GREAT DEPOSITS
Of FINE MARBLE
Located Five Miles West of
Grandy, Willard County, lust
Over the Nevada Line.

A marble deposit in eastern Nevada
was examined in the fall of 1907 by N. II.
Darton. one of the biologists of the Unit
ed States geological survey at the re-
quest Of J. X. Taylor, supervising archi-
tect of the treasury and a report on the
extent conditions of occurrence and COM
mercial prospects OF the deposit has just
been published by the survey as an ad-
vance chapter from bulletin No. $40,
Contributions to Economic Geology,
1907
The exposures of the marble occur in
one of the numerous canyons that lncise
the rocks of the Snake range in the south
eastern part OF White Pine county and
open out into Snake valley. The particu-
lar canyon Of the marble lies south or
some warm springs, and the exposures
begin at point about five miles west by
south OF Grandy postoffice, in Mlllard
county, Utah, or four miles west of the
NeYada-Utah state line. For two miles
the marble constitutes the greater part of
the walls of the main canyon and also OF
several Of its branches, lying throughout
floor, but pitching downward at both ends
of the exposure. The marble member is
about $50 feet thick and is included be-
tween metamorphic schists.
The marble is a completely recrysta lllzed
limestone showing great variety of tints
of various colors. The larger part of the
deposit is a dark blush gray, banded or
notified with light gray or white. A thick
slight but pleasing tinge of cream, oc-
ours in the upper part of the member. In
the western part OF the canyon this white
marble is massively bedded and about
thlrty-fiVe feet thick. Farther east 1t out
crops along the canyon walls at various
elevations, and near the east end of the
canyon, where it passes beneath the sur
face, IL is about thirty feet thick and not
maSSiVely bedded- In an exposure on the
slopes a short distance south of the can
yon, where the marble is brought to the
surface over an area of a few acres, the
rock is pink, in part in general tone and
in part in mottlings, but the extent OF the
pink marble is not revealed
The natural weathered surface indicates
that the rock would weather satistactor-
ily- Its crystalline structure is SO COM
plete that ii takes a beautiful polish, ana
this character appears to extend through
out the entire deposit.
Mr., barton states that the beds are very
favorably situated for quarTying, as they
lie nearly level for long distances and
are presented in sloping canyon walls
The amount of marble is great and there
seems to be no reason why Quarrles prop
erly opened should not be successfully OPP
Grated. The canyon has a good road, over
which the material could easily be brought
on a gentle down grade to the main wagon
road in Snake valley. Thence, however
the distance to railroad is from siXty-flVe
to eighty miles. over mountains or along
valleys. and the expense of haulage
would be great.
Physical tests of four samples of the
marble made at the structural-materlals
testing Laboratories of the survey at St
Louis, showed a crushing strength rang
ing from approximately 1900 TO more
than 10000 pounds per cubic foot The
samples do not: however. indicate the
strength which the quarry material might
be expected to have. as they were all
taken either from outcropping Lodges or
within a few inches Of the surface. Chem
icaI ANALYSES of these four samples were
also made at the ST Louis testing labor
atories. and the results are given in Mr..
Darton's report, copies of which may be
obtained free of charge by applying to
the director of the United States geolog-
zeal survey at Washington, d. c.
