There are three basic types of sedimentary rocks. Clastic sedimentary rocks such as breccia, conglomerate, sandstone, siltstone, and shale are formed from mechanical weathering debris. Chemical sedimentary rocks, such as rock salt, iron ore, chert, flint, some dolomites, and some limestones, form when dissolved materials precipitate from solution.

Limestone is a very common sedimentary rock consisting of more than 50% calcium carbonate. Although it occurs in many different forms, its origins can be traced back to either chemical or biochemical processes that occurred in the geological past, .

Limestone, another type of sedimentary rock, forms under different circumstances than sandstones.

There are many different types of limestone formed through a variety of processes. Limestone can be precipitated from water ( non-clastic, chemical or inorganic limestone), secreted by marine organisms such as algae and coral (biochemical limestone), or can form from the shells of dead sea creatures (bioclastic limestone).

There are three basic types of contacts: Depositional contacts, where a sediment layer is deposited over preexisting rock. Fault contacts, where two units are juxtaposed by a fracture on which sliding has occurred. Intrusive contacts, where one rock body cuts across another rock body.

The largest and most abundant solutional caves are located in limestone. Limestone dissolves under the action of rainwater and groundwater charged with H2CO3 (carbonic acid) and naturally occurring organic acids. The dissolution process produces a distinctive landform known as karst, characterized by sinkholes, and underground drainage.

The characteristics that can be observed and measured in a sedimentary rock to deduce its depositional environment include its lithology (which is essentially its rock type), its sedimentary structures, and any fossils it may contain. The schematic diagram below shows different types of depositional environments.

There are three different types of rocks: Igneous, Sedimentary, and Metamorphic. The difference between each type is in how they are formed. Igneous rocks . Igneous rocks have many distinct characteristics. For example, light-colored igneous rocks are more acidic, and have over 65% silica.
