Some of these exploration targets consist of old shallow pits, caved shafts and historic shallow underground workings in areas with extensive hydrothermal alteration, hosted by major regional structures in a
felsic volcanic environment.
The NNR is characterized by mafic and
felsic volcanic centers associated with crustal extensions between 15.0 and 16.5 million years old.
The massive sulphide zones occur on the boundary between the
felsic porphyry intrusive and the carbonaceous sediments of the Bottle Creek Formation with significant results from EMDD001 shown in Figure 3 Section AA below.
This volcanic succession hosts Au-rich mineralized sub-volcanic
felsic bodies yielding slightly younger ages and is covered by Paleocene intermediate lavas with hypabyssal intrusions with ages around 48 Ma.
The
Felsic HV family of aluminum electrolytic screw terminal capacitors provides great performances in energy density combined with an ultra-long lifetime.
The property geology contains the contact between Confederation and Balmer Assemblage rock units as well as folded mafic and ultramafic volcanics with mafic and
felsic intrusives also present.
The nature and optical character of the major framework constituents and composition of the heavy mineral assemblage suggest that the sediments were largely derived from acidic (
felsic) igneous rocks.
It contains also some small
felsic enclaves and has sharp contacts with their granitoid host rocks, representing possibly the youngest magmatic unit in the pluton.
Felsic, Mafic and Intermediate are all types of which natural substance?
Dominant classes for GEO arc (predominantly Siluro-Devonian) igneous
felsic intrusive, igneous
felsic volcanic, (Adaminaby Group) marine sedimentary siliciclastic, sedimentary siliciclastic (includes Siluro-Devonian rift basin, Permo-Triassic Sydney Basin and Cenozoic sediments), and to a lesser extent igneous mafic volcanic (Cenozoic basalts) and quartz-rich arenite to rudite (includes Siluro-Devonian rift basin and Permo-Triassic Sydney Basin sediments).
