Gold and jade are the materials most closely associated with the pre-Columbian civilizations of the Americas—the Olmec, Maya, Incas, Aztecs, and the gold-working cultures of Colombia. But these great cultures also mined and utilized a much wider array of minerals, the creative use of is readily apparent in their remarkable artifacts.
Temperature makes a big difference. The solution in the cave contains both gypsum and the related mineral anhydrite; below 58 degrees C gypsum is more stable than anhydrite. If the temperature drops, the rate slows precipitously to a point where crystals won't form; at much hotter temperatures only smaller crystals can form.
