Question
In one model, this mineral is theorized to predominantly form in zones where meteoric and marine water are mixed. For 10 points each:
[10h] Name this carbonate mineral whose formation can also be explained using the reflux model. During its namesake process, this mineral is formed by partially replacing calcium ions with magnesium ions in calcite.
ANSWER: dolomite [or dolomitic rock or dolomitization; accept calcium magnesium carbonate; prompt on dolostone with “What mineral is dolostone made of?”]
[10e] Dolomitization is an example of diagenesis, a general series of physical and chemical changes that only occurs in this rock type contrasted with igneous and metamorphic.
ANSWER: sedimentary rocks
[10m] During dedolomitization, calcium ions used to transform dolomite back into calcite often come from beds of this mineral. Alabaster is a powder plaster composed mostly of this soft mineral.
ANSWER: gypsum [or calcium sulfate dihydrate; prompt on calcium sulfate]
