How might a geologist use acid in the field to identify carbonate rocks such as anhydrite and gypsum?

If you put cold dilute Hydrochloric acid on a carbonate rock the acid dissolves the rock and you get bubbles of carbon dioxide in the acid. This reaction will only happen with carbonate rocks.

Where is the gypsum found in the Earth?
Very widely is the short answer. If you have a crack at 'gypsum' in a reference work such as wikipedia, you'll find reference to the caves of giant gypsum crystals in the Naica mine in Mexico. These crystals are up to 12m long, 4m thick, and weigh up to 55 tons! But with a temp of just under 60oC and an RH of >>90%, time to explore is limited. Back to the Q, large evaporite deposits of gypsum are found near the surface of the earth.
What is the difference between Gypsum and Anhydrite?
Anhydrite is formed from dehydrated gypsum or to make it easier to understand when water is added to anhydrite it becomes gypsum as we can see from their chemical formulas [Anhydrite (CaSO4) and Gypsum (CaSO4-2H2O)].

No. Gypsum is a calcium sulfate dihydrate.
Does gypsum fizz in HCL?
No. Gypsum does not fizz in HCl as it is a sulfate, not a carbonate.
