近代大洋沉积中有两种一般类型的沉积海绿石:陆源他生海绿石和白生海绿石。大洋近代沉积主要含陆源他生海绿石(陆架和陆坡),这种海绿石是从海岸、岛屿和洋底的含海绿石的古代岩石来的。陆源他生海绿石的年龄为2到70百万年(根据取自大西洋的8个样品、太平洋的13个样品和印度洋的1个样品)。陆源他生海绿石的分布区与陆上含海绿石岩石的分布区恰好对应,但与气候和水深无关。近代大洋沉积中很少发现自生海绿石。含自生海绿石的沉积物构成了含有机碳、硫化氢和硫化物的近岸沉积物与洋底氧化沉积物(红粘土和其它沉积物)之间的过渡带。自生海绿石的分布区还不十分清楚。自生海绿石主要是在沉积物的成岩变化过程中由粘土矿物的蚀变作用和(或)间隙溶液的合成作用形成的。
There are two general types of sedimentary glauconites in modern ocean sediments: terrigenous terrigenous glauconites and white derived glauconites. Modern ocean sediments mainly include terrigenous epiphytic glauconites (shelf and slope), which originated from the ancient glauconitic rocks on the coast, islands and ocean floor. Luyuan He is born with glauconite from 2 to 70 million years (based on 8 samples taken from the Atlantic Ocean, 13 samples from the Pacific Ocean and 1 from the Indian Ocean). The distribution of terrigenous pyrochlore in Luyuan He corresponds exactly to the distribution area of plagioclase-bearing rocks on the land, but has nothing to do with climate and water depth. In modern ocean sediments rarely found spontaneous glauconite. Sediments with spontaneous glaucoma constitute the transition between near-shore sediments containing organic carbon, hydrogen sulphide and sulphide and oceanic oxide sediments (red clay and other sediments). The distribution area of authigenic glauconites is not yet clear. The authigenic glauconite is mainly formed by the alteration of clay minerals and / or the synthesis of interstitial solutions during the diagenesis of sediments.
