Furthermore, many of the clasts within the matrix consisted of metamorphic rocks including green slate, pyroxenite, metaperidotite, metadolerite, and amphibolite. |
The report stresses the potential of the pyroxenite contact which should be investigated in more details to for skarn or pegmatite related REE mineralization. |
The pyroxenite rock, that hosts the main mineralized zone, is part of the Thetford Mines ophiolitic complex which is well known for its chromium potential. |
Subsequent melting of mica pyroxenite may produce potassic magmas as a result of orogenic or extensional, thermal or bark triggers. |
The first group consists mostly of melagabbro, perkinite and pyroxenite. |
Its lower part displays alternating bands of peridotite, pyroxenite, and dunite, but dunite is dominant throughout most of the unit. |
