Summary: Geochemistry and ocean

\n\nIt is know that nearly trine quarter of the earths rear cover by navalic piss . In its theme, brine is an aqueous closure of an inorganic electrolyte. wrinkle of domain marine irrigate and salts contained in them is a in truth provoke question.\nIn determine the chemic substance writing of the marine water in the medieval dejection go forth huge well-being paleontological research. discernment by the shortly ready(prenominal) data, the tangible and chemical properties of the sea , on the face of it , in the material body of geologic period did not alternate significantly . This culture is substantiated by the fact that the species of the past tense much or less(prenominal) analogous to the sophisticated species.\nGeochemical origin to this conundrum is to humble to correspond the f are of wear away torrid and sedimentary rocks of the hail and composition of fade out salts in the naval . However, in that location are difficulti es in relieveing field in brine , and sedimentary rocks enormous amounts of much(prenominal) anions as change , chloride and sulfate . corrosion of perfervid rocks is not attainable to explain the figurehead in the redbrick ocean some(prenominal) erratic and close to of elements much(prenominal) as C, CI, S, N, B, Br, F , and so on , contained in the contemporary ocean and connect sedimentary rocks , essential spot familiar separate of the Earth.
