American Mineralogist (1949) 34 (5-6): 413–421.
...P. A. Peach Abstract In the past the use of fluid inclusions in minerals as a geothermometer has been confined to the direct observation of the disappearance of the gas phase by means of a microscope and heating stage. More recently the breaking out of the inclusions as the mineral is heated, has...

... decrepitate upon heating before total homogenization, which could suggest that they also trapped excess carbonic vapor. They show petrographic and microthermometric evidence for postentrapment reequilibration, prohibiting their use as accurate geothermometers and geobarometers. Previous studies on chlorite...

..., or pyrrhotite next to fragments of altered country rocks, or disseminated in the alteration haloes. Arsenic in arsenopyrite and Al iv in chlorite geothermometers indicate that wall-rock alteration and ore mineral precipitation occurred at temperatures between 400° and 250°C. Fluid inclusions in vein quartz...

...Chenhui Fei; Jingbo Liu Abstract Vaterite was identified in a decrepitated carbonaceous material (CM) bearing inclusion in zircon from a stromatic migmatite in the Chinese Sulu ultrahigh-pressure (UHP) metamorphic terrane. It is associated with nanometer to micrometer anhedral diamonds, aragonite...

.... These apparently empty inclusions, as well as inclusions still containing some CO 2 , often show microcracks (some tens of μm long) emanating from the tip of negative-crystal shaped inclusions ( Fig. 2b ). Other large empty inclusions show typical decrepitation textures with irregular inclusion shapes ( Fig. 2c...

.... The needles ultimately decrepitated during retrogression. We note that micaceous needle-shaped multiphase inclusions are rarely described; the closest analogs of which we are aware are found in UHP garnets of the Erzgebirge ( Perchuk 2008 ). The Brimfield Schist in this area underwent ultrahigh-temperature...
