Abstract The thick mantle lithosphere beneath cratons consists of strongly reduced rocks that have reacted with oxidized melts. These low-silica, incipient melts are rich in CO 2 and H O react surrounding forming an enriched zone at the base lithosphere, which is source region for many diamonds. Here, we reproduce these reactions novel experiments oxidised, hydrous carbonate-rich reduced, deple...
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
Spid pluton with Neogene age outcrop in the Urumieh-Dokhtar Magmatic belt. Amphibole in this intrusion is calcic and magmatic and its composition corresponds to magnesiohornblende to actinolite which reflects the type I granitoid. Geobarometry calculations show that the amphibole crystalized at pressure of 2.5 to 3.7 kbr corresponding to a depth of 8 to 12 km. Based on geothermometry of hornble...
The objective of this study was to investigate the clay mineralogy of soils derived from different parent materials in Binaloud zone, western Mashhad. Two soil profiles on the summit of granitic, ultrabasic and metamorphic rocks were described and sampled from genetic horizons. Clay fraction of the soils was analyzed using X-ray diffraction method. Chlorite, smectite, mica, amphibole and regula...
