a. Originating at the same time as adjacent material; esp. pertaining to
waters and volatile materials (such as carbon dioxide) entrapped in
sediments at the time the deposits were laid down. AGI
b. Said of fluids derived from the same magma. AGI
Water entrapped in the interstices of a sedimentary rock at the time of
its deposition. CF:interstitial water; formation water. AGI
A device similar to a guide frame for shaker conveyors, but with provision
for insertion of the puller rod. A connecting frame can be inserted
between any two standard trough sections to serve as a substitute for a
connecting trough on single-arm electric or air devices. Jones, 1
A shaker conveyor trough of standard length to which special lugs or
plates have been attached to provide a means of connecting the trough to
the driving arms of the conveyor drive unit. All motion of the conveyor is
transmitted through the connecting trough. The term drive trough is
frequently used for this special type of trough. Jones, 1
The means of supporting connecting troughs where they pass over the drive
unit. The support is attached to the drive unit frame and is designed to
allow the connecting trough freedom of movement in the direction of the
panline. Supports may be of the ball frame, wheel, rolled, or rocker arm
types. Jones, 1
Wire used to extend the firing line or leg wires in an electric blasting
circuit. Atlas
A hexagonal mineral, Cu19 Cl4 (SO4 )(OH)32 .3H
2 O ; having SO4 replaced by NO3 toward
buttgenbachkite; deep blue; formerly known as footeite.
Isothermal construction line between two equilibrated phases.

A polarizing microscope using convergent light with the Bertrand lens
inserted, used to test the interference figures of crystals.
CF:orthoscope
Conrad counterflush coring system
A system, the notable feature of which is the provision of a reversed mud
flush circulation that permits uninterrupted core recovery in the rotary
system of drilling. Sinclair, 2
Mechanized pit digger used in checking of alluvial boring. Five-foot-long
(1.52-m-long) sections of tubing 24 in (61 cm) in internal diameter are
worked into the ground from their mounting on a tractor, the spoil being
at the same time removed by means of a bucket or grab. In suitable ground
50 ft (15.2 m) or more depth has been reached. Pryor, 3
a. Said of a natural group of sediments or sedimentary rocks related to
one another by origin; e.g., a consanguineous association (such as flysch,
molasse, or paralic sediments) interrelated by common ancestry,
environment, and evolution. Syn:consanguinity
b. See:comagmatic
Natural group of sediments or of rocks of related origin. AGI
The genetic relationship that exists between igneous rocks that are
presumably derived from the same parent magma. Such rocks are closely
associated in space and time and commonly have similar geologic occurrence
and chemical and mineralogic characteristics. Adj. consanguineous.

A syn. of sutured, preferred in European usage, but obsolescent in
American usage. AGI
Conserving, preserving, guarding, or protecting; keeping in a safe or
entire state; using in an effective manner or holding for necessary uses,
as mineral resources. Hess
Those properties of the ocean, such as salinity, the concentrations of
which are not affected by the presence or activity of living organisms,
but which are affected only by diffusion and advection. Hy
Jig developed for Mesabi iron ores in which vertical movement of water is
produced by low-pressure inflation and deflation of rubber tubes just
below screens. See also:jig
a. The degree of solidity or fluidity of bituminous materials.
b. The relative ease with which a soil can be deformed. ASCE
c. A property of a material determined by the complete flow force
relation. ASTM
d. The properties of a slip that control its draining, flowing, and
spraying behavior. ASTM
e. Percentage of solids in pulp. Pryor, 3
f. Fluidity. Pryor, 3
The liquid limit, plastic limit, and shrinkage limit. These all apply to
the water content of a clay, each in a certain state as defined by British
Standard 1377. See also:Atterberg limits
In geology, any or all of the processes whereby loose, soft, or liquid
earth materials become firm and coherent. Stokes
