Final answer:
Common minerals found in and around playas include calcite, dolomite, and gypsum, which are evaporite minerals resulting from the precipitation in saline waters.
Step-by-step explanation:
The minerals commonly found in and around playas are calcite, dolomite, and gypsum. Playas, also known as dry lake beds, often feature evaporite minerals that precipitate from concentrated saline waters. Among these minerals, calcite (CaCO3) is a carbonate mineral with its clear to white appearance, dolomite (CaMg(CO3)2) is another carbonate mineral typically found alongside calcite, and gypsum (CaSO4ยท2H2O) is a sulfate mineral often observed in its white or clear crystal forms in playa environments.
