral sources, such as the polymetallic mineralization in the middle and lower reaches of the Yangtze River. Some molecular fossil differences between ore-hosting rocks and altered rocks contain chemical reaction information related to metallogenesis such as reduction, such as polymetallic metallogenic regions in the middle and lower reaches of the Yangtze River.
