A

Aragonite Group

Answer: Witherite (o) - BaCO3

Cerrusite (o) - PbCO3 (Lead carbonate mineral, usually found in the oxidized zone of lead ore deposits. It is a very common weathering product of galena. Also called White Lead.)
Strontianite (o) - SrCO3 (Mainly found as a low-temperature mineral in limestone and also found as a gangue mineral in sulphide veins. It is almost always fluorescent.)
Azurite (m) - Cu3(CO3)2(OH)2 (A secondary copper mineral frequently found in the oxidized zones of Cu-bearing ore deposits. Occur commonly with malachite)
