Products of refining of tar, shale oil, and petroleum in which sulfuric
acid reacts to form a sulfonic acid mixture, green acids, and mahogany
acids and salts. Used in the flotation process and in proprietary
collector agents for flotation of iron ores. Pryor, 1
A soil with a pH of less than 7.0. AGI
Steel melted in a furnace with an acid bottom and lining and under a slag
containing an excess of an acid substance, such as silica.
See also:acid process
Related to ability to liberate hydrogen ions to solution, and hence to
electrical conductivity of equivalent aqueous solutions of acids.

a. See:acid-dip survey
b. A severe or decisive trial, as of usability or authenticity.
Long
Water charged naturally with carbon dioxide. Also applied to natural
waters containing sulfur compounds, esp. sulfates.
See also:acid mine water; acid mine drainage.
Needle-shaped.
A mineral aggregate shaped like a cluster of grapes. Also, full of small
kernels like a grape. Syn:acinose; acinous.
a. Grapelike; applied to the structure of clustered mineral aggregates.
Syn:aciniform; acinous.
b. Granulated; like grape seeds; applied to the texture of some mineral
aggregates.
Former name for actinolite.
See:aciniform; acinose.
A little-used term said of strata that have no inclination; horizontal.
Syn:aclinic
See:aclinal
The line through those points on the Earth's surface at which the magnetic
inclination is zero. The aclinic line is a particular case of an isoclinic
line. Hunt
A brown variety of aegirine having pointed terminations.
See also:aegirine; pyroxene.
Mex. Ore containing 50 to 60 oz/st (1.56 to 1.88 kg/t) of silver.
Hess
Used when the term that it modifies designates something that has the
properties, dimensions, or physical characteristics associated with sound
waves. Hy
Any determination of the physical properties or dimensions of a borehole
by acoustical means, including measurement of the depth of fluid level in
a well. AGI
In theory, a log designed to measure the manner in which the energy of
elastic waves is dissipated in passing through rock. Although no practical
log of this type has yet evolved, the belief that a log of this parameter
would permit the estimation of the permeability of formations would seem
to ensure such a development since no log has been developed to record
permeability. Wyllie
The change of speed of sound with frequency. Hunt
The acoustic impedance of a given surface area of an acoustic medium
perpendicular, at every point, to the direction of propagation of
sinusoidal acoustic waves of given frequency, and having equal acoustic
pressures and equal volume velocities per unit area at every point of the
surface at any instance, is the quotient obtained by dividing (1) the
phasor corresponding to the acoustic pressure by (2) the phasor
corresponding to the volume velocity. See also:impedance
