流体晶、流体晶矿物组合、流体岩及其研究意义

流体是地球各圈层之间相互作用的纽带，在成岩、成矿过程中起着十分重要的作用。目前，流体的研究主要集中在流体对先存矿物岩石进行的交代作用方面，而对流体直接结晶形成的矿物领域研究较少。文中根据作者近几年的研究成果对从流体直接结晶而成的矿物——流体晶以及流体晶矿物组合、流体岩等的定义、特征进行了归纳总结。最新的研究结果显示：岩浆中可以含有大量的流体，这些流体来源既可以是岩浆演化富集、岩浆与围岩相互作用产生，亦可以是外部来源。因此，流体晶矿物、流体岩在自然界应该是普遍存在的。流体晶矿物的提出将深化人们对地质过程的理解，发展岩石学及矿床学的研究新领域，有利于矿床勘探和成矿预测。

Fluid minerals,mineral assemblages,fluid rocks: significance in the studies of rocks and ore deposits.

Fluids play a key role in the origin of rocks and ore deposits. They are the connecting media for the interaction between different Earth layers. Currently in fluid research, most geologists mainly study fluid alteration of existing minerals and rocks while a few geologists pay attention to minerals crystallized from fluids. In this paper, we present the definition and characteristics of fluid minerals, mineral assemblage and fluid rocks based on many years of research. Our recent study shows that magma may contain large amounts of fluids, originated from fluid concentration during magma evolution, magma-country rock interaction or external sources. Putting forth the concept of fluid mineral shall deepen our understanding of geologic processes hence develop new frontiers in petrologic and ore deposit research. The concept can be useful in mineral exploration and metallogenic prediction.
