Penedo dos Mouros Rock-shelter (Test 1, layer 08): general inventory of the lithic assemblage; two amphibolite
flakes from the resharpening of polished tools not included.
Toussaint and Restrepo (1978) dated a garnet amphibolite
by whole rock K/Ar, obtaining an age of 110 Ma.
16QVRAB006, targeting a resistivity low at approximately 80 m depth, was collared in amphibolite
and transitioned into felsic gneiss at approximately 54m depth; immediately above the mineralized intercept which starts at 59.
Growth of early continental crust controlled by melting of amphibolite
in subduction zones.
Metapelitic rocks containing staurolite commonly occur in medium-P regional metamorphism in the staurolite zone of the amphibolite
facies, where staurolite is associated with almandine, muscovite, quartz and kyanite.
Rocks of the Blues Brook Formation are regionally metamorphosed to greenschist facies and grade into lower amphibolite
facies in the Whycocomagh Mountain area (Armitage 1989; Campbell 1990; Swanton 2010; Swanton et al.

The acoustopolarigrams of gneiss, schist and amphibolite
cubic samples from the Kola superdeep section (5893-9672 m depth range) with a high level of elastic anisotropy are presented in Figure 4.
The rocks of BASD volcanics are mainly basalt andesite and rhyolite flows which are highly deformed and metamorphosed the metamorphism ranges from greenschist to amphibolite
Focal species, community representation, and physical proxies as conservation strategies: a case study in the Amphibolite
Mountains, North Carolina, U.
The dominant lithology encountered during the drilling was a coarse-grained metamorphic amphibolite
facies ultramafic unit.
According to these authors above, igneous rocks of this area occur as small, circular to oval outcrops and include members of the Older granite suite mainly granites, granodiorites and syenites while associated schists in the area are: quartz-biotite schist, amphibolite
schist, muscovite schist and quartzitic schist.
A larger sample of rocks of group B type compositions would be required to determine whether the Vaucluse amphibolite
could be more precisely provenanced.
Aggregates types currently used in Poland for high traffic asphalt mixtures are intrusive igneous rocks: basalt, gabbro, granite, andesite, paleobasalt and amphibolite
A significant portion of the mineralisation sits on the margin of a distinctive amphibolite
rock which has been mapped extensively in the area, providing an excellent target for future exploration.
