Petrology of the Garnet Amphibolites from the Tejići Village - Povlen Mt., Western Serbia [PDF]

open access: yesGeološki Anali Balkanskoga Poluostrva, 2002
Different metamorphic rocks discovered near the village of Tejići (Povlen Mt., Western Serbia) represent members of the olistostrome mélange metamorphosed during the obduction/emplacement of some still hot ultramafic body. They occupy the area of about 2

A matter of time: The importance of the duration of UHT metamorphism

open access: yes, 2016
The duration of granulite (G) and ultra – high temperature (UHT) conditions in regional metamorphism is critical to arguments regarding the tectonic settings of granulites and their relationships to Supercontinent assembly.

On the significance of short-duration regional metamorphism

open access: yesJournal of the Geological Society, 2016
Short-duration regional metamorphism is a recently observed and poorly understood phenomenon in metamorphic geology. In this review, it is defined as metamorphism on time scales that limit length scales (of the associated thermal anomaly) to ...

Intergranular diffusion rates from the analysis of garnet surfaces: implications for metamorphic equilibration [PDF]

open access: yes, 2017
Novel approaches to garnet analysis have been used to assess rates of intergranular diffusion between different matrix phases and garnet porphyroblasts in a regionally metamorphosed staurolite-mica-schist from the Barrovian-type area in Scotland.

Matching of images based on their diffeomorphic mapping [PDF]

open access: yesКомпьютерная оптика, 2018
We discuss a problem of comparison of two diffeomorphic images, namely, the source and target images of a diffeomorphism, which are given by two sets of points.

Pressure—Temperature—Time Paths of Regional Metamorphism I. Heat Transfer during the Evolution of Regions of Thickened Continental Crust

open access: yes, 1984
The development of regional metamorphism in areas of thickened continental crust is investigated in terms of the major controls on regional-scale thermal regimes.

Amphibole: A major carrier of helium isotopes in crustal rocks [PDF]

open access: yes, 2016
The first evidence for a specific role of amphiboles in He isotope balance of crustal rocks was presented in early contributions by Gerling et al. (1971, 1976).

Metamorphic Testing for Cybersecurity [PDF]

open access: yesComputer, 2016
Testing is a major approach for the detection of software defects, including vulnerabilities in security features. This article introduces metamorphic testing (MT), a relatively new testing method, and discusses how the new perspective of MT can help to conduct negative testing as well as to alleviate the oracle problem in the testing of security ...
