See more at rock Examples of country rockcountry rock Limited mingling of the gabbroic magma and the partially melted countryrock has produced a contact facies of intermediate composition. The countryrock was typically coarse crystalline granite gneiss, strongly weathered, ventifacted, and partly polished, and outcrops were 'crumbled' and without strength. Weakly oriented phacoid-shaped tectonic slivers of countryrock within the fault zone are in the centimetre to decimetre scale. They start to occur along an approximately straight line without any definable contact between countryrock granite and the matrix of the orbicular rock. Mineral lineations and kinematic indicators in the countryrock imply non-coaxial strain with a shear direction similar to that inferred for the shear zone. At the southern outcrop, a few metres of the contact between the orbicular rock and the countryrock granite are exposed. The intrusion contains abundant megacryst-bearing microdioritic inclusions which are distinct from the countryrock xenoliths that are also sparsely present in the granite. Intruding magma dragged some fragments of this countryrock toward the surface. The problem is exacerbated by the failure of much of the contact profile in the countryrock to yield useful palaeomagnetic data. Wherever the contact is discernible, the granite body shows an intrusive relationship with the surrounding countryrock. The onset of melting in the countryrock is visible in thin-section as the appearance of fine-grained granophyric intergrowths of quartz and feldspar. This pattern is consistent with formation of the trondhjemite from residual melts of the gabbro cumulates, but does not preclude derivation from partial melting of gneiss countryrock. Centimetre/ decimetre-sized metasedimentary countryrock xenoliths are present in the periphery of the pluton. Jarrett has typically incorporated influences as varied as bebop, country, rock, gospel, minimalism, baroque and classical styles into his often lengthy improvisations. The evidence for very brittle veining of the countryrock, and extensive brecciation including fine comminution of quartz, indicates that the veining occurred in a very forceful manner.
