The collision events in the Belomorian Province are represented by high pressure ( 6 12 kbar ) and high temperature ( 500 700�C ) kyanite-facies metamorphism, granitoid magmatism, and the formation of folded nappe structure and granite gneiss domes.

The Hunter-Bowen Orogeny has resulted in the New England Fold Belt, a tectonic accretion of metamorphic terranes and mid-crustal granitoid intrusions, flanked by Permian to Triassic sedimentary basins which were formed distally to the now-eroded orogenic mountain belt.

R . S . Blome Granitoid was made from a mixture of Portland cement and angular granite chips along with other stone and sand, laid down over an appropriately arched prepared road bed followed by a six-inch layer of loose gravel ( macadam ).

The Barberton greenstone belt consists of a sequence of mafic to ultramafic lavas and metasedimentary rocks emplaced and deposited between 3.5 and 3.2 Ga . The granitoid rocks were emplaced over a 500-million-year time span and can be divided into two suites : The tonalite-trondhjemite-granodiorite ( TTG ) suite ( emplaced approximately 3.5 3.2 Ga ), and the granite-monzogranite-syenitegranite ( GMS ) suite ( emplaced approximately 3.2 3.1 Ga ).
