The UCS and UTS values for clinopyroxenite and serpentinite falls in category of strong rocks while hornblendite and garnet granulite sample shows relatively weak character.
The Sigula fault-related dyke-like gabbro-diabase is located in the Tallinn domain and the ellipse-shaped Abja quartz monzodiorite lies within the southern Estonian granulite domain (Fig.

The 1,742 Ma age we obtained for the zircon inclusion in the greenish blue sapphire coincides with the age of zircons possibly derived from granulites found, for example, in southern Madagascar (Kroner et al., 1999).
One might suppose that the middle crust in the SG-3 area can be represented by rocks similar in age and composition of the protoliths to the SG-3 Archaean complex but metamorphosed under conditions of high-temperature amphibolite and granulite facies.

According to APEC a detailed exploration programme is being initiated on the property, located to the southeast of Canaco Resources Inc's major gold discovery, which was recognised last summer as a new geological setting (high grade granulite facies metamorphic terrain) that can produce sizable mineralised deposits.

This structure consists of a Proterozoic-age vanadiumrich sedimentary series metamorphosed to the granulite facies but most commonly found as retrograde kyanite-almandine-subfacies rocks of the upper amphibolite facies.
In support of this model, Collins (2002) points out that the mineralogy of many granulite facies complexes requires geothermal gradients between 20[degrees] and 50[degrees]C per km, which is much higher than gradients in collisional environments, but is consistent with those expected in backarc settings.
