Glass forms when a liquid is fast cooled preventing crystallization, across reversible process known as the glass transition. Organic tissues are commonly preserved by processes of vitrification at very low temperatures, cryopreservation, and can return to their original soft state heated back ambient temperature. It would therefore be impossible find organic embedded in volcanic deposits that have reached several hundred Celsius degrees. Here we demonstrate material with glassy appearance...
The island of Pantelleria is an active volcanic complex, rising 800 m from sea level, situated on a continental rift within the NW sector Sicily Channel (Italy).The characterized by bimodal magmatism, mafic and felsic, with this latter -by far more abundant- including metaluminous trachyte pantellerite (peralkaline rhyolites) magmas, erupted either as lava flows, pumice falls or pyroclastic currents.This scenario, in addition to discontinuous field exposures closely spaced (in space time)...
Abstract Pyroclastic density currents (PDCs) are among the most hazardous of all volcanic processes in terms high speeds and unpredictable extent. While concentrated PDCs usually topographically confined, dilute counterpart (ash cloud) is able to overrun topographic barriers, with unexpected trajectories posing a risk for human settlements around volcano. Here, first time, temperature an ash could, PDC originated during 11 July, 2015 Volcán de Colima eruption, determined, without...
Abstract Diluted pyroclastic density currents are capable to cause huge devastation and mortality around volcanoes, temperature is a crucial parameter in assessing their lethal power. Reflectance analysis on carbonized wood from ancient Herculaneum allowed new reconstruction of the thermal events that affected buildings humans during 79CE Vesuvius eruption. Here we show first PDC entered town was short-lived, ash cloud surge, with temperatures 555–495 °C, causing instant death people, while...
The study of the structural order charcoals embedded in pyroclastic density currents provides information on their emplacement temperature during volcanic eruptions. In present work, a set from three distinct deposits whose temperatures have been previously estimated by charcoal reflectance analyses to lie between 250 °C and 550 °C, was studied means Raman spectroscopy. reveal very disordered ordering charcoals, similar kerogen matured under diagenetic conditions. Changes spectra at...
Detecting the ultrastructure of brain tissue in human archaeological remains is a rare event that can offer unique insights into structure ancient central nervous system (CNS). Yet brains reported literature show only poor preservation neuronal structures. Using scanning electron microscopy (SEM) and advanced image processing tools, we describe direct visualization vitrified spinal cord which discovered male victim AD 79 eruption Herculaneum. We exceptionally well preserved neurons from...
Despite their protracted periods of inactivity, long-dormant volcanoes may be highly hazardous, as reactivation can characterized by violent explosive eruptions. An example such is the Colli Albani caldera, onto which deposits Rome Capital City built, Italy. Its last volcanic activity was voluminous maar-forming phreatomagmatic eruptions dated between 36 and 25ka, but volcano has produced several maar lake overflows during Holocene till historical times. Presently, affected recurrent seismic...
Over 1 million volcanoes on the Earth surface occur in marine and submarine environments different geodynamic contexts [...]
<p>Temperature evaluation of PDCs has been recently performed using optical analysis charred wood (Reflectance - Ro%) embedded within the pyroclastic deposits.</p><p>The validity this proxy for emplacement temperature assessment, established in different case studies (Fogo Volcano, Laacher See volcano, Merapi Colima Doña Juana Ercolano-Vesuvius Volcano), resulting comparable with already well know paleomagnetic...
Abstract Ash cloud surges are capable to cause huge devastation and mortality around volcanoes, temperature is a crucial parameter in assessing their lethal power. Reflectance analysis on carbonized wood from ancient Herculaneum allowed new reconstruction of the thermal events that impacted buildings humans during 79CE Vesuvius eruption. Here we show first pyroclastic flow enter town was short-lived ash surge, detached high concentration currents, with temperatures 555 − 495°C causing...
