New views on Somma Vesuvius subvolcanic system and on mechanism that could increase eruption explosivity by a review and immiscibility in melt inclusions
No full textSomma-Vesuvius (SV) is an active volcanic system in southern Italy that has generated Plinian eruptions during its history as the infamous 79 CE (Pompeii) eruption. Plinian eruptions produced airfall pumice deposits characterized by white pumice clasts in the lower half part, and by grey pumice clasts in the other upper half part.
Plinian pyroclastic deposits are also characterized by the presence of skarn xenoliths. Previous studies on the fluid (FI) and melt inclusions (MI) in the Somma-Vesuvius (SV) skarn xenoliths have widely documented
immiscibility between silicate melt and hydrosaline melt (±aqueous chloride-rich liquid‐carbonate/sulfate
melt). In this study, we recognize a new type of MI namely composite melt inclusions (CMI) hosted in minerals of SV skarn xenoliths previously studied in the literature. In addition to a review of studies about skarn at SV, we
present new microthermometric observations of CMI based on heating experiments using a heating stage. We
heated CMI to complete homogenization at 1080 ◦C, and we cooled the CMI to simulate a natural sequence of
phase appearances during magma cooling. At T around 1060 ◦C the CMI unmixes forming two different silicate
melts. Upon further cooling at around 700 ◦C, the CMI show droplets of chloride immiscible liquids instantly
nucleating. The cooling experiments of CMI from high-T are assumed to reproduce on a small scale the sequence
of magma cooling prior to eruption below SV. In this case, magma could unmix before eruption forming two
different silicate melts producing a chemically stratified reservoir. In support of our heating experiments results
of CMI, the reprocessing of SV bulk rock compositions data highlights that magma feeding interplinian eruptions
is Fe-and P-rich and Si-poor. In contrast, magma feeding Plinian eruptions is Si-rich and Fe-and P-poor. As
experimental studies have demonstrated, immiscibility can occur when one melt is Fe-and P-rich and Si-poor,
and the other is Si-rich and Fe-and P-poor and the transition between the two end members is not gradual,
resulting in a gap of homogeneous intermediate melt
Improved maximum entropy method for the analysis of fluorescence spectroscopy data: evaluating zero-time shift and assessing its effect on the determination of fluorescence lifetimes
No full textA new algorithm based on the Maximum Entropy Method (MEM) is proposed for recovering both the lifetime
distribution and the zero-time shift from time-resolved fluorescence decay intensities. The developed
algorithm allows the analysis of complex time decays through an iterative scheme based on entropy
maximization and the Brent method to determine the minimum of the reduced chi-squared value as a
function of the zero-time shift. The accuracy of this algorithm has been assessed through comparisons
with simulated fluorescence decays both of multi-exponential and broad lifetime distributions for
different values of the zero-time shift. The method is capable of recovering the zero-time shift with an
accuracy greater than 0.2% over a time range of 2000 ps. The center and the width of the lifetime distributions
are retrieved with relative discrepancies that are lower than 0.1% and 1% for the multi-exponential
and continuous lifetime distributions, respectively. The MEM algorithm is experimentally validated by applying
the method to fluorescence measurements of the time decays of the flavin adenine dinucleotide (FAD)
Closed-form solution of the steady-state photon diffusion equation in the presence of absorbing inclusions
No full textWe have developed a theoretical model for photon migration through scattering media in the presence of an absorbing in homogeneity. A closed-form solution for the average diffuse intensity has been obtained through an iterative approximation scheme of the steady-state diffusion equation. The model describes absorbing defects in a wide range of values. Comparisons with the results of Monte Carlo simulations show that the error of the model is lower than 3% for size inclusion lower than 4 mm and absorption contrast up to the threshold value of the "black defect." The proposed model provides a tractable mathematical basis for diffuse optical and photoacoustic tomographic reconstruction techniques
Perturbation approach to the time-resolved transmittance for a spatially varying scattering inclusion in a diffusive slab
No full textIn the framework of the perturbation approach to the diffusion equation, an analytical expression is derived to describe the effects on the time-resolved transmittance due to the presence of a spatially varying scattering inclusion hidden inside a diffusive slab. This formula assumes that the reduced scattering coefficient of the inclusion is spatially Gaussian distributed and complements that obtained for the absorptive case. The accuracy and the application range of the perturbed transmittance are investigated through comparisons with the numerical solutions of the time-dependent diffusion equation given by using the finite-element method. The proposed perturbation model is validated through a fitting procedure that determines the relative error in retrieving the scattering perturbation parameter of the inclusion located at the midplane of the slab. �� 2006 Optical Society of America
