Chahar-Gonbad copper mine, in Kerman province, has mainly formed as veins with low reserves and medium grade. Mineralization is mainly occured as chalcopyrite, pyrite, rare galena and sphalerite. Sericitic, argillic and propylitic alterations have been identified in this are deposit. These alteration occurod in the thermal range of about 350 C. In this research, the morphology of pyrite c...

Using in situ field measurements, laboratory analyses, and numerical modeling, we test the potential efficacy of thermal stress weathering in the flaking of millimeter-thick alteration rinds observed on cobbles and boulders of Ferrar Dolerite on Mullins Glacier, McMurdo Dry Valleys (MDV). In particular, we examine whether low-magnitude stresses, arising from temperature variations over time, re...

Biphenyl is used as an intermediate for synthesis of various pharmaceutical compounds. The objective of present research was to investigate the influence of biofield treatment on physical, spectroscopic and thermal properties of biphenyl. The study was performed in two groups (control and treated). The control group remained as untreated, and biofield treatment was given to treated group. The c...
