摘要
热液岩是指由热液（气水热液的总称）中结晶出来的矿物所组成的岩石．热液岩是在热液的形成过程中，或是在热液的运移过程中，萃取了先存岩石中的成分，并将其运移到了一定的空间（断裂的裂隙、褶皱的虚脱部位等），由于热液的压力、温度、ｐＨ值及其他物理化学条件的变化。
ydrothermal rock is consisted of minerals formed by crystallization in hydrothermal solution.As magmatic rock,sedmertary rock and metamorphic rock,hydrothermal rock is a kind of independent rock.Hydrothermal rock is different from sedimentary rock formed by chemical action, e.g., in sloution temperature and genetic environment.Hydrothermal rock is formed in hydrothermal solution and space within rocks (e.g.fissure),while sedimentary rock is formed in normal temperature and deposit basin.The difference between hydrothermal rock and magmatic rock is that magmatic rock is the product of magma through cooling and coagulation.Hydrothermal rock is not influenced by metamorphism,that is different from metamorphic rock.Hydrothermal rock is more closely related to metasomatite.The main difference is that all minerals for hydrothermal rock are derived from hydrothermal solution,while metasomatite is formed by the metasomatism of hydrothermal solution with wall rocks.
