Barite chimneys on the Gulf of Mexico slope: Initial ...

Barite chimneys associated with hydrocarbonrich fluid venting were recently documented and sampled on the Gulf of Mexico slope offshore Louisiana at 510–520 m water depth. The chimneys are dominated by barite associated with minor amounts of pyrite, iron oxide, Mg calcite, and detrital silicates.

ABSTRACT: Massive Barite Deposits on the Northern Gulf

2011-1-11  The northern Gulf of Mexico continental slope is known for its extensive number of . hydrocarbon seeps. Authigenic carbonate and barite frequently occur as products of the . seepage process. Barite (BaSO. 4) is more pervasive than once thought. Seafloor observa­ tions and samples acquired at sites indicate that barite occurs as chimneys, cones ...

Barite Deposits at Hydrocarbon Seeps from Gulf of

2009-12-1  On Gulf of Mexico (COM) continental slope, oxidation of hydrocarbon-rich fluids from the sediment often leads to formation of authigenic carbonates. Barite frequently occurs with these carbonates. The biogeochemical processes involved in carbonate precipitation becoming more understood each year. However, little attention has been focused on barite and comparatively the
