Automated delineation and morphometry of unclassified subglacial bedforms

open access: yesBoreas, EarlyView.
We present an automated tool for mapping and analysing subglacial bedforms using volumetric obscurance, without classification. Tested on ArcticDEM data, the method produces bedform outlines with 75% correspondence compared to manually digitized maps.

II.—Irish Metamorphic Rocks [PDF]

open access: yesGeological Magazine, 1886
The meeting of the British Association in Montreal gave different Irish geologists facilities for examining the Archæan rocks of Canada and the States, while since then they and also American geologists have had opportunities for studying the Irish Metamorphic rocks; it may therefore be allowable to give an epitome of our knowledge in regard to the ...

Fault Detection Effectiveness of Source Test Case Generation Strategies for Metamorphic Testing [PDF]

open access: yesarXiv, 2018
Metamorphic testing is a well known approach to tackle the oracle problem in software testing. This technique requires the use of source test cases that serve as seeds for the generation of follow-up test cases. Systematic design of test cases is crucial for the test quality. Thus, source test case generation strategy can make a big impact on the fault

New interpretation of the provenance of crystalline material from Oligocene flysch deposits of the Skole Nappe, Poland: evidence from heavy minerals and clasts in the Nowy Borek section

open access: yesGeologos, 2019
The Futoma Member (Oligocene, Rupelian) of the Menilite Formation is present only in the northern part of the Skole Nappe. Some diatomitic layers of this member in the Nowy Borek section contain coarse-grained detrital material composed of a variety of ...

Evidence for ca. 2046 Ma high-grade metamorphism in Paleoproterozoic metasedimentary rocks of the northern Borborema Province, NE Brazil: constraints from U-Pb (LA-ICP-MS) zircon ages

open access: yesJournal of the Geological Survey of Brazil, 2019
This study presents LA-ICP-MS U-Pb detrital zircon ages on a migmatitic paragneiss of the Jaguaretama Complex, northern Borborema Province, NE-Brazil.

‘I like to dance with the flowers!’: Exploring the possibilities for biodiverse futures in an urban forest school

open access: yesChildren &Society, EarlyView.
Abstract This article explores the ways in which ‘forest school’, an educational approach where children engage in creative and play based activities in a ‘natural’ environment, can contribute towards Sustainable Development Goal 15 (SDG 15) by promoting sustainable use of terrestrial ecosystems and by helping address biodiversity loss. Drawing on data

Cool‐season environmental water delivery increases extinction risk for chytrid‐infected amphibians

open access: yesConservation Science and Practice, EarlyView.
We developed a stochastic population model to test the impact of the timing of environmental water delivery on the extinction risk of L. raniformis impacted by amphibian chytrid fungus. Our simulations suggested populations are less likely to go extinct when environmental water is delivered in spring compared to late winter. This outcome indicates that,

Geochemistry and paleotectonomagmatic setting of metabasites protolith from Asalem metamorphic complex (northwest Rasht) [PDF]

open access: yesپترولوژی, 2016
Asalem metamorphic complex consists mostly of metabasite, metapelite and serpentinite. Metabasites display metamorphic features of greenschist and blueschist facies.

Self-Organized Pattern Formation in Geological Soft Matter [PDF]

open access: yesarXiv
Geological materials are often seen as the antithesis of soft; rocks are hard. However, during the formation of minerals and rocks, all the systems we shall discuss, indeed geological materials in general, pass through a stage where they are soft. This occurs either because they are at a high temperature -- igneous or metamorphic rock -- or because ...
