  • Dolomite Rock Sedimentary Rocks Sandatlas

    Dolomite rock is a very common sedimentary rock, especially older carbonate rocks (formed before the Mesozoic) tend to be dolomites whereas younger carbonates are predominantly various limestones. Dolomite is usually very similar to limestone and the two are often indistinguishable in the field.

    Dolomitic sedimentary rocks

    " Pure" dolomite resembles micrite, being a fine-grained 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.

    Dolomite Rock History Origin Compare Nature

    Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite. 5.2 Composition 5.2.1 Mineral Content Clay Minerals, Pyrite, Quartz, Sulfides

    Sedimentary rock 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

    Mineralogy: Contains a high proportion of dolomite (the mineral and the rock have the same name). Detrital minerals and secondary silica (chert) may be present. Field relations: Dolomites are usually interbedded with other limestone s and are commonly associated salt and gypsium deposits. Most dolomites are thought to be of secondary (replacement) origin; the calcite of the original limestone

    Sedimentary Rocks University of Pittsburgh

    Carbonate rocks include limestone, which is made of calcite (CaCO 3), and dolostone, which is made of dolomite (CaMg (CO 3) 2). Dolomite often forms when limestone recrystallizes after burial. Many limestones are biochemical; some may be chemical (inorganically precipitated).

    Difference Between Limestone and Dolomite Compare

    03/12/2013· Dolomite is also a sedimentary rock type. When dolomite is formed, several steps of dissolution and re-precipitation is passed where the structure of the mineral is modified into more stable forms and crystallizes in a trigonal-rhombohedral manner.

    Dolomite (Mineral) an overview ScienceDirect Topics

    This is one of the most obvious trends visible in the earth's sedimentary rock record. Its cause has been hotly debated! Some sedimentary petrologists suggest that the progressive increase in the amount of dolomite relative to limestone backward in time implies an atmosphere and/or ocean chemistry earlier in earth history more compatible with dolomite formation (either as primary dolomite, or

    Classification of dolomite rock textures Journal of

    Dolomite rock textures can be classified according to crystal size distribution and crystal boundary shape. The classification scheme presented here is largely descriptive but carries genetic implications because size distribution is controlled by both nucleation and growth kinetics, and crystal boundary shape is controlled by growth kinetics. Size distributions are classified as unimodal or

    5.3: Sedimentary Rocks Geosciences LibreTexts

    In sedimentary rock containing calcite and magnesium (Mg), diagenesis may transform the two minerals into dolomite (CaMg(CO 3) 2). Diagenesis may also reduce the pore space, or open volume, between sedimentary rock grains. The processes of cementation, compaction, and ultimately lithification occur within the realm of diagenesis, which includes the processes that turn organic material into
