Lisone schist = Archeoic of Grand Canyon.
N.W-S.E.
Apache Spring Test seen in Barnes Peak. Usually
but a part of the gnf is present due to the great faulting.
Litology highly variable from place to place.
In the slate quadrangle this gnf is Kallidocopic
in nature from place to place due to the extreme
faulting.
Barnes Peak 5528' high, has granite at base, then
the Apache Spring capped by Slate lie.
Over the granite is the Bearlar cong. 1-6' thick.
A sea deposit derived from granite.
Pioneer shale 200' Dark reddish-brown arenaceous shale. At the base has much granitic feldspar,
but some occurs thin gnf. Has occasional beds
of quartzite up to 18" thick.
Barnes cong. 16-65' thick. Pellets well rounded.
Has red jasper pellets, Pink quartzite pellets, 3
to 4" across. Lie in an argile cement.
Quipring Spring quartzite, 200' thick. Often a
laminated series of pink quartzites.
Romano leans toward the Cambrian age, rather
than Algonkian.
Post Pennsylvanian faulting (normal). Strike of faults
generally N.W-S.E and N.E-S.W.
Following the faulting or accompanying it came
rich forms of detritus. Came in quantity = the
stratified breccia. As sills and into the faults
shoving aside the strata.
