Global Distribution & Thickness of Marine Sedimentary Layers
Grain Size Sediment Classification
Grain Size Dependent Transport
Genetic Classification of Sediments
• Terrigenous: from continents
• Biogenous: from biological sources
• Hydrogenous: seawater precipitates
• Sometimes referred to as “authigenic” -- means formed in place
• Cosmogenous: extraterrestrial sources
