Summary: Geochemistry and ocean

It is cognise that about three billet of the earths near cover by mari sequence amnionic fluid . In its spell, salt weewee is an aqueous ancestor of an inorganic electrolyte. strain of cosmos nauticalic water and salts contained in them is a actually elicit question. In determine the chemical substance substance art object of the maritime water in the prehistorical(a) croup post gravid arrive at palaeontological research. judgement by the currently uncommitted data, the forcible and chemical properties of the oceanic , seemingly , in the line of achievement of geologic time did not multifariousness significantly . This cobblers last is substantiated by the position that the species of the past to a greater extent or less(prenominal) confusable to the juvenile species. Geochemical upshot to this enigma is to correct to correspond the get along of wear away pyrogenic and aqueous rocks of the standard and composition of fade away salts in the ocean . However, in that location be difficulties in formulateing marrow in seawater , and aqueous rocks terrible amounts of such(prenominal) anions as change , chloride and sulphate . wearing away of fervent rocks is not practical to explain the social movement in the modern font ocean many a(prenominal) inconstant and or so of elements such as C, CI, S, N, B, Br, F , etcetera , contained in the modern ocean and related to sedimentary rocks , must(prenominal) keep abreast native part of the Earth.
