Petrography, mineral chemistry, fluid inclusion microthermometry and Re–Os geochronology of the Küre volcanogenic massive sulfide deposit (Central Pontides, Northern Turkey) [PDF]

Ore Geology Reviews, 2016
The Re–Os isotopic system is applied for the first time to the sulfide ores and the overlying black-shales at the Kure volcanogenic massive sulfide deposit of the Central Pontides, Northern Turkey. The ore samples collected include predominantly pyrite, accompanied by chalcopyrite, sphalerite and other species.

Silicate-melt inclusions in recent Vesuvius lavas (A.D. 1631–1944): I. Petrography and microthermometry

European Journal of Mineralogy, 1992
Silicate-melt inclusions hosted by clinopyroxene, leucite, olivine, and plagioclase phenocrysts have been studied by petrography and microthermometry. Fourteen lavas erupted during the Mt. Vesuvius (southern Italy) recent activity (A.D. 1631-1944) have been examined.

Petrography, microthermometry, and isotopy of the gold veins from Vetas, Santander (Colombia) [PDF]

Earth Sciences Research Journal, 2020
The gold mineralization located in Vetas, Santander, consists of auriferous quartz veins hosted in Bucaramanga gneiss rocks, intrusive Jurassic rocks, and intrusive to porphyritic Miocene rocks. This study identified four mineralizing events: (1). Sericite, carbonate (ankerite and calcite?), massive and microcrystalline quartz, sphalerite, adularia ...

Ore-Forming Fluid Evolution in the Giant Gejiu Sn–Cu Polymetallic Ore Field, SW China: Evidence From Fluid Inclusions

Frontiers in Earth Science, 2021
The giant Gejiu Sn–Cu polymetallic ore deposit is one of the largest Sn producers in the world, and is related in time and space to highly evolved S type granitic intrusion. The mineralization processes can be divided into four stages: (I) skarnization; (

Hydrocarbon Accumulation Model Controlled by Overpressure Evolution in the Kelasu Thrust Belt of the Kuqa Depression, NW China

Lithosphere, 2022
The Kuqa Depression is the most representative overpressured hydrocarbon accumulation area in western China. The early rapid subsidence since 5 Ma and the strong uplift in the late period have led to a complicated evolution history of the overpressure ...
