Non silicate minerals

What is the difference between calcite and aragonite groups?

They are polymorphs, but calcite is made in low pressures with a slightly lower hardness and is [6] with small cations, while aragonite is made in high pressures with a slightly higher hardness and is [9] with large cations.

What minerals are in the calcite group?

Calcite, siderite, and rhodochrosite. (All trigonal)
