Daniel M. Unruh, Karen Lund, Mel A. Kuntz, Lawrence W. Snee
2008, Open-File Report 2008-1142
Across the Salmon River suture in western Idaho, where allochthonous Permian to Cretaceous oceanic rocks are juxtaposed against Proterozoic North American rocks, a wide variety of plutonic rocks are exposed. Available data indicate much variation in composition, source, and structural state of these plutons. The plutonic rocks were long described...

Experimental investigation on thermochemical sulfate reduction by H2S initiation
Tongwei Zhang, Alon Amrani, Geoffrey S Ellis, Qisheng Ma, Yongchun Tang, David Applegate
2008, Geochimica et Cosmochimica Acta (72) 3518-3530
Hydrogen sulfide (H2S) is known to catalyze thermochemical sulfate reduction (TSR) by hydrocarbons (HC), but the reaction mechanism remains unclear. To understand the mechanism of this catalytic reaction, a series of isothermal gold-tube hydrous pyrolysis experiments were conducted at 330 °C for 24 h under a constant confining pressure of 24.1 MPa. The...

Qisheng Ma, Geoffrey S Ellis, Alon Amrani, Tongwei Zhang, Yongchun Tang
2008, Geochimica et Cosmochimica Acta (72) 4565-4576
The abiotic, thermochemically controlled reduction of sulfate to hydrogen sulfide coupled with the oxidation of hydrocarbons, is termed thermochemical sulfate reduction (TSR), and is an important alteration process that affects petroleum accumulations in nature. Although TSR is commonly observed in high-temperature carbonate reservoirs, it has proven difficult to simulate in...
Estimation of the change in freshwater volume in the North Coast Limestone upper aquifer of Puerto Rico in the Rio Grande de Manati-Rio de la Plata area between 1960 and 1990 and Implications on public-supply water availability
