GEOLOGY Of THE
BINGHAM DISTRICT
An Important Work About to be
Issued by United States
Geological Survey,
MESSRS. KEITH AND EMMOAS.
Make Contributions, Also Prof J. ~
Boutwell~-Gc Genesis OF Ore

Tho field work Of which this report
represents The hnnl results was iret
undertaken IN the summer of 1900,
owing 20 the fact that the geological
structure ~ this district proved 10 be-
UNEXPECTEDLY intricate, the work ~
investigation has been more proc
longed than WAS nj ilrst expected,
while the delay Ia cause Tor regret,
this regret N much tempered by the
consideration that had tho report
been published earlier many lmpor-
tani facts brought 10 light durmR the
vigorous development NJ the region IN

THE OLDEST CAMP,
Bingham IN the Oldest aud largest
copper producing camp In Utah, II is
situated IN the north.central part OF
The state IN the Oquirrh mountains, 20
miles southwest Of Ralt Lake city, The
mnin slopes Of the OquITrhe which
rise steeply from elevations Of about
b,0Oo feet on tho surrounding descrte to
elevations OF 10000 feet on the main a.

name TO the mining district Its drain

1ng localities which constitute the
Bingham district, an obong area OF
about ~ square miles.
This region haa been the center ~ a
complex succession Of geological actiy.
tiles which have resulted IN the dopo.
sltlon Of valuable ore bodies. The
sodimcntary country rock has suffered
extensive intrusion, intense assuring,
and partial burial beneath a latte

fhe localities which have undergone the
most intense intrusion and assuring.
Outside the limits Of the comparative.
ny small area that IN characterized by
The combined effects ~ these several
activities ore deposits have not been
found.
The present output conssta almost
entirely Of low'pridc pyrltous conner
ore with comparatively small amounts
Of enriched hlgh-grade black copper

The daily output OF tho camp N about
5000 tons, which is produced almost on.
