The porosity and permeability of sandstone and carbonate reservoirs (known as reservoir
quality) are essential inputs for successful oil and gas resource exploration and exploitation …

Petroleum-bearing fluid inclusions are small encapsulations of oil and gas that offer an
invaluable opportunity to better constrain the evolution of petroleum systems. Insights into …

A fundamental question in the study of magmatic-hydrothermal ore deposits is whether the
mineralization potential of intrusions was already predetermined by the metal content of the …

Stable carbon and oxygen isotopes (δ18O and δ13C values) and trace elements have been
applied to the study of diagenesis of carbonate rocks for over 50 years. As valuable as these …

Aqueous fluids containing various amounts of salts are common in many geologic
environments. In most environments, NaCl, KCl or CaCl 2 is the dominant salt, but MgCl 2 or …

Abstract The porphyry Cu-Mo deposit in Butte, Montana, formed where magmatic

Abstract Deep core (> 4.9 km) from Ediacaran Deng IV Member algal dolomites in the
Gaoshiti-Moxi block in the Sichuan Basin, southwest China, reveals multiple generations of …

A giant fault-controlled oilfield has been found in the ultra-deep (greater than 6000 m)
Ordovician carbonate strata in the northern Tarim Basin. It is of great significance for …

Quartz-hosted brine inclusions that homogenize via halite dissolution occur in many
magmatic-hydrothermal systems. In many cases their calculated minimum entrapment …

Abstract The El Callao mining district is the most important gold-producing region in
Venezuela. It is hosted in the Paleoproterozoic Guasipati-El Callao greenstone belt, which …
