Porphyry deposits are the dominant sources of copper and major several base precious metals. They commonly formed via repeated emplacement hydrous magmas associated fluid exsolution. As a result, mineralized hydrothermal veins may undergo multiple deposition reopening processes that not fully accounted for by existing models. The Tongchang porphyry Cu deposit is rare example being related to si...

Abstract. Raman elastic thermobarometry has recently been applied in many petrological studies to recover the pressure and temperature (P–T) conditions of mineral inclusion entrapment. Existing modelling methods petrology either adopt an assumption a spherical, isotropic embedded isotropic, infinite host or use numerical techniques such as finite-element method simulate residual stress strain s...

The Los Cabos Block, at the southern end of Baja California, exposes part Late Cretaceous Peninsular Ranges Batholith over 2700 km2. In block, Batholitic Complex is exposed in two massifs, Sierra La Laguna to west and Trinidad east. sierras are separated by ~75 km long, N-S striking, San José del Cabo extensional fault system, homonymous basin. Here, we present field observations, new U–Pb Ar–A...

Strongly SiO2-undersaturated alkalic rocks (Mg# > 50, SiO2 ≤ 45 wt%, Na2O + K2O ≥ 3 wt%) occur in three early-stage (Sarnu-Dandali, Mundwara, Bhuj) and one late-stage (Murud-Janjira) rift-associated volcanic complexes the Cretaceous-Paleogene Deccan Traps flood basalt province of India. Thermobarometry based on clinopyroxene-liquid equilibrium suggests that they mostly crystallized beneath Moho...

The Eocene-Oligocene Sarbisheh volcanic complex is a part of the Lut-Sistan Zone that outcrops in eastern Iran. In the east of this complex, three groups of volcanic rocks (i.e., andesite, dacite, and rhyolite) exist. Plagioclase as the main mineral of these rocks is found with varying micro-textures. Based on a changing trend in the concentration of anorthite, the developed micro-textures (coa...
