Document Summary

Non-clastic: particles are dissolved products of weathering and erosion that are. Rocks: naturally occurring, mechanically coherent aggregates of minerals or mineraloids. Clastic sediments: particles are physically transported solid fragments produced by. Igneous: rocks formed through solidification of molten (partial or full) magma. Sedimentary: rocks resulting from consolidation of loose sediments. Sediment: loose particulate materials; old rocks, remains/secretions of organisms weathering and erosion of pre-existing rocks precipitated from water by chemical and biochemical reactions. Deposition: (sedimentation) clastic sediments settle out of, & non-clastic sediments precipitate from water, wind, wand ice; usually form layers. Weathering: physical and chemical weathering fracture rocks and convert minerals & rocks to altered solids and solutions. Shoreline: clastic gravel, sand, and mud; carbonate sand and mud (marine env. Terrigenous: erosion of land, volcanic dust/eruptions, river sediment, desert dust. Hydrogenous: (authigenic): dissolved minerals from water by bacteria. Pelagic sediments: slope, rise, & deep-ocean floors (more biogenous) 10 million viruses per drop of seawater- 1/10,000 of a mm diameter.
