The Vathi porphyry Cu-Au ± Mo mineralization is located in the Serbo-Macedonian metallogenic province of Western Tethyan Metallogenic Belt. It mainly hosted by a latite and genetically associated with quartz monzonite intrusion, which intruded basement rocks Vertiskos Unit latite, 18 to 17 Ma ago. A phreatic breccia crosscuts latite. was affected potassic alteration, whereas subjected local pro...

The occurrences of silica deposits (quartz veins, silica sinters, silica scales) suggest that precipitation via nucleation and overgrowth on pre-existing mineral surfaces occurs under crustal conditions. We conducted hydrothermal flow-through experiments on silica precipitation using no mineral substrate at 120–430 °C and 31 MPa for understanding the effects of the aluminum on the mineralogy an...

The Tareek Darreh gold deposit is located 40km north of Torbat-e Jaam in the Khorassan-Razavi province, NE-Iran. The study area mainly comprises slightly metamorphosed, sedimentary rocks of Jurassic age including alternation of shale, siltstone, and sandstone. These rocks have been intruded by plutonic rocks such as gabbro-norite, diorite, quartz-diorite, and rhyodacite. The ore bodes are expos...

It is recognized that magmatic activities have occurred along the Izmir Erzincan suture due to closure of Tethyan ocean. In western part Almus (Tokat), which situated around this zone, quartz veins fracture lines are observed in volcanics owing magmatism. There copper enrichments with an average thickness 70 cm volcanic rocks. Mineralization as vein type and epigenetic formation. Paragenesis co...

Fluorites are found in the region between Hamit, Karakütük, Bayındır and Yeniyapan villages of Kaman District (Kırşehir-Türkiye). located altered levels due to faults quartz syenites containing gray-pink colored K-feldspar, plagioclase quartz, amphibole biotite type mafic minerals Upper Cretaceous aged. Central Anatolian Granitoids, observed purple green places, pink, yellow, white colors as ve...

Introduction: Shock-metamorphic effects including shatter cones, planar deformation features (PDFs) in quartz grains, and both E-and S-type pseu-dotachylites were discovered in deeply eroded Ar-chean granites near the Yarrabubba homestead in Western Australia (119°50'E, 27°10'S). Preliminary estimates indicate that the Yarrabubba impact structure is of a Paleoproterozoic age and at least 30 km ...
