Taken: July 30, 2014
Caption: The Liberty Pit Exhibit (across parking lot from marker): Silicified Limestone
Additional Description: This boulder was once a gray limestone. It is now silicified, converted to quartz, as a result of the passage of hydrothermal ore fluids rich in silica through the original limestone. Veins of quartz that criss-cross the boulder are further evidence of the movement of those fluids through the rock. If you look very closely, you can see a few scattered patches of fine-grained green garnet created by similar fluids.
