Contact Metamorphism of Pelitic Rocks Constrains the Depth of Emplacement of the Re di Castello Intrusion (Adamello Batholith, Italy)

Journal of Metamorphic Geology, Volume 43, Issue 1, Page 47-69, January 2025.
ABSTRACT Re di Castello is the southernmost unit of the composite Adamello batholith (central Alps, Italy). It was emplaced between 43 and 40 Ma, yet its depth of emplacement is not well constrained. We have studied the contact metamorphism of pelitic country rocks in two localities: the upper Caffaro Valley and the Borzago Valley in the southern and ...

Ultra - high temperature granulite - facies metamorphic rocks from the Mozambique belt of SW Tanzania [PDF]

, 2013
The metamorphic rocks in the Neoproterozoic (Pan-African) Mozambique belt of southwestern Tanzania, around the town of Songea, can be subdivided into one- and two pyroxene bearing charnockitic gneisses, migmatitic granitoid gneisses and amphibolite ...

Age of younger tonalitic magmatism and granulitic metamorphism in the South Indian transition zone (Krishnagiri area); comparison with older Peninsular gneisses from the Gorur-Hassan area [PDF]

, 1993
A major episode of continental crust formation, associated with granulite facies metamorphism, occurred at 2.55-2.51 Ga and was related to accretional processes of juvenile crust. Dating of tonalitic-trondhjemitic, granitic gneisses and charnockites from
