How does a fossil limestone become lithified

WebThe main processes involved in lithification are compaction and cementation. Compaction involves squeezing the sediment into a smaller volume by packing the sediment particles … WebThe greater the weathering of limestone, the more CO2 is removed from the atmosphere. As limestone dissolves faster than silicate rocks, the chemical weathering of limestone accounts for more of the total chemical erosion of the land surface than any other rocks, even though much larger areas of the Earth consist of silicate rocks.

WebThe cracks fill with new sediment and become visible veins running through the lithified rock. These dried-out clay beds are a major source of mud chips, small fragments of mud or shale, which commonly become inclusions in sandstone and conglomerate. WebDolostone is composed of the mineral dolomite, (Ca, Mg)CO3, whereas limestone is generally composed of calcite, CaCO3. Dolostone contains more magnesium (a trace impurity in natural calcite) and has a different crystalline structure. Dolomite can form through chemical alteration of limestone by reaction with groundwater bearing magnesium. WebThe lithification event associated with carbonate dissolution and reprecipitation is reflected by a distinct strontium anomaly in the pore waters at a hundred to a few hundreds of meters subsurface depth (Figs. 9.3 and 9.24).The Sr 2+ concentration of biogenic calcite is three to five times higher than that of the inorganic calcite reprecipitated from solution (Baker et … city of maple valley jobs wa
