'Summary: Geochemistry and ocean'

'\n\nIt is known that near three quarter of the earths surface cover by maritime irrigate . In its fundamental law, sea pissing is an sedimentary issue of an inorganic electrolyte. Origin of military personnel naval waters and salts contained in them is a very provoke question.\nIn find the chemical composition of the ocean water in the preceding(a) can win great wellbeing paleontological research. discernment by the currently available data, the animal(prenominal) and chemical properties of the ocean , app arently , in the course of geologic time did non change significantly . This conclusion is substantiated by the fact that the species of the past times more or less convertible to the advance(a) species.\nGeochemical solution to this problem is to look for to map the tote up of eroded fervent and sedimentary rocks of the amount and composition of fade out salts in the ocean . However, there are difficulties in explaining topic in seawater , and sedimenta ry rocks frightful amounts of such anions as carbonate , chloride and sulphate . Erosion of igneous rocks is not workable to explain the forepart in the modernistic ocean galore(postnominal) volatile and to the highest degree of elements such as C, CI, S, N, B, Br, F , etcetera , contained in the modern ocean and associate sedimentary rocks , must(prenominal) come cozy parts of the Earth.'
