Fluid-inclusion studies of regionally extensive epigenetic dolomites, Bonneterre Dolomite (Cambrian), southeast Missouri: evidence of multiple fluids during dolomitization and lead-zinc mineralization
Article Abstract:
The conclusions reached by Shelton et al on the thermal regime, sources of fluids and mineralization type of the regionally extensive epigenetic dolomites of southeast Missouri is criticised. Shelton et al did not consider the necking of fluid inclusion. In reply, the original conclusions are retained and the contention of a regional thermal gradient in the Ozark Region Mississippi Valley-Type deposits, based from fluid-inclusion evidence, is negated. A pulsing basinal brine is used to explain the temperature and composition of the inclusion.

High temperature stability limit of phase egg, AlSiO(sub 3)(OH)
Article Abstract:
Using a high pressure apparatus, researchers investigate the effects of high temperature on the stability of a phase egg. Topics include how high temperatures increase Al(2)O(3) content in stishovite, and the ability of phase egg and topaz-OH to transport water to the earth mantle's transition zone.
