  12. Stoping

    Stoping by Callan Bentley from the GigaPan Torres Del Paine with moonrise by Suk Choo Kim

    When chunks of "host" rock break off from the roof (or walls) of a magma chamber, and become independent liberated bits called "xenoliths."

  23. Interesting contrast / comparison

    Interesting contrast / comparison by Callan Bentley from the GigaPan WV Rt 55 Whipcove Anticline by Alan Pitts

    between weathering 'style' of the outcrop and the clast size of the sediment that is building up in the small "mini-talus" slopes at the base of the cliff.

  25. Synform hinge

    Synform hinge by Callan Bentley from the GigaPan WV Rt 55 Whipcove Anticline by Alan Pitts

    appears to be here. A good place to measure the limbs' strike and dip and then use a stereonet to determine the trend and plunge of the hinge line.
