Chemical fingering printing of fluids in geological environments

流体构成地壳的一个组成部分，并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）、贱金属（Cu、Pb、Zn）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样品以亚显微特征（<5-20微米）的形式保存下来，称为流体包裹体。使用适当的设备，可以测量这些保存的流体的温度特性。测温数据允许一个重建的条件负责流体圈闭，因此，相关的矿化。由于其重要性，该技术被广泛用于经济地质领域，因为它可以直接测量成矿流体的性质。将这些数据与其他地质和地球化学约束相结合，导致开发了广泛用于矿产勘探的矿物存款模型。

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.
