The Wadi Bidah Mineral District located in the Neoproterozoic (900–550 Ma) Arabian Shield of southwestern Saudi Arabia contains small, well-exposed, stratabound, volcanogenic massive sulfide deposits and associated zones of hydrothermal alteration. This dissertation combines new…

In this project, two aspects of the action of hydrogen sulfide and reactive sulfur species have been studied: cytotoxic and cytoprotective effects. Freshly isolated hepatocytes have been used in order to examine the prevalence and mechanisms of the different sulfide dependent pr…
Hydrogen sulfide was found to be more toxic to hippocampal slice cultures than isolated hepatocytes. Chloride ion channel blockers decreased H 2S cytotoxicity suggesting that H2S enters the cells via these channels. Intracellular H2S was formed from cysteine, metabolism as the c…
Volume 61 of Reviews in Mineralogy and Geochemistry presents an up-to-date review of sulfide mineralogy and geochemistry. The crystal structures, electrical and magnetic properties, spectroscopic studies, chemical bonding, thermochemistry, phase relations, solution chemistry, su…

Teeming with weird and wonderful life--giant clams and mussels, tubeworms, "eyeless" shrimp, and bacteria that survive on sulfur--deep-sea hot-water springs are found along rifts where sea-floor spreading occurs. The theory of plate tectonics predicted the existence of these hyd…
