Development of computational modeling tools has revolutionized studies magmatic processes over the last four decades. Their refinement from binary mixing equations to thermodynamically controlled geochemical assimilation models provided more comprehensive and detailed constraints an array systems. One questions that not yet been vigorously studied using thermodynamic is origin massif-type anort...

The Sanak-Baranof plutonic belt (SBPB) includes a series of biotite tonalite, granodiorite, and granite neartrench plutons that intrude the Campanian to Eocene flysch of the Chugach-Prince William terrane (CPW) for 2100 km along the southern Alaskan margin (Hudson et al., 1979; Hill et al., 1981; Bradley et al., 2003; Haeussler et al., 2003). SBPB intrusions have been interpreted to be the resu...

I Circa 1.1 Ga granitic magmatism in Texas was manifested as two compositional groups: (1) the 1.12 Ga Red Bluff granitic suite in west Texas; and (2) 1.12-1.07 Ga granites of the Llano uplift of central Texas. Both suites share some characteristics typical of 'anorogenic' granites (e.g. potassiumand iron-rich bulk compositions, Fe-rich hydrous silicates, emplacement conditions involving low ox...

The Wadi Dib magmatic complex is the oldest known alkaline ring complex in the Egyptian part of the Pan-African orogenic belt. Rb-Sr isotope data for seven samples suggest a Vendian age of 578=k16 Ma, and a 87Sr/S6Sr initial ratio of 0.7048±0.0010. The igneous complex has a diameter of 2 km and was emplaced within granodioritic Pan-African host rocks at the intersection of two faults. It shows ...

Introduction: Martian (SNC) meteorites are igneous rocks that range from a reduced, trace-element depleted end member to an oxidized, trace-element enriched end member [1-3] (Figure 1). One interpretation of this trend is that relatively reduced, depleted magmas are partial melts of a reduced peridotitic mantle, whereas more oxidized, enriched magmas are mantle-derived magmas contaminated by ox...

A lot of troilite reaction rim textures formed through sulfidation of FeNi alloy of kamacite and taenite with sulfur rich gas have been identified especially in C03 unequilibrated carbonaceous chondrites. Troilite formation through sulfidation of FeNi alloy of kamacite and taenite with sulfur rich gas in the solar nebula is expected from the reaction kinetics as well as from the equilibrium con...
