Radium decay series dating of barite deposition in the Gulf of Mexico
Barite deposits consisting of chimneys and crusts were recently documented and recovered by submersible from hydrocarbon seeps in the Gulf of Mexico offshore Louisiana at water depths of 510-670 m in the Garden Banks and Mississippi Canyon areas. This is the first discovery of barite deposits associated with cold hydrocarbon seeps.
Sedimentation rate as determined by 226Ra activity in marine barite
The decay of 226 Ra with depth, in these samples, is exponential implying that no radium exchange with porewaters occurs after burial. Thus, barite behaves as a closed system below the sediment mixed layer. The absence of 226 Ra exs activity in barite samples older than ∼8000 years, the lack of any detectable 228 Th, 228 Ra, and …

Barite Powder (BaSO4)
Barite Powder (BaSO4) Admin T10:16:34+03:30. Project Description. Barite is a mineral composed of barium sulfate, BaSO4. It is usually colorless or milky white, but can be almost any color, depending on the impurities trapped in the crystals during their formation. Barite is relatively soft, measuring 3-3.5 on Moh's scale of hardness.
