• Aragonite frequently contains sand inclusions. It forms in many environments, but a particularly interesting one is its formation from deposition of hot, mineral-rich springs. The water releases the calcium it contains upon reaching the air, and forms mounds and thick crusts around the springs. When these deposited mounds and crusts are banded, they are sometimes carved and termed "Onyx Marble", "Suisan Marble", "California Onyx", or "Mexican Onyx".
