The Accumulation Characteristics of the Paleozoic Reservoir in the Central-Southern Ordos Basin Recorded by Organic Inclusions

open access: yesGeofluids, 2021
The Permian tight clastic reservoir and Ordovician carbonate reservoir were developed in the central-southern Ordos Basin. This study investigated the fluid inclusion petrography, diagenetic fluid characteristics, formation process of natural gas ...

Cap rock efficiency of geothermal systems in fold-and-thrust belts: Evidence from paleo-thermal and structural analyses in Rosario de La Frontera geothermal area (NW Argentina) [PDF]

open access: yes, 2016
Cap rock characterization of geothermal systems is often neglected despite fracturing may reduce its efficiency and favours fluid migration. We investigated the siliciclastic cap rock of Rosario de La Frontera geothermal system (NW Argentina) in order to

Determination of total contents of fluid inclusions in quartz using modal analysis: Examples from Proterozoic rocks and ore deposits in Finland [PDF]

open access: yesBulletin of the Geological Society of Finland, 1989
A modified linear measurement procedure following Rosiwal's method to determine the total volume contents of fluid inclusions in minerals is described. The contents were determined from quartz crystals and grains in 13 Proterozoic rock and ore specimens ...

Fluid inclusion petrography

open access: yesLithos, 2001
Abstract A procedure of fluid inclusion studies is proposed with emphasis on the criteria of selecting fluid inclusions for detailed (microthermometry and spectroscopic) analysis. An overview of descriptive and genetic classifications of fluid inclusions in single crystals and in massive rocks is given with the intention of further differentiating ...

UV-fs-LA-ICP-MS Analysis of CO2-Rich Fluid Inclusions in a Frozen State: Example from the Dahu Au-Mo Deposit, Xiaoqinling Region, Central China

open access: yesGeofluids, 2018
The recently developed technique of ultraviolet femtosecond laser ablation inductively coupled plasma mass spectrometry (UV-fs-LA-ICP-MS) combined with a freezing cell is expected to improve the analysis of CO2-rich fluid inclusions by decreasing their ...

Determination of Solid-Liquid Phase Composition of Fluid Inclusions in Minerals by SEM-EDS Coupled with Cryotransfer

open access: yesYankuang ceshi, 2015
Daughter mineral species, chemical compositions and distribution of daughter minerals in fluid inclusions can provide important constraints on the composition of hydrothermal fluids, physicochemical conditions of mineralization, the regularity of fluid ...

Amphibole: A major carrier of helium isotopes in crustal rocks [PDF]

open access: yes, 2016
The first evidence for a specific role of amphiboles in He isotope balance of crustal rocks was presented in early contributions by Gerling et al. (1971, 1976).
