Second, micrite reacts with acid, chert does not. Chert forms in many associations, from clastics to carbonates. Cherts typically form in places where clastic influx is low (i.e. clastic starved), or in carbonate environments.

What type of rock reacts to acid?

Calcite reacts strongly with the acid. Limestone, which is mainly composed of calcite (calcium carbonate), will also react strongly. Limestones may contain impurities, however, and less-pure limestones will react less vigorously.

What rocks dont react with acids?

Quartzite: very hard and does not react to acid. You have completed the Metamorphic Rock lab.
