Treiman's Masters Thesis "Precambrian Geology of the Ojo Caliente Quadrangle, Rio
Arriba and Taos Counties, New Mexico."
MS thesis, completed in
1977 at Stanford University, under the kind but sarcastic direction of Dr. R.
(Dick) Jahns. Dick prevented me from mapping the Tertiary and Quaternary rocks
as "Phanerozoic, undivided." Which seemed patently unfair in light of the common
dismissal of ancient rocks as "pre-Cambrian, undivided." The thesis was never published,
and does contain at least one serious error: in the metapelites, I misidentified
cordierite as plagioclase. Enjoy.
