  • Difference Between Limestone and Dolomite | Dolomite vs ...

    Dolomite is also a sedimentary rock type. When dolomite is formed, several steps of dissolution and reprecipitation is passed where the structure of the mineral is modified into more stable forms and crystallizes in a trigonalrhombohedral manner.

  • PA DCNR Geology Rock Types

    Common nonclastic sedimentary rocks are limestone and dolomite. Igneous rocks are formed by the cooling of molten material, either lava (above ground) or magma (underground). They are classified by what minerals they contain and the grain size of the minerals (coarse enough to be seen with the naked eye, or too fine to be seen).

  • Sedimentary rock Wikipedia

    Sedimentary rocks are types of rock that are formed by the deposition and subsequent cementation of mineral or organic particles on the floor of oceans or other bodies of water at the Earth's surface. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of geological ...

  • Sedimentary rock Limestones and dolomites |

    Sedimentary rock Limestones and dolomites: Limestones and dolomites are collectively referred to as carbonates because they consist predominantly of the carbonate minerals calcite (CaCO3) and dolomite (CaMg[CO3]2). Almost all dolomites are believed to be produced by recrystallization of preexisting limestones, although the exact details of this dolomitization process continue to be debated.

    " Pure" dolomite resembles micrite, being a finegrained carbonate rock with conchoidal fracture, although it can be slightly granular too. But dolomite is a secondary rock produced by the chemical alteration of any preexisting carbonate rock, so in fact dolomites can be as diverse as limestone.
