Petrogenetic significance of orthopyroxene-free garnet + clinopyroxene + plagioclase [+ or -] quartz-bearing metabasites
with respect to the amphibolite and granulite facies, Journal of Metamorphic Geology.
The host rocks are a series of sheared and altered shales, siltstones and metabasites
within the Mitakoodi Quarzites of the Proterozoic Malbon Group.
Parageneses of Ordoviclan sub-greenschist to greenschist facies metabasites from Wales, U.
Transition from the zeolite to prehnite-pumpellyite facies in the Karmutsen metabasites, Vancouver Island, British Columbia.
Phase relations in metabasites and pressure-temperature conditions at the prehnite-pumpellyite to greenschist facies transition, Flin Flon, Manitoba, Canada.
The graphical analysis of greenschist to amphibolite facies mineral assemblages in metabasites.
The metamorphic metabasites, especially edogites, jadeitites and glaucophanites, have a shock-resistant character particularly useful in an axe.
In Western Provence, tool production from pebbles in metabasites belonging to the blue-schist facies (glaucophanite) has been noted by Ricq-de Bouard (1996).
On Lake Leman, half of the documented littoral sites produced axe-blade rough-outs in different kinds of local metabasites and ultrabasites.
With regard to glaucophanites, epi/mesozonal metabasites and ultrabasites, blanks are always pebbles (when they can be identified).
In western Estonia, metabasites of the amphibolite facies dominate.
Monomineral fractions were separated to study the chemical composition (wet chemical analysis) and properties of the main rock-forming metamorphic minerals separated from metapelites and metabasites (Klein 1986).
