This specimen is mostly rhodochrosite, with lustrous, red-brown crystals forming a flat, two-sided plate. Individual crystals reach about 8 mm. A few white natrolite needles are also present; the largest of these is 1.2 cm. The dark color suggests (to me) that the material might have chemistry somewhere between pure rhodochrosite (MnCO3) and pure siderite (FeCO3). Classic Poudrette Quarry material. No damage.
