Qhov chaw tectonic ntawm granite thiab nws cov koom haum nrog cov pob zeb hauv av

Dec 09, 2025

Continental collision zones thiab active continental margins yog lub ntsiab ib puag ncig rau zus tau tej cov pob zeb granite, uas nws spatial faib yog tswj los ntawm:


Paleo-subduction zone melting txheej xwm (piv txwv li, Cenozoic intrusion nyob rau hauv Tibetan Plateau).

 

Sib sib zog nqus melting induced los ntawm crustal thickening nyob rau hauv orogenic siv.

 

Mantle upwelling nyob rau hauv extensional chaw ntawm rift zones.

 

Raws li cov ore tseem ceeb - tsim cov pob zeb niam txiv, cov pob zeb granite yog txuam nrog:

 

Tungsten-Tin deposits: Zoo sib xws nrog S- hom granites sib txawv heev.

 

Beryllium-lithium mineralization: Pom nyob rau hauv pegmatite plhaub nyob rau sab saum toj ntawm A- hom granites.

 

Uranium-thorium anomalies: Enriched nyob rau hauv leucogranites ntawm lig magmatic theem.
