a. A monoclinic mineral, 8[FeAsS] ; pseudo-orthorhombic, prismatic, and
metallic silver-white to steel gray; the most common arsenic mineral and
principal ore of arsenic; occurs in many sulfide ore deposits,
particularly those containing lead, silver, and gold. Syn:mispickel;
arsenical pyrite; white pyrite; white mundic.

(OH)4 .6H2 O ; typically orange-red.
A main road with secondary roads joining it. Hammond
a. Refers to ground water under sufficient hydrostatic head to rise above
the aquifer containing it. AGI
b. Pertaining to underground water that is confined by impervious rock or
other material under sufficient pressure to raise it above the upper level
of the saturated rock or other material in which it occurs, if this rock
or material is penetrated by wells or natural fissures. Formerly, the term
was applied only to water under sufficient pressure to raise it to the
surface of the Earth. Stokes
An aquifer that contains artesian water. AGI
A geologic structural feature or a combination of such features in which
water is confined under artesian pressure. AGI
The process of discharge from a well by artesian pressure, and also the
quantity of water discharged. The artesian pressure is aided by the
buoyancy of the natural gas that enters some wells with the water.
