Statistical Analysis of Sedimentology and Sedimentary Geochemistry Data of Aeolian Sediments in Khuzestan Province
The Khuzestan plain is located in south western of Iran and is covered about 3.9 percent of the country area. Khuzestan plain is mostly covered by the Quaternary deposits. The thickness of these deposits exceeds 300m in some areas .Sedimentology and geochemistry of sand dunes producing centers are not only important for determining sedimentary and geochemical features of the particles possible ...

ویژگی های زمین شیمیایی، کانی شناسی، و میکرومورفولوژیکی خاک ها و سنگ مادر مربوطه در منطقه بین بخش های جنوبی زاگرس و خلیج فارس تا دریای عمان(استان هرمزگان، ایران) مورد بررسی قرار گرفت. هدف های این مطالعه شناسایی تغییرات در خصوصیات فیزیکی، شیمیایی، و ترکیب کانی شناسی خاک، مطالعه میکرومورفولوژی و تکامل خاک، و بررسی توزیع عنصر خاک بر اساس هوازدگی، پروسه های خاک و زمین شناسی جهت توصیف اثرات مواد مادر...
15 صفحه اولData interpretation in forensic sediment and soil geochemistry
Automated geochemical techniques enable reproducible elemental assays of small quantity samples and have been used in recent years in many forensic criminal investigations in England and Wales. Two case studies are presented which highlight the problems of testing the presence of pre-, synor post-crime event sample mixing. The number of elements or compounds analysed can have a bearing upon sta...
متن کاملIsotope Geochemistry
Isotopic analysis can be performed on minerals, rocks, soil, tissue, gases, and liquids – just about anything. In view of the broad possibilities, we will only cover a few generalities here. In most instances, the element to be analyzed must be first isolated and purified before it can undergo isotopic analysis in a mass spectrometer. Purification is necessary to avoid isobaric interferences an...
متن کاملThe genetics of geochemistry.
Bacteria are remarkable in their metabolic diversity due to their ability to harvest energy from myriad oxidation and reduction reactions. In some cases, their metabolisms involve redox transformations of metal(loid)s, which lead to the precipitation, transformation, or dissolution of minerals. Microorganism/mineral interactions not only affect the geochemistry of modern environments, but may a...
