金矿系统矿床地质特征与流体包裹体特征——造山型金矿床为例

Geological Characteristics and Flued Iinclusion Characteristics of Gold Deposits in Gold Deposits System——Case Study of Orogenic Gold Deposits

成矿流体与成矿作用之间的关系,一直以来是地质学界研究热点之一。从流体包裹体研究中我们可以获得当时成矿环境和物理化学条件(温度、压力、成分等)。目前,流体包裹体研究手段已经广泛应用于各类热液矿床,并且积累了大量研究数据。它们对成矿环境、流体演化和矿质沉淀特征都具有重要指示作用,能够反映成矿物化条件及成矿过程,因此具有重要的理论研究意义。由于实际工作中,地质特征和流体包裹体特征可能存在矛盾,为此,需要更好的建立矿床地质与流体包裹体之间的衔接,以便更好开展地质找矿工作。

The relationship between ore-forming fluids and mineralization has always been one of the hotspots in the field of geology.From the study of fluid inclusions,we can get the metallogenic environment and physicochemical conditions(temperature,pressure,composition,etc.).At present,fluid inclusion research methods have been widely used in various hydrothermal deposits,and a large number of research data have been accumulated.They are important indicators of metallogenic environment,fluid evolution and deposit characteristics,and can reflect mineralization conditions and metallogenic process,so they have important theoretical significance.Because there may be contradictions between geological characteristics and fluid inclusion characteristics in practical work,it is necessary to establish a better connection between ore deposit geology and fluid inclusion in order to better carry out geological prospecting work.
