Three decent-sized samples; two have red marl dikes bordered by sparry calcite veins Original label: Brocatello limestone with vein of red marl and later vein calcite. In this quarry, calcite is last. Small faults offset calcite at outcrop in some places and show horizontal movement. Most red marl dikes at more or less vertical and horizontal slickenlines are common.
Samples W81-4 through W81-6 see Winterer 1980-1981 notebook page 101.
