abstract the influence of cation?? and anion?? interactions on the strength and nature of n…h hydrogen bond has been investigated by quantum chemical calculations in s-triazine…3hf complex. ab initio calculations were performed at mp2/6-311++g(d,p) level of theory. the natural bond orbital (nbo) analysis and the bader’s quantum theory of atoms in molecules (aim) were also used to elucidate t...
baft ophiolite mélange is a part of naein-baft ophiolite (southeast of kerman province in iran). serpentinites from baft ophiolite mélange contain different types of spinels such as chromite, chromespinel, ferritchromite and magnetite which can reveal different stages of evolution in host serpentinites. the compositions of baft chromites show that they belong to podiform chromitites that may ha...
aminocarboxylic acids, such as 2-aminobenzoic acid, react easily with [ir(cod)(pme3)3]cl, (cod=1,5-cyclooctadiene), in thf to produce hydridoaminocarboxylato iridium(iii) complexes in high yields. these octahedral complexes are formed via oxidative addition reaction of the o-h bond of the carboxylic group with the central metal. the starting iridium(i) complex losses the cod molecule, the chlor...
The Bayazeh ophiolite, with probable Paleozoic age, is cropped out along the Bayazeh fault and located in the eastern margin of the Yazd block (Central Iran). In the field, this ophiolite consists of serpentinized peridotites, metagabbro, ultrabasic metamorphosed dikes, metapicrite, serpentinite and metalistvenite. Development of serpentinization process in the Bayazeh mantle peridotites has be...
Mafic–ultramafics complexes are crucial for their tectonic implication, upper mantle condition, and hosting industrial minerals in a region. This study aims to highlight characterize the mafic–ultramafic rocks of Logar Ophiolite Complex using integration geospatial technology field data. The spatial distribution ophiolitic complex was examined this mineralogical indices (MI), band ratio (BR), s...
Samsour ophiolite is located in Sistan and Baluchestan Province, about 210 Km southwest of Zahedan city. Based on structural and sedimentary classification of Iran, this ophiolite is located adjacent to NosratAbad-Karvandar fault and belongs to Sistan suture zone. Rock units of this ophiolite are mainly composed of ultramafic, including gabbro (Layerd and massive) and doleriteic. In the micros...
