Khut skarn deposit, located in the 50 Km NW of Taft,has formedin the result of Khut granodiorite intrusion into the upper Triassic impure carbonate rocks.Field evidences and mineralogical studies show Khut skarn is calcic type and exoskarn is the major skarn zone in area which associated with ore mineralization.The microprobe analyses show that there are two major types of garnet at garnet-pyro...
The Oshvand Skarn deposit is located about 10 km east of Nahavand city in the Sanandaj-Sirjan structural zone. In this area, garnet (grossular-andradite) is the most abundant mineral in the skarn zone and their compositions are in the range of Adr(67.2 - 45.9%) Gro(50.1 - 31.8%) Sps(1.8 - 0.3%) and Prp(2.5 - 0.6%). EPMA data indicate a decrease in andradite and increase in the amounts of grossu...
A total of 73 peridotitic mantle xenoliths and a set of garnet and clinopyroxene xenocrysts from the recently discovered Jurassic Monk Hill kimberlite (UCO-H77A) in South Australia were used to constrain the thermal and compositional structure of the lithospheric mantle beneath the Adelaide Fold Belt, which is located at the southeastern margin of the Australian craton. The xenoliths contain mo...
Organic light-emitting diodes (OLEDs) with a Ba-doped tris(8-quinolinolato)aluminum(III) (Alq3) layer were fabricated to reduce the barrier height for electron injection and to improve the electron conductivity. In the OLED consisting of glass/ITO/4,4',4"-tris[2-naphthylphenyl-1-phenylamino]triphenylamine (2-TNATA, 30 nm)/4,4'-bis[N-(1-napthyl)-N-phenyl-amino]-biphenyl (NPB, 18 nm)/Alq3 (42 nm)...
introduction: ablative and nonablative lasers have been used to treat melasma. we aimed to assess and compare the combining q-switched nd:yag laser (qsnyl) and fractional erbium:yag laser (feyl) with qsnyl alone in treatment of melasma. methods: this randomized controlled clinical trial was performed in our research center during 2013-2014. women with melasma and without a history of keloid for...

We explore Fe/Mn and Nb/Ta ratios of basalts as potential tracers for differentiating melts of recycled mafic crustal lithologies from peridotitic melts. Trace elements and Fe/Mn ratios of the Mesozoic and Cenozoic basalts from East China were analyzed by ICP-MS. Low Nb/Ta ratios (15.4 ± 0.3 (2r, n = 45)), high Nb and Ta contents (60.1 and 4.01 ppm) and high Fe/ Mn ratios (64.7 ± 1.5 (2r, n = 4...
In this work, Fe3+ substituted bismuth yttrium iron garnet particles Bi0.5Y2.5-xFe5+xO12 (x=0.0, 0.1, 0.2) were synthesized by the sol-gel method. X-ray diffraction (XRD) patterns confirmed the pure garnet structure for 0.0 and 0.1 samples and formation of YIP and phases in x = 0.2 sample. The results of vibrating sample magnetometer (VSM) measurements represent that saturation magnetization i...
