URANIUM DEPOSITS IN NORTHWESTERN NEW MEXICO

Uranium data compiled by L. S. Hilpert, 1964. Sources of
geologic data are given on Preliminary geologic map of

the northwestern part of New Mexico, by C. H. Dane and
G. 0. Bachman (U.S. Geol. Survey Misc. Geol. Inv. Map
1-224, 1957). The formational descriptions are virtually
as given by Dane and Bachman, except for deletion of
lithologic details and changes made in some stratigraphic
nomenclature to conform with present usage

‘Deposits yielding a sample analysis of 0.1 percent or more U;O, are shawn by a plain symbol. Deposits yielding

alysis between 0.02 and 0.1 percent U, Ox, or identified by a uranium-bearing mineral, are shown by the same
symbol with the superscript”. Chemical analyses were reported for most samples; only a few samples from deposits
in the lower grade category were determined radiometrically.

LIST OF MINES AND MAP NUMBER

Deposits from which uranium ores were produced before January 1, 1965, have mine
status. In the Ambrosia Lake district, for deposits having a map size larger than the
identifying symbol, or are controlled and worked by more than one company, the symbol
is centered over the working shaft rather than centered over the deposit.
