The nature of the rocks reveals their origins. Geologists believe that "the present is the key to the past." After observing lava erupting from a present-day volcano or limestone forming in marine waters, we infer that similar types of ancient lavas or ancient limestones formed in virtually the same ways.How do limestones form? • Most limestones are simply the cemented remains of marine shells • Limestone “anatomy” – Grains • Skeletal particles, ooids, peloids – Lime mud • Microscopic crystals produced by calcareous algae and through abrasion of larger particles – Cement • Inorganically precipitated CaCO3 crystals 8.

Modern carbonate sediments are generated in a variety of environments: continental, marine, and transitional, but most are marine.Oolitic limestones are also relatively lightweight, with a density that ranges from 2.5 to 2.7 g/cm3. One of the most interesting physical characteristics of oolitic limestones is their porosity. Due to their unique composition and texture, oolitic limestones are highly porous and can be used as a natural filter for water. passport applying feesfred vanfleet Sedimentary rock - Limestone Formation, Calcium Carbonate, Fossils: Limestones originate mainly through the lithification of loose carbonate sediments.

Oolite is a sedimentary rock made up of ooids (ooliths) that are cemented together. Most oolites are limestones — ooids are made of calcium carbonate (minerals aragonite or calcite ). Ooids are spheroidal grains with a nucleus and mineral cortex accreted around it which increases in sphericity with distance from the nucleus.Limestones weather to produce something called karst topography, where sinkholes and generally bumpy landscapes form. There may be losing streams: streams that lose water from their beds to the underlying water table through cracks and pathways in their stream beds.
