These are characterised by soils varying from thick peat to bare granite and tonalite.
12.
The predominate rock type is a white, coarse-grained, foliated hornblende tonalite.
13.
It is paved with tonalite plates.
14.
Likewise, partial melting of eclogite has been modeled to produce tonalite-trondhjemite-granodiorite melts.
15.
The older one consists of granodiorite and adamellite with inclusions of tonalite, diorite, and gabbro.
16.
Migmatised igneous or lower-geochemical signatures and typically plagioclase dominant mineralogy forming monzonite, tonalite and granodiorite compositions.
17.
The most common rock types in plutons are granite, granodiorite, tonalite, monzonite, and quartz diorite.
18.
When a granitoid contains less than 10 % orthoclase, it is called tonalite; pyroxene and amphibole are common in tonalite.
19.
When a granitoid contains less than 10 % orthoclase, it is called tonalite; pyroxene and amphibole are common in tonalite.

The schematic image above right shows two possible flat subduction mechanisms that could create the tonalite plutons seen in the greenstone belt.
