Dolomite Sedimentary Rock

Sedimentary rock - Limestones and dolomites | Britannica

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.

Sedimentary Rocks: Meaning, Composition and Weathering

10. Weathering of Sedimentary Rocks: Sedimentary rocks are attacked by the same weathering agents (mechanical and chemical) that acted on igneous rocks, but with different results since the sediments themselves become the products of weathering. We know conglomerates are composed of any kind of rock or mineral.

Dolomites | Encyclopedia

Dolomite is one of the few sedimentary rocks that undergoes a significant mineralogical change after it is deposited. Dolomite rocks are originally deposited as calcite/aragonite-rich limestone, but during a process called diagenesis, the calcite and/or aragonite is transformed into dolomite.
