A comprehensive geological, geochemical, and petrogenetic study of hotspot-related oceanic basalt-rhyolite series rocks from Ascension Island, South Atlantic Ocean.
(1997)
The mafic rocks (basalt-hawaiite-mugearite-benmoreite) of Ascension Island form four distinct groups: low Zr/Nb hawaiite, high Zr/Nb basalt, intermediate Zr/Nb basalt to benmoreite, and Dark Slope Crater (DSC) hawaiite and ...
Petrology of the Mount Scott Granite.
(1998)
The Mount Scott Granite intruded into the Carlton Rhyolite Group as part of a package of contiguous, consanguineous, and coeval (CCC) granites. Modeling of compositional data suggests the Mount Scott Granite shared a ...
Petroleum wax deposition and production geochemistry: Experimental results and field examples.
(1999)
The present study targets several main aspects of the problem of petroleum wax deposition. The first aspect to be examined is the change in solubility of n-alkane mixtures and wax deposits as related to variability in their ...
Chemical remagnetization caused by burial diagenesis: Testing the hypothesis in the Pennsylvanian Belden Formation, Colorado.
(1997)
The TVRM present in Belden carbonates is pervasive whereas the CRM is widespread but site specific, thus providing an opportunity to magnetically characterize the two components. Specimens with the CRM have higher saturation ...
Geochemical characterization of solid bitumen deposited within the Mississippian sandstone reservoir of the Hitch Field, southwest Kansas.
(2006)
The occurrence of solid bitumen in petroleum reservoirs is a common phenomenon in many petroliferous basins worldwide. Solid bitumen was recently identified within the Upper Mississippian (Chesterian) sandstone reservoir ...
Widespread chemical remagnetization: Orogenic fluids or burial diagenesis of clays?
(1998)
The results of this study indicate that widespread or pervasive chemical remanent magnetizations (CRMs) can form as a consequence of the burial diagenetic conversion of smectite to illite. Paleomagnetic, rock magnetic, and ...
Calcite-water reaction rates at reservoir conditions.
(2002)
A numerical model was developed for predicting calcite scale precipitation in near-wellbore regions during water flooding and petroleum recovery operations. Rate equations based on the experimental studies were used to ...
Source rock geochemistry and liquid and solid petroleum occurrences of the Ouachita Mountains, Oklahoma.
(1981)
Several stratigraphic intervals in the Ouachita Mountains possess adequate source potential for petroleum generation, based on contents of total organic carbon and extractable organic matter. Mississippian/Devonian rocks ...
Geochemical characterization of organic matter in Victoria Harbour sediments, Hong Kong.
(2006)
The organic carbon-to-nitrogen ratio demonstrated fluctuations in the sources of organic matter throughout the Holocene unit of MBH 54/2. High fluxes in the carbon-to-nitrogen ratio may reflect strong storms, where excess ...
