The Shand Cu-Mo deposit is located in the Orkhon-Selenge depression, Northern Mongolia. It lies near Erdenetiin Ovoo porphyry deposit, which together define one of Mongolian’s most economically significant metallogenic belts. In (Au?) several ore related breccia types are associated with porphyritic granodiorite intrusions, and they contain pre-, synand post-mineralized stocks, magmatic-hydroth...

Abstract The Pliensbachian–Toarcian transition was characterised by a drastic turnover from cool climate to period of rapid global warming. While the warming associated with Early Toarcian Oceanic Anoxic Event is rather well-studied, cause, intensity and extent preceding cooling in late Pliensbachian are still discussed. Occurrences glendonite play an important role this debate, since pseudomor...

The Xinchenggou area is located in the northeast part of eastern segment Xingmeng orogenic belt (EXOB), NE China and has been demonstrated to be a promising exploration target for epithermal deposits. Although previous studies have shown that syenogranite monzogranite occurring are forming mineralization, petrogenesis geodynamic settings which these granites were emplaced still unclear. To addr...

The basement of eastern Mexico comprises Grenvillian-age granulite-facies metamorphic rocks. Oaxacan Complex represents the largest outcrop belt this in Mexico. In work, southwestern garnets are studied from a petrographical, geochemical, and geothermobarometrical perspective for first time. display different grain sizes nucleated polyphase evolution. almandine end member proportion is similar ...

Abstract The Piedemonte Llanero Basin is located on the eastern side of Eastern Cordillera Colombian Andes. It has been subject numerous geological studies carried out for oil sector, mainly. This study presents coal-petrographical features 15 coal seams four formations from Late Cretaceous to Middle Miocene (Chipaque formation, Palmichal group, Arcillas del Limbo and San Fernando formation). A...

A sedimentological, biostratigraphic, and petrographical investigation was conducted on exposed sedimentary rocks in the Seulimeum Formation Northwest Aceh Basin, Sumatra. Sedimentary facies analysis suggests a deep-marine depositional environment consists of an inner fan, middle outer fan to basin plain deposits. New foraminiferal data designated late Miocene early Pleistocene age for studied ...
