A vein of crystalline Calcite runs through the shale host rock of this piece. The crystals do not exceed 0.1" (3 mm) but appear to be well-formed. Though most of the exposed ones are damaged, many are protected in hollows. All have a dull, cream coloration and are dimly transparent. A few clusters of radiating strontianite needles are also present. When viewed under UV light, the Calcite glows with a dull yellow color and the strontianite shows up as a brighter white.
