Comment: Tucson. Gyrolite often forms nodular aggregates. These aggregates can appear glassy, dull or even fiberous. Unlike other similar looking minerals (such as prehnite or smithsonite), gyrolite usually forms individual nodules as opposed to botryoidal or crustal growths.
Minerals: Calcite (CaCO3) Gyrolite (NaCa16Si23AlO60(OH)8 64(H2O))
