Ar stepwise crushing technique has become more important for dating hydrothermal fluids trapped in mineral- hosted fluid inclusions. However, understanding the gas

Gas release systematics of mineral-hosted fluid inclusions

2019-4-15  Mineral crushing is an effective way to extract gases from fluid inclusions hosted by hydrothermal minerals (Andrawes et al., 1984, Norman and Sawkins, 1987, Norman and Musgrave, 1994, Moore et al., 2001, Camprubí et al., 2006, Blamey, 2012, Azmy and Blamey, 2013).

Prospects of the method of stepwise crushing as a source

2016-5-19  Owing to the efficient separation of gases from fluid inclusions of different generations trapped during mineral growth and/or subsequent alteration (metasomatic and hydrothermal), stepwise crushing allows us to obtain the isotopic characteristics of end-members and, thus, reliably establish the source and evolution of fluids in magmatic and postmagmatic processes; this method provides clues

Objectives: To use model mineral systems in hydrothermal experiments to develop porosity and fluid inclusions in rock-forming minerals such as silicates and carbonates. To constrain the conditions under which porosity and fluid inclusions are formed. Expected Results: These constraints (P, T, t and chemical composition) in reacting minerals will highlight potential fluid permeation within rocks.
