New fission-track results from the northern Chiapas Massif area, SE Mexico: trying to reconstruct its complex thermo-tectonic history

open access: yesRevista Mexicana de Ciencias Geológicas, 2018
The Chiapas Massif Complex, which represents the crystalline basement of the southern Maya block within the North American plate, records numerous thermo-tectonic and magmatic events that occurred in southern Mexico at least since the late ...

Apatite fission track dating of the Beypazarı Granitoid: insight for the inception of collision along the Northern Neotethys, Turkey

open access: yesGeodinamica Acta, 2020
The Beypazarı Granitoid is an arc-related intrusion in the Central Pontides, Turkey. This study presents apatite fission track (AFT) ages of the intrusion to shed some light on collision-related cooling/exhumation history of the central Pontides. The AFT

Two pulse intrusive events of the Pliocene Tanigawa-dake granites revealed from zircon U–Pb dating

open access: yesEarth, Planets and Space, 2021
We performed zircon U–Pb dating on the Pliocene Tanigawa-dake granites (Makihata and Tanigawa bodies) and the Cretaceous Minakami quartzdiorite, Northeast Japan Arc.

Exhumation, crustal deformation, and thermal structure of the Nepal Himalaya derived from the inversion of thermochronological and thermobarometric data and modeling of the topography [PDF]

open access: yes, 2010
Two end‐member kinematic models of crustal shortening across the Himalaya are currently debated: one assumes localized thrusting along a single major thrust fault, the Main Himalayan Thrust (MHT) with nonuniform underplating due to duplexing, and the ...

Biomaterial design strategies for enhancing mitochondrial transplantation therapy

open access: yesBMEMat, EarlyView.
Biomaterials to facilitate mitochondrial transplantation therapy: biomaterials as barriers to protect mitochondria from pathophysiological microenvironments, like osmotic stress caused by the excessive concentration of calcium ion, reactive oxygen species, and advanced glycation end products; biomaterials integrating with biochemical cues to improve ...

Ages on weathered Plio-Pleistocene tephra sequences, western North Island, New Zealand [PDF]

open access: yes, 2001
Using the zircon fission-track method, we have obtained five ages on members of two strongly-weathered silicic, Pliocene-Pleistocene tephra sequences, the Kauroa and Hamilton Ash formations, in western North Island, New Zealand.

A visualization of the damage in Lead Tungstate calorimeter crystals after exposure to high-energy hadrons

open access: yes, 2012
The anticipated performance of calorimeter crystals in the environment expected after the planned High-Luminosity upgrade of the Large Hadron Collider (HL-LHC) at CERN has to be well understood, before informed decisions can be made on the need for ...
