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.
Dolomite | Formation, Structure, Properties, Uses, & Facts
Dolomite crystals are colourless, white, buff-coloured, pinkish, or bluish. Granular dolomite in rocks tends to be light to dark gray, tan, or white. Dolomite crystals range from transparent to translucent, but dolomite grains in rocks are typically translucent or nearly opaque. The lustre ranges from subvitreous to dull.

Modeling fracture porosity evolution in dolostone
Opening-mode fractures in dolostones buried to depths of ∼1–5. We developed a geometric crystal growth model for synkinematic dolomite fracture fill in fractured dolostones, where periodic incremental fracture-opening events are introduced with concurrent cement growth. We assumed constant temperature and supersaturation …
Limestone – Geology is the Way
Recognition of limestone Limestone can be recognized easily thanks to its effervescent reaction with hydrochloric acid (HCl). Calcite and aragonite, indeed, react with HCl diluted in water at 10% producing CO 2, according to the reaction:. CaCO 3 +2HCl⇌ CO 2 + H 2 O+CaCl 2. Dolomite also reacts with HCl but at such low dilution (10%), the reaction is …
