MECHANICAL PROPERTIES OF GRANULITE FROM HORNÍ BORY IN BOHEMIAN MASSIF

open access: yesGeoScience Engineering, 2019
Granulite represents one of the favourite rock types for the construction of an underground nuclear waste repository in the Czech Republic. Granulite from the Bohemian Massif (locality Horní Bory) was investigated in this study, with a special focus on ...

Petrology of the meta-mafic rocks from the Lolodorf area, Nyong complex (Southwest Cameroon): implication for the origin and emplacement conditions

open access: yesSN Applied Sciences, 2022
Highlights (1) The rocks of the study area consists of fine-grained garnet meta-mafic (FGM) and coarse-grained garnet meta-mafic (CGM) rocks presenting partial melting and metamorphic features characterizing the amphibolite-granulite facies transition ...

Petrology, geothermobarometry and geochemistry of granulite facies wall rocks and hosting gneiss of gemstone deposits from the Mogok area (Myanmar)

open access: yesJournal of Asian Earth Sciences: X, 2023
The Mogok Metamorphic Belt (MMB) of Myanmar formed during the Paleogene collision between the West Burma block and the Shan-Thai block. The MMB is mainly composed of medium to high-grade metamorphic marble, calc-silicate rocks, gneiss, quartzite ...

Evolution of migmatitic granulite complexes: Implications from Lapland Granulite Belt, Part II: Isotopic dating [PDF]

open access: yesBulletin of the Geological Society of Finland, 2006
The migmatitic metapelites of the Lapland granulite belt (LGB) in the NE part of the Fennoscandian Shield represent an arc-related greywacke basin metamorphosed in the granulite facies. Detrital zircons from migmatitic metapelites are derived from 1.94 −

Metamorphic evolution of the Pongomnavolok granulite-enderbite-charnockite complex, Belomorian mobile belt

open access: yesTransactions of the Karelian Research Centre of the Russian Academy of Sciences, 2018
The geological, petrological and mineralogical characteristics of the multi-stage metamorphic evolution of rocks in the Pongomnavolok granulite-enderbite-charnockite (GEC) complex of the Belomorian mobile belt are discussed and the first attempt to ...

The Atlantic granulite belt, Brazil.

open access: yes, 1981
The low- to medium-P Atlantic granulite belt was largely formed at 2700 m.y., but 3100 m.y. ages have been obtained from the granulite belt and adjacent craton.

Ion microprobe (SHRIMP) dates complex granulite from Santa Catarina, southern Brazil

open access: yesAnais da Academia Brasileira de Ciências, 2000
Complex polymetamorphic granulites have been dated in the Santa Catarina granulite complex of southern Brazil through SHRIMP study of zircon. This complex is dominated by intermediate-acid plutonic rocks and contains small volumes of mafic and ultramafic

SECULAR CHANGES IN RELATIONSHIPS BETWEEN PLATE-TECTONIC AND MANTLE-PLUME ENGENDERED PROCESSES DURING PRECAMBRIAN TIME

open access: yesГеодинамика и тектонофизика, 2016
Paradoxically, the lists of “proxies” of both plate- and plume-related settings are devoid of even a mention of the high-grade metamorphic rocks (granulite, amphibolite and high-temperature eclogite facies).

Mechanical properties and local damage evolution of granulite under water-rock interactions

open access: yesYantu gongcheng xuebao
Water-rock interaction is a crucial inducing factor for the damage and instability of surrounding rocks in deep underground engineering. Using uniaxial compression tests, digital image correlation technology, and microstructure tests, this study ...

A Reassessment of Petrochemistry of ~1.2 Ga Tonalitic Rocks of the Northern Tugela Terrane, Natal Metamorphic Belt, South Africa: Further Constraints on the Evolution of This Belt

open access: yesGeological Journal, EarlyView.
Our petrochemical studies on ~1.2 Ga granitoids of the Natal Metamorphic Belt, South Africa, do not suggest any property similar to Phanerozoic‐style subduction‐related granitoids. Plot of Kotongweni Tonalite in Y versus Sr diagram (after Moyen 2011), note that most samples have Sr/Y < 50.
