Analyses of the fluid inclusions show that oxygen levels were very high during this time; this would support evidence for intense combustion.
12.
These fluid inclusions provide direct information about the composition of the fluid and the pressure-temperature conditions that existed during diagenesis of the sediments.
13.
In the recent years, fluid inclusion research has been extensively applied to understand the role of fluids in the deep crust and crust-mantle interface.
14.
Fluid inclusions are microscopic bubbles of aqueous solutions which were trapped within crystals during crystallization and are considered as relic samples of the mineralizing waters.
15.
CO 2-rich fluid inclusions were also recorded from a number of ultrahigh-temperature granulite facies terranes suggesting the involvement of CO 2 in extreme crustal metamorphism.
16.
Microbial studies on fluid inclusions are foreseen to attempt to evidence the presence of ancient micro-organisms in the original fluid solution in which the crystals developed.
17.
Nahcolite was first described in 1928 for an occurrence in a differentiated alkalic massifs; in fluid inclusions as a daughter mineral phase and in evaporite deposits.
18.
Melt inclusions and fluid inclusions can provide physical and chemical information of the geological environment in which the melt or fluid are trapped within the crystal.
19.
Analyses of fluid inclusions in ancient amber suggest that the oxygen content of the atmosphere was very high ( 30 35 % ) during the late Cretaceous.
20.
The sequence is worked out through detailed microscopic studies in polished ore mineral section, petrologic thin section and fluid inclusion studies as well as macroscopic field relations.
