Production of $^3$He in Rocks by Reactions Induced by Particles of the Nuclear-Active and Muon Components of Cosmic Rays: Geological and Petrological Implications [PDF]

open access: yesPetrology, 2016, Vol. 24, No. 1, pp. 21-34, 2016
The paper presents data on the production of the $^3$He nuclide in rocks under the effect of cosmic-ray particles. The origin of the nuclide in the ground in neutron- and proton-induced spallation reactions, reactions induced by high-energy muons, and negative muon capture reactions is analyzed.

Metamorphic Rocks, Ireland [PDF]

open access: yesNature, 1880
THERE appears to be confusion as to the times when metamorphic action occurred among the Irish rocks; my experience would point to the following:—

Beyond adaptive preferences: Rethinking women's complicity in their own subordination

open access: yesEuropean Journal of Philosophy, Volume 30, Issue 4, Page 1317-1334, December 2022., 2022
Abstract An important question confronting feminist philosophers is why women are sometimes complicit in their own subordination. The dominant view holds that complicity is best understood in terms of adaptive preferences. This view assumes that agents will naturally gravitate away from subordination and towards flourishing as long as they do not have ...

Evidence of Permian magmatism in the Alpi Apuane metamorphic complex (Northern Apennines, Italy): New hints for the geological evolution of the basement of the Adria plate [PDF]

open access: yes, 2018
The occurrence of metavolcanic rocks within the Paleozoic basement of the Alpi Apuane metamorphic complex has been known since long time. Among them, some massive porphyritic tourmaline-bearing rocks cropping out in the southern sector of the Alpi Apuane present some distinctive and peculiar features, differing from the better known middle Ordovician ...

An atomic perspective on the serpentine-chlorite solid-state transformation [PDF]

open access: yesarXiv, 2021
Serpentine minerals are important components of metamorphic rocks and promising geo-materials for nanotechnology. Lizardite, the most abundant serpentine mineral, can be transformed into chlorite during metamorphism. This intriguing phase transformation should affect the deformation behavior during aseismic creep and slow slip at the base of the ...

Comparison between 2D and 3D microstructures and implications for metamorphic constraints using a chloritoid–garnet-bearing mica schist [PDF]

open access: yesEuropean Journal of Mineralogy
Despite the fact that rock textures depend on the 3D spatial distribution of minerals, our tectono-metamorphic reconstructions are mostly based on a 2D visualisation (i.e. thin sections).

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

open access: yesThe Anatomical Record, EarlyView.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

Mineral Characteristics and Metamorphic Evolution of Pelitic Gneiss in Wulashan Area, Central Inner Mongolia

open access: yesKuangchan zonghe liyong, 2023
Wulashan Neoarchean peliticgneiss is exposed in the eclogite gneiss formation of Wulashan group in central Inner Mongolia. It is the most widely distributed plutonic metamorphic rock in Wulashan formation.

The Composition of Zircon and Igneous and Metamorphic Petrogenesis

open access: yes, 2003
Zircon is the main mineral in the majority of igneous and metamorphic rocks with Zr as an essential structural constituent. It is a host for significant fractions of the whole-rock abundance of U, Th, Hf, and the REE (Sawka 1988, Bea 1996, O’Hara et al ...

Remote Sensing Analysis and LiDAR Experimenting in the Espique Valley (La Peza, Granada, Spain)

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT The Espique valley is a small space at the foot of the mountain, practically closed, which hides a rich archaeological heritage, not only of habitats but also of varied productive spaces. For some years now, MEMOLab UGR has been carrying out research that is now enriched with the contribution of LiDAR, with whose application we are ...
