an igneous, plutonic rock, of ultramafic composition, with coarse-grained or
phaneritic texture. The mineral assemblage is typically greater than 90%
olivine with minor pyroxene and chromite. Dunite is the olivine-rich
end-member of the peridotite group of mantle-derived rocks.
electro-magnetic.
a coarse-grained intrusive igneous rock composed of greenish-white feldspar
and pyroxene.
prospecting techniques which measure the content of specified metals in soils
and rocks for the purpose of defining anomalies for further testing.
prospecting techniques which measure the physical properties (magnetism,
conductivity, density, etc.) of rocks and define anomalies for further testing.
a ferruginous deposit remaining after the oxidation of the original sulphide
minerals in a vein or ore zone.
intrusive igneous rock similar to granite, but contains more plagioclase than
potassium feldspar. It usually contains abundant biotite mica and
hornblende, giving it a darker appearance than true granite. Mica may be
present in well-formed hexagonal crystals, and hornblende may appear as
needle-like crystals.
a fine-grained metamorphic rock often banded in appearance and composed
chiefly of feldspar, quartz, and garnet.
a term applied regionally to sequences of mafic to ultramafic rocks.
an ultramafic rock that is a variety of peridotite consisting of the minerals,
olivine and low-Ca pyroxene (enstatite), and named for occurrences in the
Harz Mountains of Germany. It commonly contains a few percent
chromium-rich spinel as an accessory mineral.
a rock formed by volcanic or magmatic processes.
to insert, interpose, or interpolate.
being or relating to a crystalline compound in which usually small atoms or
ions of a nonmetal occupy holes between the larger metal atoms or ions in
the crystal lattice.
any of the several different forms of an element each having different atomic
mass (mass number).
the Australasian Code for Reporting of Mineral Resources and Ore Reserves
prepared by the Joint Ore Reserves Committee of the Australasian Institute
of Mining and Metallurgy, Australian Institute of Geoscientists and Mineral
Council of Australia, as amended or supplemented.
a mineral zone that is usually radial about another mineral or at the area
between two minerals. Also known as ‘corona’.
composed of fine, alternating layers of different materials in the form of
lamellae.
a highly weathered red subsoil or material rich in secondary oxides of iron,
aluminum or both, that occurs as a residual product of weathering.
dealing with the lithology of strata and their organization into units based on
the lithological characteristics and the lithological correlations between the
strata.
