Diagenesis of the Vaca Muerta Formation, Neuquén Basin: Evidence from petrography, microthermometry and geochemistry

Marine and Petroleum Geology, 2021
Abstract The Tithonian Vaca Muerta Formation (500 m-thick marine carbonates) in the Pampa de Tril area is a potential unconventional hydrocarbon reservoir but earlier studies rarely focused on its diagenetic history. It constitutes the upper part of the lower Mendoza Group in the Neuquen Basin, western Argentina. Petrographic examinations reveal four

PETROGRAPHY, CHEMISTRY, AND NEAR-INFRARED MICROTHERMOMETRY OF INDIUM-BEARING SPHALERITE FROM THE TOYOHA POLYMETALLIC DEPOSIT, JAPAN

Economic Geology, 2012
Textural, chemical, and microthermometric characteristics of In-bearing sphalerite from the Toyoha Zn-Pb-Ag-Cu-Sn-In vein-type deposit are investigated using petrography, X-ray mapping, electron microprobe analyses, and near-infrared (NIR) microscopy. The studied ore is rich in zinc and mainly consists of sphalerite.

Fluid Inclusion Petrography and Microthermometry of Barren/Mineralized Quartz Veins-Reef of Malanjkhand Cu Deposit, Central India: Implication on Ore and Non-Ore Forming Environment

Journal of Geosciences Research
Quartz reefs and veins of variable thickness have been intruded in host Paleoproterozoic Malanjkhand granites in the mine area and are primarily restricted to phyllic as well as potassic alteration zones. They are mainly of two types: mineralized and barren.

Petrography and Microthermometry of Fluid Inclusions in Apatite in the Turamdih Uranium Deposit, Singhbhum Shear Zone, Eastern India - An Insight into Ore Forming Fluid

Journal of the Geological Society of India, 2015
AbstractThe Singbhum shear zone is one of most important polymetallic mineralized zone, characterized by uranium, Cu and apatite-magnetite mineralization. Although there is unanimity regarding the hydrothermal nature of different ores, the fluid characters, particularly related to apatite-magnetite mineralization, are not very well-c onstrained.
