We investigated the crystal and structural behavior of Cr-bearing spinels from Archean chromitites Sittampundi (India), which had been subjected to very high-grade metamorphism. The data show that their oxygen positional parameters are among highest ever recorded for with similar Cr# Mg# those found other occurrences. general agreement between electron microprobe Mössbauer indicates analyzed st...

Dense deposit disease (DDD) is an orphan disease that primarily affects children and young adults without sexual predilection. Studies of its pathophysiology have shown conclusively that it is caused by fluid-phase dysregulation of the alternative pathway of complement, however the role played by genetics and autoantibodies like C3 nephritic factors must be more thoroughly defined if we are to ...

barika gold (and silver) rich massive sulfide deposit is located 18 km east of sardasht, north western part of sanandaj-sirjan metamorphic zone. rock units outcropped in this area are cretaceous metamorphosed volcano-sedimentary rocks in green schist facies, and include association of meta-andesite, meta-tuffite, phyllite and slate rocks, where the meta-andesitic unit (kmv1) is host rock to the...

Yeylagh-e-Gharechi porphyry copper deposit is located in the Arasbaran metallogenic belt at northwestern Iran, 25 kilometer of Ahar. Porphyry mineralization at the Yeylagh-e-Gharechi deposit occurred in post-Oligocene quartz monzonite and monzonite bodies which was hosted by Eocene volcanic rocks. Mineralization occurred as veins, veinlets and dissemination in hypogene zone. Supergene zone has ...
