Both siltstone and limestone, like almost all sedimentary rocks, can only form underwater. Siltstone is, as the name suggests, composed of tiny particles of silt, compacted over time into rock. Since Indiana siltstone contains a high concentration of durable silica particles, this rock is harder than the surrounding limestone – hence the less ...

The water pressure compacts the sediment, creating limestone.

Sedimentary rock - Limestones, Dolomites, Carbonates: Limestones and dolostones (dolomites) make up the bulk of the nonterrigenous sedimentary rocks. Limestones are for the most part primary carbonate rocks. They consist of 50 percent or more calcite and aragonite (both CaCO3).

It is usually almost pure white, and can be crushed in your …Stalagmites and stalactites form when water passes through bedrock and picks up calcium and . carbonate ions. When the chemical-rich water makes its way into a cave, the water evaporates and leaves behind calcium carbonate on the ceiling, forming a stalactite, or on the floor of the cave, creating a stalagmite.Limestone is an example of an organically formed sedimentary rock.

It is relatively soft and can be scratched with a penny, but will usually scratch your fingernail. Limestone will react and fizz with a weak acid like white vinegar. Fossils, shell fragments, and coral are common.Two processes form limestone: (1) biogenic condensation from saltwater, with organisms that secrete lime and foraminifera as the main mechanisms; and (2) mechanical movement and deposition of preceding limestones, which results in clastic deposits.
