Timing of Metamorphism and Provenance of the Metamorphic Basement of the Xiangshan Uranium Orefield, Jiangxi Province, China
basement metamorphic rock detrital zircon sedimentary provenance Precambrian Jiangnan orogenic belt Xiangshan
2018/4/10
The origin, age and evolution of the Precambrian metamorphic basement of southern China provide useful insights into early crustal development. Here, we present new laser ablation–inductively coupled ...
Elemental transport upon hydration of basic schists during regional metamorphism: Geochemical evidence from the Sanbagawa metamorphic belt, Japan
mass transfer fluid flow hydration metamorphism Sanbagawa belt
2017/4/10
Trace element and Sr–Nd–Pb isotopic compositions of basic schists in the Cretaceous Sanbagawa metamorphic belt, a
typical regional metamorphic belt in the circum-Pacific orogeny, have been investigat...
Shear heating not a cause of inverted metamorphism
Shear heating not a cause inverted metamorphism
2014/4/15
An archetypal example of inverted metamorphism purportedly resulting from shear heating is found in the Pelona Schist of southern California (United States). Recent studies demonstrate that the Pelona...
Evidence of Shock Metamorphism Effects in Allochthonous Breccia Deposits from the Colônia Crater, São Paulo, Brazil
Colô nia Crater Polymictic Allochthonous Breccia Shock Metamorphism Effects
2013/3/11
The 3.6 km-diameter Colonia impact crater, centred at 2352'03"S and 4642'27"W, lies 40 km to the south-west of the São Paulo city. The structure was formed on the crystalline basement rocks and d...
Geochronology of high-grade metamorphism in the Sveconorwegian belt,S. Norway:U-Pb,Th-Pb and Re-Os data
Geochronology high-grade metamorphism Sveconorwegian belt U-Pb Th-Pb Re-Os
2009/12/2
The timing of Sveconorwegian high-grade metamorphism is evaluated in the four lithotectonic units / terranes exposed in the Sveconorwegian belt in South Norway. U-Pb, Th-Pb and Re-Os data were obtaine...
Nitrogen and N-isotope variation during low-grade metamorphism of the Taiwan mountain belt
nitrogen isotope devolatilization subduction zone Taiwan
2017/8/9
To investigate factors affecting the evolution of nitrogen system in rocks during progressive metamorphism, unmetamorphosed to greenschist-facies pelitic samples were collected from both pelitic and (...
Alpine Metamorphism and Granitoid Magmatism in the Strandja Zone: New Data from the Sakar Unit, SE Bulgaria
Strandja zone Sakar unit Alpine tectonics syntectonic granitoids structural geology
2009/7/7
The Strandja Zone is a pre-Cenomanian orogen consisting of three tectonic units: the Veleka, Strandja and Sakar units. The first two units display very low-grade Alpine metamorphism, whereas in the S...

Diagenesis and Metamorphism of Clay Minerals in the Helvetic Alps of Eastern Switzerland
Clay mineralogy Diagenesis Helvetic Alps Incipient metamorphism Switzerland
2011/12/1
Abstract: Helvetic sediments from the northern margin of the Alps in eastern Switzerland were studied by clay mineralogical methods. Based on illite “crystallinity” (Kübler index), the study area is d...
