Remobilization of granitoid rocks through mafic recharge: evidence
... Magma mingling and hybridization are significant in that they often indicate mafic recharge of an active felsic magma chamber (Snyder 2000) or partial melting of previously intruded igneous source rocks by reheating, a process that is commonly and hereafter referred to as remobilization (Murphy et a ...

Tectonic–climatic interaction
Tectonic–climatic interaction is the interrelationship between tectonic processes and the climate system. The tectonic processes in question include orogenesis, volcanism, and erosion, while relevant climatic processes include atmospheric circulation, orographic lift, monsoon circulation and the rain shadow effect. As the geological record of past climate changes over millions of years is sparse and poorly resolved, many questions remain unresolved regarding the nature of tectonic-climate interaction, although it is an area of active research by geologists and palaeoclimatologists.
