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 ...

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 ...

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.

The Material Basis of 18th‐Century Meissen Porcelain

open access: yesArchaeometry, EarlyView.
ABSTRACT In the summer of 1708, the quest for making hard‐paste porcelain from Saxonian clay and other mineral resources succeeded. This was achieved by applying as its essential ingredient newly discovered pure kaolin from Heidelsberg near Aue, western Saxon Ore Mountains.

Modelling Patterns of Past Inundation Processes Combining Geoarchaeology and Morphometric Hydrological Analysis in the Shashe‐Limpopo Basin, South Africa

open access: yesArchaeometry, EarlyView.
ABSTRACT Riverine and valley systems across the globe have been central to the development of past urban centres. By AD 900, the Shashe and Limpopo Rivers seem to have facilitated the interaction and integration of early farming communities in southern Africa. This paper focuses on the application of geoarchaeological perspectives made available by the

Petrogenesis and evolution of an early Proterozoic collisional orogenic belt: The granulite belt of Lapland and the Belomorides (Fennoscandia) [PDF]

open access: yesBulletin of the Geological Society of Finland, 1984
The tectonic and metamorphic pattern of the Precambrian crust exposed in the eastern Baltic Shield is characterized by two adjacent high-grade belts (Tana and Granulite belts) located between the Archean Inari-Kola craton to the east and the South ...
