Chemical fingering printing of fluids in geological environments

流体是地壳不可分割的一部分，参与许多重要的过程，包括形成热液矿产资源，如贵金属(Au、Ag、PgeS)、碱金属(铜、铅、锌)和高科技金属(Ta、Nb、W、Sn)。重要的是，数百万年前曾经存在的这种流体的样本以亚微观特征(5-20微米)的形式保存下来，称为流体包裹体。有了适当的设备，就有可能测量这些保存下来的流体的温度性质。测温数据使人们能够重建导致流体捕获的条件，从而重建相关的矿化作用。由于其重要性，这项技术被广泛应用于经济地质领域，因为它可以直接测量成矿流体的性质。这些数据与其他地质和地球化学约束条件的集成导致了在矿产勘探中广泛使用的矿床模型的发展。

Fluids constitute an integral part of the earth's crust and are involved in many important processes, including forming hydrothermal mineral resources such as precious- (Au, Ag, PGEs), base- (Cu, Pb, Zn) and high-tech (Ta, Nb, W, Sn) metals. Importantly, samples of such fluids once present millions of years ago are preserved in the form of submicroscopic features (<5-20 microns) called fluid inclusions. With appropriate equipment, it is possible to measure the thermometric properties of these preserved fluids. The thermometric data permit one to reconstruct the conditions responsible for fluid entrapment and, hence, the associated mineralization. Because of its importance, this technique is widely used in the field of economic geology, as it allows direct measurement of the properties of ore-forming fluids. Integration of this data with other geological and geochemical constraints leads to development of mineral deposit models widely used in mineral exploration.
