Calcite grains recrystallize, typically growing larger - increasing in size.Correct!Correct! Limestone grains react to form quartz and feldspars. Quartz grains recrystallize, typically growing smaller - shrinking in size. Clays crystallize to micas, forming a highly foliated, mica-rich rock. Calcite grains are totally dissolved away, leaving only marble mineral crystals.1 / 1 ptsQuestion 2What are two physical differences between chert and limestone - two common chemical sedimentaryrocks - using mineral identification field methods?Select the answer that shows the correct results for both the acid test and the hardness test on chertand limestone, based on their mineralogy. Acid test: chert does not fizz; limestone does fizz!Hardness test: chert is hard; limestone is also hard!
