Special Issue Information

Dear Colleagues,

Origin and way of transport of volcaniclastic particles through the environments are more than those concerning sedimentary particles, considering that volcaniclastic particles might be produced and transported by primary volcanic mechanisms (sensu White and Houghton, 2006) during explosive eruptions. In most cases, when the transport agent is volcanic (e.g., pyroclastic density currents), particles would travel wrapped into a hot gas medium that, once in contact with water, would react giving rise to a multiple spectrum of depositional features that could potentially result in the obliteration of the primary volcaniclastic origin of particles. Consequent to an eruptive event, large dispersal deposits could potentially enter the sediments’ routing system, giving rise to a series of volcaniclastic and non-volcaniclastic beds during the long-term reapproach of a sedimentary system to pre-eruptive conditions. In other cases, volcaniclastic beds are the simple results of passive erosion, transportation and accumulation of particles from volcanic terranes to depocenters. Deep-water basins, the most distal depocenters of a sedimentary system, can host all the aforementioned bed types organized in a wide range of depositional architectures. Eventually, such architectures also potentially interact with non-volcanic sedimentary systems.

This Special Issue aims to bring together works on deep-water volcaniclastic sedimentation in both modern and ancient sedimentary basins, focusing on (but not limited to) impact of volcanic eruptions on sea-floor sedimentary architectures, reconstruction of eruptive series from deep-water sediments, reconstruction of volcaniclastic architectures from seismic data, provenance analyses on tephra fallout deposits recovered in deep-marine realms, impact of volcaniclastic sedimentation on other sedimentary processes (e.g., carbonate accumulation). Papers on the study of volcaniclastic sequences as potential reservoirs for geoenergy and carbon capture and storage will be also welcome.

Manuscript Submission Information

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 submissions that pass pre-check are 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 2400 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.

At least three tephra layers, with ages around 2 Ma, crop out in the Pleistocene marine sequence of the Crotone basin, in southern Italy. We present the petrography and the mineral and glass chemistry of these layers, in order to correlate them with other Pleistocene sequences and, possibly, to identify the volcanic source(s). The oldest layer (a1) contains glass shards with homogeneous rhyolitic composition, together with crystals of ortho- and clinopyroxene, plagioclase and amphibole. The age, petrography and major elements’ glass composition allow for correlation with coeval tephra layers cropping out in the southern Apennines, near the town of Craco, in Valle Ricca, near Rome, and in the Periadriatic basin, in central Italy. Two other younger tephras (a3 and a4) can be distinguished by the absence of hydrous phases in a3 and the occurrence of biotite in a4. They show a higher variability in glass composition, which may be related to multiple volcanic sources. A fourth tephra of unknown position, but probably intermediate between a1 and a3, was also recognized. The volcanic source of the tephra layers was identified in a submerged paleo-arc in the central Tyrrhenian Sea, possibly corresponding to the Ventotene ridge. The paper also provides a dataset of glass trace elements’ composition for future correlations. Full article
