Special Issue "Dating Deep-Seated Tectonic Activities with Minerals"
Deadline for manuscript submissions: 31 December 2019
We invite you to submit contributions on quantifying the timing of tectonic activity using radiometric methods. Translating the radiometric data of metamorphic and magmatic rocks into meaningful ages using geological dating processes has been a perpetual challenge. Solid-state diffusion has long been thought to represent the only mechanism of resetting isotope systems in minerals, giving rise to the “cooling age concept”. However, it has become increasingly obvious that dissolution and precipitation processes and connected fluid-associated mass-transfer (in chemically open systems) is a much faster process, effectively resetting the various isotope systems.
Dissolution precipitation reactions are sensitive to stress. As they are dependent on variations in the availability and composition of fluid, which determines the preservation or resetting of an isotope system, the rocks may contain a wide range of (potentially geologically meaningful) geochronological ages, at length scales of hundreds of metres down to micrometres. Thus, combining geochronology with petrology and structural geology opens up new vistas for dating deep-seated tectonic processes.
Structures and petrological data in metamorphic terrain—such as (U)HP-mineral assemblages, migmatitic gneiss domes, and shear-/detachment zones in granulites—demonstrate that the lithosphere was internally deformed over large scales, at all depths. Dating deformation-related structures in metamorphic rocks is important for the understanding of the pathways of lithospheric movements over time and the rheological properties of the crust. We welcome reviews and original papers dealing with all aspects of dating tectonic activities that occurred deep in the lithosphere, particularly (but not solely): (i) dealing with the role of deformation mechanisms (dislocation creep and dissolution precipitation creep) in the resetting of isotope systems; (ii) dating deformation structures in metamorphic rocks responsible for large-scale tectonic movements; (iii) dating episodes and the duration of deep-seated deformation processes; (iv) linking ductile deformation at depths recorded in metamorphic terrains to tectonic processes that shape the earth´s surface; (v) discussing the linkage between ore formation and fluid-assisted ductile deformation/detachment at depths; and (vi) presenting novel methods of the in-situ dating of deformation in metamorphosed rocks.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Minerals is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
