Showcased last year at PCIM Europe, the
Felsic HV aluminum electrolytic screw terminal capacitor is most often used in aviation, military, medical and railway applications.
The MMEs sometimes show core-tail structures, in which the tail displays an S-shaped bend, suggesting that they were at least partly plastic when introduced into the
felsic magma.
The SOM-HGL GEO attribute information supports this interpretation, indicating igneous mafic volcanic rocks dominate, with SOM-HGL 38 containing small areas of marine sedimentary siliciclastic rocks and SOM-HGL 8 containing minor igneous
felsic intrusives.
Barnes, 1986; Bedard, 1994; Charlier et al., 2005; Bernstein, 2006) and if an external component, such as an evolved melt associated with wall rock assimilation or
felsic magma hybridization, plays a major role (e.g.
In Brazil, summit level technique was introduced for the morphologic analyses of Pocos de Caldas alkaline intrusive complex, State of Minas Gerais, in order to examine if the present morphology is originated from a volcanic caldera or differential erosion of
felsic alkaline intrusive rocks.
From visual inspection it appears that the holes intersected the same mineralized system consisting of upper amphibolite-metamorphosed mafic and
felsic gneiss that have suffered intense pre-metamorphic, volcanogenic massive sulphide style ("VMS") hydrothermal alteration which strongly metasomatized the rocks, in some cases transforming them locally to massive actinolite.
Andesitic enclaves have been interpreted as portions of the intermediate magma that did not mix completely (mingling) with the
felsic host lavas.
This is supported by the presence of mainly
felsic volcanic rock fragments and absence of plutonic/metamorphic rock fragments in these sediments.
The TOZ occurs along the Porcupine-Destor Break within a zone of albitized sediments and strongly silicified
felsic porphyries with associated pyrite and arsenopyrite mineralization.
It has light colour, which is caused mostly by its major
felsic rock-forming minerals, quartz and feldspars.
Major and trace element characteristics suggest that protolith sediments for both units were wackes derived from
felsic igneous sources and deposited at an active continental margin.
