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.

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 ...
