), extracting calcium ions and elevating the residual brine's Mg/CaMg/Ca ratio to drive downward dolomitization.

Characterized by a high-energy outer margin break protected by continuous barrier reefs or ooid shoals. The barrier restricts wave energy, creating a low-energy, restricted lagoon landward where fine micrite and evaporites accumulate. origin of carbonate sedimentary rocks pdf extra quality
