Geology Interview Question:

Which carbonate mineral reacts readily with cool dilute hydrochloric acid to produce visible bubbles of carbon dioxide gas?

Many carbonate minerals will do this. However since this is a chemistry homework question - I'm guessing for GCSE - then almost certainly the answer they are looking for is calcium carbonate, because this equation often needs to be learnt and then perhaps balanced in an exam question.
