A possibly orthorhombic mineral, Al12 V8 O37 .30H
2 O ; forms weakly pleochroic yellow flakes in argillaceous
anthraxolitic vanadiferous deposits of Kurumsak and Balasanskandyk,
Karatau, Kazakhstan.
a. A rock or soil is saturated with respect to water if all its
interstices are filled with water. AGI
b. In petrology, applied to minerals capable of crystallizing from rock
magmas in the presence of an excess of silica. Such minerals are said to
be saturated with regard to silica and include the feldspars, pyroxenes,
amphiboles, micas, tourmaline, fayalite, spessartite, almandine, and
accessory minerals, such as sphene, zircon, topaz, apatite, magnetite, and
ilmenite. Also applied to igneous rocks composed wholly of saturated
minerals. CF:undersaturated
c. In fatty acids and other organic compounds, a structure in which each
carbon valence is combined either with a distinct atom or by polylinkages.
Pryor, 3
d. A term describing a membrane that is filled as completely as
practicable with bituminous material.
Air that contains the maximum possible amount of water vapor at that
temperature. The amount of water vapor that will saturate a given volume
of air increases with the temperature. Therefore, if saturated air is
cooled, the excess water vapor condenses in the form of mist.
See also:absolute humidity
A mineral that can form in the presence of free silica, i.e., one that
contains the maximum amount of combined silica. AGI
a. A rock having quartz in its norm. AGI
b. An igneous rock composed chiefly of saturated minerals.
CF:oversaturated rock; undersaturated; unsaturated. AGI
See:water table
The wet unit weight of a soil mass when saturated.
See also:unit weight
That pressure for a given temperature at which the vapor and the liquid
can exist in stable equilibrium. Strock, 2
A monoclinic mineral, Na0.3 Zn3 (Si,Al)4 O10
(OH)2 .4H2 O ; smectite group.
A former name for cadmian metacinnabar.
A tough, compact, and white, greenish, or grayish mineral aggregate
consisting of a mixture of albite (or oligoclase) and zoisite or epidote,
together with variable amounts of calcite, sericite, prehnite, and
calcium-aluminum silicates other than those of the epidote group. It is an
alteration product of plagioclase; once thought to be a mineral species.
A tough, compact, white, greenish, or grayish mineral aggregate, resulting
from the alteration of feldspars, and consisting of albite, prehnite,
zoisite, epidote, and other calcium-aluminum silicates and calcite.
Fay; CTD
The replacement, esp. of plagioclase in basalts and gabbros, by a
fine-grained aggregate of zoisite, epidote, albite, calcite, sericite, and
zeolites. It is a metamorphic or deuteric process and is frequently
accompanied by chloritization of the ferromagnesian minerals. AGI

A frame provided with a number of parallel iron bars that are employed to
saw stone. See also:stone saw
In stonework industry, one who maintains stone cutting saws in operating
condition, replacing broken and bent saw blades from gang saws. Also
called sawmaker. DOT

See:basket
The blasting of oblique, horizontal holes along a face and so cutting a
series of slabs that, in plan, resemble saw teeth. Nelson
