The ownership of the minerals under a given surface, with the right to
enter thereon, mine, and remove them. It may be separated from the surface
ownership, but, if not so separated by distinct conveyance, the latter
includes it.
See:uintaite
Mined rock salt, halite.
The sequential order of mineral deposition during formation of an ore
deposit. CF:paragenesis
Mineral species showing continuous variation in their properties with
change in composition. A series may be complete; e.g.,
tennantite-tetrahedrite, or partial; e.g., iron replacing zinc in
sphalerite. Syn:crystal solution; solid solution. See also:mineral
a. Any mineral that can be distinguished from all other minerals by
current determinative methods. Stokes b. A naturally occurring homogeneous substance of inorganic origin, in
chemical composition either definite or ranging between certain limits,
and possessing characteristic physical properties and usually a
crystalline structure. See also:mineral
A spring whose water contains enough mineral matter to give it a definite
taste, in comparison to ordinary drinking water, esp. if the taste is
unpleasant or if the water is regarded as having therapeutic value. This
type of spring is often described in terms of its principal characteristic
constituent; e.g., salt spring. AGI
A flotation process based on surface-tension phenomena, accelerated by
means of addition to the pulp of small quantities of oil and air in minute
subdivision. Only about 0.1% oil is added, and the pulp is violently
agitated for 1 to 10 min. Innumerable small bubbles of air are thus
mechanically introduced, which join the oil-coated particles. These are
then removed in a spitzkasten. Exposure to the air after this treatment
then aerates any mineral that has not already taken up its oil film, after
which a second spitzkasten treatment removes this. An early name for froth
flotation. Liddell; Pryor, 3
A fine, water-insoluble, inorganic material, used in admixture with solid
or semisolid bituminous materials. ASTM
In metamorphic rocks, lineation of grains of a mineral. Syn:streaking
AGI
See:hatchettine; hatchettite. Also called mountain tallow.
a. Tar derived from various bituminous minerals, such as coal, shale,
peat, etc. Shale tar. Syn:mountain tar
b. See:maltha; pittasphalt.
Term to distinguish true turquoise from odonotolite (bone turquoise).
Specimens of a mineral species with distinctive physical properties due
to: (1) specific history; e.g., Iceland spar, a coarsely crystalline
variety of calcite of optical grade, or (2) small chemical variation;
e.g., amalgam, a mercurian variety of native silver.
See:vein
Water that contains an unusually high percentage of some mineral substance
that gives the water a distinctive taste and sometimes other properties.
Considered to be beneficial in the treatment of various ailments. Also
called spa water. Cooper
See:ozocerite
A form of chemical weathering resulting in the formation of new minerals
that have greater aggregate volumes than the old ones. These expanding
minerals then act as wedges to split adjacent minerals and rocks apart.
AGI
A substance outwardly resembling wool, presenting a mass of fine
interlaced filaments. It is made by subjecting furnace slag or certain
rocks, while molten, to a strong blast. Being both insect proof and
fireproof, it forms a desirable packing for walls, a covering for steam
boilers, etc. Also called mineral cotton, silicate cotton, and slag wool.
Syn:glass wool
a. Waste material in the raw coal that has been removed in a cleaning or
preparation plant.
b. Notably used to describe colliery rejects; also called tailings.
