Barnett, Hydrostatic Limits in Liquids and Solids to 100 kbar, J.
A sample was pulled under 100 MPa (1 kbar), which produced clear cold-drawn section.
The core zones in feldspar ovoids showed a pressure of about 5-6 kbar and temperature of 680750 [degrees]C, while the cores of quartz megacrysts showed 4.5-6.5 kbar and 720-780 [degrees]C, respectively.
The occurrence of orthopyroxene and hercynite, and specific chemical composition of high-grade phases, such as a high Ti content in biotite and a high Al content in orthopyroxene, are in accordance with the other geothermobarometric estimates, which suggests the peak temperature of formation over 800[degrees]C and pressure of 5-6 kbar (Fig.
The idea that the accumulated elastic energy in the resin under high pressure (tens of kbar) is released under shear deformation as a new surface is not in agreement with the actual conditions in an extruder.
The present amphiboles yield pressures of 1.00-4.76 kbar, with the highest values (4.46-4.74 kbar) being derived from the amphibole poikilocrystals.
Fransolet and Schreyer (1984) concluded that the possible thermal stability field for tosudite ranges from 150[degrees]C to 350[degrees]C at 1 kbar. Maksimovic and Brindley (1980) demonstrated that the relatively high concentrations of Si and Al due to pH decrease to 4-6 are necessary for the formation of tosudite.
The rocks in the core of the dome were metamorphosed prior to the Oligocene with T-P estimates in the range of 600-700 degC and 9-14 kbar. The main focus of this report is on the Kotah dome which forms a satellite structure west of the larger Loe Sar dome.
The estimated m etamorphic conditions: T = 350-450 [degrees]C and P = 3.5-5.5 kbar, were sufficiently intense for the mobilization of the ore compounds (Grecula et al., 1996).
