Geochemical

Geochemical science is a branch of chemistry that is used to solve a variety of problems as well as to understand the terrestrial earth and how the earth works (wm white, Geochemistry, 2007). Another source also said that the geochemical character to learn the science of chemical species on the earth and its evolution throughout the history of the earth. certainly there are many other definitions concerning geochemistry, but the two images above have been fairly represented. geochemical itself consists of various sub-topics (or derivative) is actually fixed to each other mutual respect, there is no division that really separate.

Before time friends know more and more about what geochemical itself, let us equate the first frame we think that this geochemical coming from the two disciplines namely geology and chemistry, not only the incorporation of science, but it is a discipline that helps to explain the phenomenon geological lasts or the earth as seen from the chemical. nah, therefore, we certainly must know and understand the science geoligi first, but the science of geology itself consists of many branches, too, one of them: mineralogy, petrology, sedimentology, geomorphology, paleontology, geologic structure, stratigraphy, and others. after that then we can more easily know and understand about geochemistry. Okay, if we have the same frame please continue reading.
First of all of course we can all wonder, what the heck geochemical it?, geochemical learn the science content of elements and isotopes in the Earth's composition, especially related to abundance (abundant), the spread and control laws. growing part of the basic branches of the geochemical geochemical including geothermal, mineral geochemistry, petroleum geochemistry and environmental geochemistry. the study after the author can review more about mineral geochemistry, especially in sedimentology.

Geochemical birth as a new branch of geological science gives rise to a new method and observation data on a variety of subject that a lot of attention to some experts sedimentology. some of the geochemical studies initially focused on quantitative research to know the spread of chemical elements in nature, accounting for its distribution in sedimentary rocks. the longer the data led some experts to understand what is being said as the geochemical cycles (geochemical cycle) and the discovery of the laws that control the deployment of elements and processes that lead to the emergence of patterns of spread elements like that.Recently, nuclear chemistry (nuclear chemistry) contribute something "hour" and "thermometer" which in turn opens up a new era of research in the sediments. radioactive elements, especially 14c and 40k, so maybe doing the dating method immediately on specific sedimentary rocks. 14c method, which was developed by libby, obtained by this method can be applied to the sediment. 40k/40ar proven method can be applied to glauconite, autigen feldspar, clay minerals, and sylvite are found in older sediments. isotope studies can be used to make ancient temperatures. method based on the Urey-nisbah16o/18o called benefits of temperature-can be used to estimate the temperature of formation of fossil shells in marine sediments. though "hour" and "thermometer" is still showing errors, but must be considered that they already provide a significant contribution to learning sediment.

Van't Hoff is the first to use the principle of phase to study the crystallization solutionsalt as well as the formation of salt deposits. first experimental studies on mixed crystals can produce, especially high temperature silicate system, done by some experts igneous and metamorphic petrology. most recently at the end of the decade most about this course, which attracted several experts sediment. as parable, milton & Eugster (1959) Definition wear it to examine non-marine sediments and minerals that characterize green river formation in wyoming and colorado. zen (1959) show that the principle stated by Gibbs phase which can be applied to examine the relationship of the clay minerals and carbonate minerals. zen research and then applied by Peterson (1962) in a solution of carbonate in the eastern tennessee. changes relatively new method that can be read in the works of noted Eugster (1971).

A variety of theoretical and experimental studies concerning the stability of the mineral in various oxidation-reduction conditions (Eh) and pH done by Garrels and some other experts (look Garrels & christ, 1965). research aspects of sediment geochemical much enhance our understanding about the deposition of sediment. to review books concerning topics such as the sediment geochemistry Geochemistry of sedimentskarya degens (1965) as well as the principles of chemical Sedimentology works Berner (1971).

Application or real imagery that can be seen from the geochemistry of which is the method used by sedimentologist when collecting data and evidence on the character and depositional conditions of sedimentary rocks, the chemical study of rocks, surrounding isotope geochemistry, calculated use of radiometric dating, to make sure the stone age, as well as the similarity with the source site. This method was first used in the 1970s in which the study of the sedimentology began to move toward the macroscopic and microscopic physical and chemical. with change analysis techniques and the use of electron microscopy katadoluminisen and very likely some experts sedimentology know well about the geochemical added. This rapid change to improve our relationship on diagenesa know, the pores as well as its influence on the evolution of porosity sandstones and limestones with graduation.current and evolving differences in makrosedimentologi mikrosedimentologi. makrosedimentologi ranging study of sedimentary facies to the makeup of the sediment. on the other hand, mikrosedimentologi include studies of sedimentary rocks under the microscope or better known as petrography.
