Areas where geologic conditions are more favorable for current underground mining technology in the Kaiparowits Plateau study area, southern Utah (kaisumg )

This is a coverage that shows areas in the Kaiparowits
Plateau where geologic conditions in the Calico and
A-sequences are more favorable for current underground
mining technology (Hettinger and other, chap. T). This
coverage contains numerous attributes of information. It was
compiled by computing the geometric intersection of nine
polygon coverages using the ARC/INFO UNION command. This
coverage is characterized as being a GUIDE TO WHERE THE MORE
FAVORABLE COAL AREAS ARE LIKELY TO BE for current
underground mining technology: areas where coal beds in the
Calico and A-sequences are greater than 3.5 feet thick, less
than 3,000 feet deep, and inclined by less than 12 degrees,
as described in Hettinger and others, 1999. Additional work
is required to determine the mineability and economics of
these coal deposits.

The outside polygon defines the base of the coal-bearing
Calico and A-sequences of the Straight Cliffs Formation east
of 112 degrees of longitude. The northern boundary is
delineated by the Paunsaugunt fault and volcanic rocks of
Tertiary age. This polygon includes areas where the
coal-bearing Calico and A-sequences have been partially
eroded.
