Values reported are for one soil unless the entry under the soils column
lists more than one number, in which case values are averaged for more
than one soil of the same age at at the same study site. Soil identifiers
are listed for most sites, except that for Coyote Mountains (CM) soils,
the geomorphic surface (Q2, etc.) is followed by the total number of soils
of that age used to obtain the average. Sites from published sources are
FW Fortymile Wash; YW Yucca Wash; KC Kyle Canyon; SL Silver Lake; CV Cima volcanics fans; PV Whipple Mountains; WC Wilson Creek; CM Coyote Mountains. S sites are soils collected for this study.Best, minimum, and maximum ages were assigned by references listed in file "dsolproc.doc" for all but the S- soils. Ages of S- soils were assigned by comparisons of soil development index values to those of soils of known age (see files "dsolproc.doc" and "dsindprn.xls").Interval age is the period of time between the formation of one surface and the formation of the next younger surface.
Interval rate is the rate of accumulation of a pedogenic component in a soil or soils on a surface during the time interval between the formation of that surface and the formation of the next younger surface. It is obtained by dividing the interval mass by the interval rate.
* = The values for silt masses and silt accumulation rates for Kyle Canyon
soils actually represent the combined silt plus clay masses and rates.
N.D. = not determined.
