To see if a rock or mineral is fluorescent, you need a UV light. Simply shine the UV light on it in a dark room and watch for any glowing colors. Not all rocks and minerals will glow, but the ones that do can give clues about their identity. For example, certain types of calcite will glow red or pink under UV light.

Septarian nodules are primarily found in carbonate-rich mudstones. Essentially, the ball of mud cracked at some point and allowed the infilling of the nodule with calcite, generally yellow from iron content. Aragonite is also found in these nodules, often as a brown band around the exterior calcite. Moqui Marbles

Calcite replacement is a common phenomenon in deep volcanic rock and volcaniclastic rock. Calcite may replace phenocrysts in lava and crystal fragments in volcaniclastic rock, and they also replace all types of debris and matrix. Extensive replacement may make the former rock texture unidentifiable or form replaced carbonate rocks.
