Tonto Basin Postergrie.
Just N. of Delokey Basin there are several hundred feet
of much folded quartzite of probable Postergrie age (157).
Where they are overlain by the Cambrian they are faulted.
In northern part of Magatgal Range there is much of these
red quartzites. Here about 1000' of reddish quartzites with
shale partings some of which thicken to worm easter.
At another place about 1000' gray-green shales, followed
by brown quartzite. Has better red, pink green and
yellow pears.
Strike N. 33° E. (dup page 63).
At Natural Bridge on the granite is basal emplaced with
granite breccias up to 2'. This is followed by a thick unit
of auric quartzite.
Natural Bridge is in Pine creek, and here C and
younger formations outcrop.
Arizona has strata much like Natural Bridge.
Pine is in Lupai. To E. is Chin. To N. is Coconino.
Farther north is Kaibab.
