Fluid inclusions in quartz: Implications for hydrocarbon ...

Furthermore fluid inclusions in quartz are seen at distinct stratigraphic reservoir levels. These inclusions occur in Oligocene reservoirs in Groups L and M and in Miocene reservoirs of Groups K and H. However to-date no oil inclusions have been found in Groups I and J. There appear to be two distinct populations of fluid inclusions in the

vent chemistry data (e.g. [10]). Fluid inclusion assem-blages in quartz from active and recent VMS-forming sub-marine hydrothermal systems sometimes contain coexist-ing liquid-rich and vapor-rich inclusions indicating that the host quartz was precipitated from immiscible fluids ( [8] and references therein). Halite-bearing inclusions

These findings support the proposal that deformed fluid inclusions can serve as monitors of both the orientation and magnitude of deviatoric stresses during low-strain ductile deformation of quartz-bearing rocks.

Water- and Boron-Rich Melt Inclusions in Quartz from the ...

As well as both melt inclusion types there are syngenetic fluid inclusions which visually are often the dominant type. In quartz from the miarolitic cavities the quantity of fluid inclusions conspicuously increases from the root zone into the main body of the crystals. Most of these fluid inclusions contain sassolite daughter crystals.

Quartz precipitation and fluid inclusion characteristics in ...

Results of a numerical modeling study of quartz dissolution and precipitation in a sub-seafloor hydrothermal system have been used to predict where in the system quartz could be deposited and potentially trap fluid inclusions. The spatial distribution of zones of quartz dissolution and precipitation is complex owing to the fact that quartz solubility depends on many inter-related factors ...

In addition many factors including the thickness of quartz slice size and location of fluid inclusions decrease the analytical accuracy of EMP on fluid inclusions to qualitative and semi-quantitative levels. For instance the fluid inclusions regularly distributed on the surface of quartz slices cannot be analyzed by EMP.

Water- and Boron-Rich Melt Inclusions in Quartz from the ...

By normal alteration process the primary gel or sol phases are transformed into a fluid inclusion with large amounts of solids—mostly quartz and cristobalite which cannot be homogenized at the trapping conditions (Thomas and Davidson [ 9 ]). 2.

The results of the two studies converge indicating that density changes in neonate inclusions are promoted by high differential stresses long periods at high P and high T and fluid compositions that maximize quartz solubility.
