现代海洋沉积物中的矿物主要可分成两大类:即自生矿物及陆源矿物。 自生矿物:在现代海洋环境中由各种作用(如化学作用、生物—化学作用等)所形成的新生矿物,通称自生矿物。它是一种指相矿物,可以反映沉积环境的物理、化学条件。海洋是形成自生矿物的天然宝库。海洋沉积物中最典型的自生矿物如海绿石、磷钙石、锰结核、钙十字沸石等。 陆源矿物:大陆剥蚀区母岩风化后由各种营力(如河流、波浪、海流和风等)搬运入海的原生矿物,通称陆源矿物。它是蚀源区的标志,
The minerals in modern marine sediments can be divided into two major categories: authigenic and terrigenous minerals. Authigenic minerals: new minerals formed by various functions (such as chemical action, bio-chemical action, etc.) in the modern marine environment, commonly called authigenic minerals. It is a phase-mineral that reflects the physical and chemical conditions of the sedimentary environment. The ocean is a natural treasure trove of authigenic minerals. The most typical marine minerals in the sediments such as glauconite, phosphorite, manganese nodules, calcium Phillipsite and so on. Terrigenous minerals: The denuded areas of the mother rock weathered by the various campuses (such as rivers, waves, currents and winds, etc.) to carry the original minerals into the sea, commonly known as terrestrial minerals. It is a symbol of the source area,
