Strontianite and Calcite on Matrix | 215 grams | Mandata, Pennsylvania, USA | SO24 Murchison showing some remnants of fusionThis is a specimen of Strontianite and calcite crystals on matrix from Mandata, Pennsylvania. Strontianite is a rare mineral made mostly of strontium carbonate and is an important source of the metal strontium. It usually forms in hydrothermal veins and limestone deposits, often found alongside minerals like calcite and fluorite. Strontianite can appear in different colors, including white, gray, yellow, green, or brown, and has a glassy or slightly
