The Hongniu-Hongshan porphyry-skarn deposit is located in the southern Yidun terrane Sanjiang Tethyan Metallogenic Domain (STMD). Although its metallogenesis has been well constrained past decade, magmatic processes for granitoids are still poorly understood. Herein, we provide new geochemical data on minerals (plagioclase, amphibole, and clinopyroxene) to get a better insight into these proces...

Aghadjari bauxite deposit is located in ~15km south of Shahindezh, West-Azarbaidjan province. This deposit was developed as stratiform lenses along the contact of Rutheh and Elika carbonate formations. Bauxitization processes led to the formation of boehmite, diaspore, kaolinite, pyrophyllite, illite, hematite, goethite, anatase, rutile, and quartz. Ferrugenization and deferrugenization mechani...

Taking advantage of a multi-sensor (multispectral and magnetic) drone survey, we address the detailed geological mapping modeling mineralization in its environment. We stress that these high-resolution data allow us to bridge gap between field observations regional aeromagnetic survey. On one hand, combination multispectral imagery with enhances mapping. other magnetic susceptibility measuremen...
