Most primary Sn deposits worldwide are associated with muscovite-bearing peraluminous granites, commonly believed to originate from the partial melting of metasedimentary rocks. We studied whole-rock geochemistry and Sm–Nd isotopes Late Cretaceous (~90 Ma) Laojunshan granites in Youjiang Basin, South China Block. The globally significant Dulong tin mineralization was co-genetic monzogranites. e...

Background . The minerogenic specialization of the Muzkol-Rangkul anticlinorium consists in industrial gemstone deposits ruby, cordierite, almandine, aquamarine, topaz, tourmaline, scapolite, etc. Large ore objects this area are unknown. Until recently, has had a negative assessment terms rare, rare earth, and noble metals. Aim To justify identification previously unknown magnetic ring-type str...

Introduction: Knowledge of martian igneous and mantle composition is crucial for understanding mantle evolution including early differentiation, mantle convection and the chemical alteration of the surface. Primitive magmas provide critical information on their mantle source regions but most Martian meteorites crystallized from fractionated melts [1]. The new martian meteorite NWA 5789, discove...

We investigated the hydrologic, geochemical, and biogeochemical controls on stream chemical composition on the Green Lakes Valley and Andrews Creek watersheds using the alpine hydrochemical model (AHM). Both sites had comparable data sets from 1994 and 1996, including high-resolution spatial data and high-frequency time series of hydrology, geochemistry, and meteorology. The model of each water...

Previous investigations of granitoids in Sumatra were focused on age dating with minimum geochemistry composition analysis. The purpose this study is to define the classification intrusions central and explain rocks' correlation Southeast Asia tectonic activities. A polarizing microscope was used for petrography description while XRF ICP-MS applied measurements. According geochemistry, almost a...
