Mineralogy and geochemistry of major, trace and REE elements, Pirashkaft Bauxite Deposits, Mamasani, Fars Province
The Pirashkaft bauxite deposit is located in north of the Paskuhak anticline in the Fars Province. The bauxite deposit present between Sarvak and Gurpy Formations, and formed during the Late Turonian time as a consequent of the Laramid orogeny phase. According to the geological investigations, the Pirashkaft bauxite is Karstic type. The residual ore studied in the Pirashkaft can be classified ...

متن کاملP-126: Assessment of Some Trace Elements and Other Criteria of Infertile Patients
Background: The aim of present study was to estimate the levels of some Trace element (Lead, Copper, Cobalt, Chromium, and Cademium) concentrations in Asthenospermia and Normospermia by atomic absorption method, in comparison with control (Fertile), Estimate concentration of (MDA) Malondialdehyde and Total protein concentration in semen specimens.Also relationships between mentioned components ...
متن کاملBiological interaction of selenium with other trace elements in chicks.
Studies were conducted to determine whether or not elements whose valence shell of electrons was similar to that of selenium would reverse the toxicity of selenium to chicks. The elements studied were arsenic, tellurium, tin, and lead. Each of these elements, when added to the diet of chicks, reversed the toxicity of 25 ppm selenium as measured by weight gain. In spite of the protection afforde...
متن کاملEnamel diagenesis at South African Australopith sites: Implications for paleoecological reconstruction with trace elements
Elemental ratio data from archaeological and paleontological bone have often been used for paleoecological reconstruction, but recent studies have shown that, even when solubility profiling techniques are employed in an attempt to recover biogenic signals, bone is an unreliable material. As a result, there has been renewed interest in using enamel for such studies, as it is known to be less sus...
