The Geological–Structural Types of Granitoids

Canadian Journal of Earth Sciences, 1974
The existence of five natural geological structural types of granitoids is argued: (1) early orogenic (early folding or intrageanticlinal); (2) late orogenic, including granitoids of block-mountain areas; (3) tele-early orogenic; (4) tele-late orogenic; and (5) cratogenic.The early orogenic granitoids are formed during an early stage of folding (early

Geochronology of the Phanerozoic granitoids in northeastern China

Journal of Asian Earth Sciences, 2011
Northeast (NE) China is characterized by immense volumes of granitic rocks, exposed over an area of200,000 km2. Although the precise geochronological framework was not clear, it was considered thatmost of them were emplaced during the Paleozoic, when ...

Granitoid suites

Geological Journal, 1991
AbstractThe concept of suites within granitoid batholiths must be treated with extreme caution, especially when petrogenic interpretation of identified suites is involved (e.g. infrastructural control of granitoid suite composition). Without stated, necessary, and sufficient operational definitions of the parameters (and their weighting) used in suite ...

Metamorphism of Granitoids

1994
Granitoid rocks comprise granites, alkali-feldspar granites, granodiorites and tonalites, and constitute a large portion of the continental crust. Because the main constituents — alkali-feldspar, plagioclase, quartz, biotite, muscovite, hornblende — are found over a wide range of P-T conditions, this rock group is not a very useful indicator of ...
