Shallow magma diversions during explosive diatreme-forming eruptions [PDF]
Nature Communications, 2018 Shallow magmatic feeder systems in monogenetic volcanic fields may determine how a volcano erupts. Here, the authors use numerical modeling to show that explosive excavation and infilling of eruptive craters affects local stress states, with feedbacks ...

A compilation and characterisation of lithics in kimberlite and common maar-diatremes and tephra ring deposits [PDF]
Scientific Reports, 2021 Maar-diatreme volcanoes are the second-most common type on land, occurring in volcanic fields within all major tectonic environments. Their deposits typically contain an abundance of lithic fragments quarried from the substrate, and many contain large ...

Emplacement of the Argyle diamond deposit into an ancient rift zone triggered by supercontinent breakup [PDF]
Nature Communications, 2023 Argyle is the world’s largest source of natural diamonds, yet one of only a few economic deposits hosted in a Paleoproterozoic orogen. The geodynamic triggers responsible for its alkaline ultramafic volcanic host are unknown. Here we show, using U-Pb and

Maars to calderas: end-members on a spectrum of explosive volcanic depressions [PDF]
Frontiers in Earth Science, 2015 We discuss maar-diatremes and calderas as end-members on a spectrum of negative volcanic landforms (depressions) produced by explosive eruptions (note – we focus on calderas formed during explosive eruptions, recognizing that some caldera types are not ...

The Pisciarelli main fumarole mechanisms reconstructed by electrical resistivity and induced polarization imaging [PDF]
Scientific Reports, 2021 Pisciarelli, together with the adjacent Solfatara maar-diatreme, represents the most active structure of the Campi Flegrei caldera (Italy) in terms of degassing and seismic activity. This paper aims to define the structure of the Pisciarelli hydrothermal

Potential geological risks from mud diatremes in the orogen regime of Southwestern Taiwan [PDF]
Scientific ReportsIn orogenic regions, faults from plate collisions are the main cause of earthquakes. Recent studies have found that underground mudstone structures and intrusions can accompany fault development, causing surface deformation and geological hazards.

Pristine Early Eocene wood buried deeply in kimberlite from northern Canada. [PDF]
PLoS ONE, 2012 We report exceptional preservation of fossil wood buried deeply in a kimberlite pipe that intruded northwestern Canada's Slave Province 53.3±0.6 million years ago (Ma), revealed during excavation of diamond source rock.

Origin and K-Ar age of the phreatomagmatic breccia at the Trepča Pb-Zn-Ag skarn deposit, Kosovo: Implications for ore-forming processes [PDF]
Geologia Croatica, 2016 The Trepča Pb-Zn-Ag skarn deposit in Kosovo is spatially and temporarily related to the phreatomagmatic breccia of Oligocene age (~23 Ma). The deposit shows features typical for skarn deposits worldwide, including a stage of isochemical metamorphism, a ...
