The Macelj formation is an informal Eggenburgian-early Ottnangian lithostratigraphic unit that established in the area of Hrvatsko Zagorje Basin, which represented a marginal zone Early Miocene Central Paratethys Sea. Modern studies, as part Geologic Map Republic Croatia 1:50 000 project, yielded new data improves knowledge depositional and stratigraphic characteristics formation. sedimentologi...

Abstract This paper forensically reconstructs the timings, impacts and processes that drove sequence of explosive eruptions La Soufrière, St Vincent in April 2021 using a combination field-based stratigraphy textural dissection deposit character together with contemporary visual observations. Explosive activity on 9 early 10 involved destruction almost all 2020/2021 lava dome, c. 60% 1979 dome ...

We validated the daily formation of increments in otoliths yellow goosefish Lophius litulon using reared individuals to examine growth field. Single, round-shaped core structures were observed 41% sagittae and 73% lapilli. Therefore, lapillar used for further observations increment analysis. The lapillus radius newly hatched larvae was 15.0 ± 1.4 ?m (mean standard deviation) forming hatch check...

The pyroclastic rocks of "The Crater", South Island, New Zealand belong to the Miocene, alkaline basaltic Dunedin Volcanic Group and represent an individual eruptive center with possible multiple vents. Three pyroclastic units have been separated at the study area based on textural and compositional features as well as their stratigraphic positions. The central part of The Crater comprises basa...

Abstract Otolith phenotypic variability was analyzed in the Caucasian bleak ( Alburnus escherichii ) from Selevir Reservoir Turkey. Utricular (lapillus) and lagenar (asteriscus) otoliths were removed, while distinguishing between left right otoliths. All photographed on distal (for asterisci) dorsal surface lapilli) using a Leica DF295 digital camera. morphometrics measured to nearest 0.001 mm ...

Strombolian activity varies in magnitude and intensity may evolve into a threat for the local populations living on volcanoes with persistent or semi-persistent activity. A key example comes from of Stromboli volcano (Italy). The “ordinary” activity, consisting intermittent ejection bombs lapilli around eruptive vents, is sometimes interrupted by high-energy explosive events (locally called maj...

Quarrying for aggregate material at Hornsby in New South Wales (Australia) exposed a >100 m-deep cross-section of the volcanic neck Jurassic diatreme, which extruded through Sydney Basin deposits. The reveals features many scales. Globally, there are very few instances such excellent 3D exposure. It is arguable that this exposure alone makes it geosite international value. However, evaluatio...

The volcanic eruption of Tajogaite in La Palma (Canary Islands, Spain) produced approximately 200 Mm3 fine lapilli and ash. Using this ash (VA) to produce alkali-activated binders (AABs) fosters a sustainable approach binder manufacturing, aligning with the principles circular economy reducing reliance on non-renewable resources. feasibility using VA as sole precursor for formulation AABs was e...

The evolution of the Taiwan orogen, an active arc–continent collision zone between North Luzon Arc (NLA) and Eurasian continent, is recorded in arc volcanic sedimentary rocks from Taiyuan retro-foredeep basin Coastal Range, eastern Taiwan. volcanism northern NLA experienced a magmatic culmination at 9–7 Ma cessation 5.3–4.3 Ma, based on new U-Pb zircon ages. Young ages (1.74, 1.58, <1.2 Ma) low...
