Posts Tagged ‘New Mexico’

Because we’re currently discussing microstructural deformation in structure, I’m going to post another photomicrograph today 🙂   This one is compliments of the 2002 Microstructures class I took with Jane Gilotti at UIowa and is of a mylonite in New Mexico.   The photomicrograph was taken with the accessory plate inserted, which is a bit unusual (I’ll explain why we used it in the answer).   The structure students should:

  1. Identify the minerals present to the best of your ability
  2. Identify what the evidence of deformation is & name each type of microstructure present
  3. Explain why I took this image with the accessory plate inserted

NM-99.   (My notes don’t include how wide the field of view is… hmmm)
