Experimental study and weighting analysis of factors influencing gas desorption

open access: yesFrontiers in Earth Science, 2023
Gas is one of the necessary contributing factors for coal and gas outburst accidents, and the gas desorbed in coal is the energy carrier in the outburst process.

The 1.79 Ga Särkilahti leucogranite – a horizontal magma layer below granulite-grade migmatites in SE Finland [PDF]

open access: yesBulletin of the Geological Society of Finland, 2019
The heterogeneous, peraluminous Särkilahti garnet-cordierite leucogranite occupies ~ 75 km2 area in Svecofennian granulite-grade terrain of SE Finland. Country rocks are metasedimentary garnet-cordierite-biotite migmatites with some orthopyroxenegarnet ...

Metamorphic IOTA [PDF]

open access: yes, 2019
IOTA opened recently a new line of research in distributed ledgers area by targeting algorithms that ensure a high throughput for the transactions generated in IoT systems. Transactions are continuously appended to an acyclic structure called tangle and each new transaction selects as parents two existing transactions (called tips) that it approves.

High‐grade metamorphism and partial melting of basic and intermediate rocks

open access: yes, 2016
Rocks of basic and intermediate bulk composition occur in orogenic terranes from all geological time periods and are thought to represent significant petrological components of the middle and lower continental crust.

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 ...

Metamorphic evolution and U-Pb zircon SHRIMP geochronology of the Belizário ultramafic amphibolite, Encantadas Complex, southernmost Brazil

open access: yesAnais da Academia Brasileira de Ciências, 2003
The integrated investigation of metamorphism and zircon U-Pb SHRIMP geochronology of the Belizário ultramafic amphibolite from southernmost Brazil leads to a better understanding of the processes involved in the generation of the Encantadas Complex ...

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.

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.
