摘要
成矿作用要经历漫长而复杂的地质过程,生物作用的地质效应将受到不同程度的改造,特别在经受强烈变质和热液叠加的矿床中,生物作用的信息更加微弱。因此,在应用生物标志判别矿床成因时,必须进行矿石的生物结构、有机碳质物、矿物有机包裹体成分、生物标志化合物和稳定同位素组成诸方面的研究,并绍合地质坏境条件的综合分析,探讨金属矿床的生物及衍生物的成因标志。
The ore-forming process is both prolonged and complicated, some geological effects of the biological activities might be altered in the process,especially in some ore deposits formed by intense metamorphism or byhydrothermal superimposition less biological information can be remained.So it is necessary to make some studies on biostructures of ores, consti-tuents of organic inclusions and biomarkers and make a thorough inquiry onbiogenic (derivative) marks of metallic ore deposits on the condition of somecomprehensive analyses about paleogeological environments when the bioge-nic marks are applied to distinguishing the genesis of ore deposits.
