[1] It has come to our attention that the constitutive relationship used in the modeling of geodynamical flow problems with strongly variable physical properties, should have additional terms in the stress tensor, known in the literature as Korteweg stresses (K-stresses). These stresses arising at diffuse interfaces, which can best be explained in terms of density gradients, have already been m...

metagabbro, metadiabase and metabasalt of the chah palang and me'raji mountains associated with lower paleozoic metamorphites are situated in the south of arousan. metabasites of these areas are relatively similar in terms of mineralogy and geochemical characteristics. rock-forming minerals of the me'raji metabasites are feldspar, amphibole, biotite, sphene, epidote, chlorite ± calcite. metagab...

objective: more than 75 percent of iran is located in arid and semi-arid then land degradation and desertification are one of the crises ecological. we require a proper understanding of causes and processes of desertification to control the huge phenomenon on the global and regional situation. because southeast of iran located in arid land then assessment of desertification is very importance f...

U-Th zircon SHRIMP and U-Th-total Pb monazite CHIME ages of 6 typical samples were established among different rock types outcropped into the Chah-Dozdan batholith from Iran. The zircon population displays simple internal structures in samples of the Chah-Dozdan batholith. The zircon crystals have well-preserved magmatic characteristics. In all population, the rims display younger ages than the...

The Chah-Shaljami polymetal ore deposit contains heavy metal anomalies in various mineralization zones. Geochemical distribution and correlation of elements in surficial soilsindicate that sulfide, sulfate, sulfosalt and silicate mineral occurrences (e.g. Pyrite, chalcopyrite, galena, sphalerite, molybdenite, enargite, hornblend and biotite) in mineralization and stockwork zones resulted in the...
