time great earthquake having
stresses acting in East-West direc-
tions folded the Penrsylvanian
rocks into a series of anticlinal
waves that connected the Llano
mountains of Texas with the Ar
buckle mountains of Oklahoma, and
thus made a great dam which I'M
pounded the permian seas to the
West and made shore line to the
deep seas to the east of said dam.
his series of anticlinal waves arose
higher and higher toward the east
that is in sea level measurements
the easternmost wave was higher
than those to the west OF il; and
streams flowed westward into the
permian seas.
After much time and degradation
OF the land surface and the aggre-
cation OF deposit in the permian seas
second great earthquake with
stresses acting in north-south direc-
tionS broke across the great dam
and formed of the anticlinll waves
many domal structures as now eN-
ist in Central and Northera Texas.
This second earthquake made also
many faults, assures and synclineS
across the great dam and in these
waters of the permain seas flowed
eastward as the streams now flow.
After much time and degradation
of the land surface the field vas COW
cred by the cretaceous seas and ere
taceous rocks were deposited un-
conformably upon all OF the older
rocks OF Central and Northern Tex
as.
That this second great earthquake
was post-permian and pre-cretace-
Gus in time is proven by the fact
that many anticlinal and synclinal
structures formed Of them, while
the cretaceous rocks were not de-
formed by this earthquake.
The field being again emerged
from the seas degrading forces re-
moved and are still removing the
crctaceous rocks and today we find
Pennsylvania rocks uncovered un-
I'll structures are visible.
Since the deposition Of the creta-
ccous rocks there has been slow
subsidence Of the gulf coastal re-
gion, thus causing a small dip of
cretaceous rocks toward the south
east.
There have been also a few small
earthquakes in Central Texas cauS-
ed by slips on old fault lines and
some of these earthquakes have oc-
CURED in recent years, for instance,
one just east Of Fort Worth and one
sixteen miles southeast Of Brown
wood.
These slight carthuaHes have
helped natures hand in removing
crcateous rocks and exposing the
locations of her storehouses OF oil.
The Pennsylvania rocks of Tex
as have been divided into fo"r grand
subdivisions, named from top to
bottom, Cisco" Canon "Strawn"
and Bend formations. he Cisco
is about 800 feet Of thickness
This formation lies below the Wich-
ita-Albany formation of the permain
and it is difficult to locate the di-
yiding line between the two forma-
tionS.
This formation shows on the sur
face in Concho. McCulloch, Cole
man. Callahan, Shackclford. Steph-
ems. Young, Jack, Archer, Clay and
Montague counties.
The canyon formation is about
500 feet of thickness and Is exposed
in Brown. McCulloch, Stephens.
Palo Pinto, Eastland, Young, Jack
and Wise counties.
The Strawn formation has been
reported in Bulletin No. Al, page As, |
as being more than four thousand |
feet" Of thickness by the University
of Texas; but that the mental ma
chine Of said university jumped sew
cral cogs is proven by Bulletin No.
246, page 81, where are displayed
brakes Colorado River Section
and the log of the "Halscli Farm
Well" near Henrietta, Texas; for
this log shows that in drilling 1885
feet of depth the drill cut 1000 feet
Of permian-S00 feet of Cwco,-7OO
feet OF Canyon, all of the Strawn
and Is feet into the Bend; so this
drill record shows the Strawn for
nation to be but 40 feet Of thick
ness.
Brownwood Texas, sits near the
base Of the Canyon formation.
The Bend formation is about LOCO
feet of thickness and the bend lime
was III past enormously reported to
be the "Mississippian Lime" but
the fact is it is the equivalent of
The Big Lime OF Oklahoma and
Kansas.
The Coodport Oil and Gas Com
pany, on the Dow Taylor farm in
section L 3s1w, is drilling at 2,29S
feet in blue shale. This test has had
several nice showings in the way of
small sands within the last 900 feet
of drilling, and the prospects for 4
we'll are favorable.
