“…Mineralogical composition of investigated samples confirmed the composition of NYT, mainly phillipsite, chabazite, and analcime, and hydrous aluminosilicates pertaining to the zeolite group, along with feldspars and minor amounts of clay minerals (de'Gennaro et al, 2000). Data from the literature (Morra et al, 2010) state high porosity values for NYT, which is characterized, moreover, by the presence of micropores causing a high capillary absorption of water that allows microbial growth. SEM observations showed that the microbial community is embedded in an exopolysaccharidic matrix that facilitates the establishment of strong bonds between biofilm and substrate (Fig.…”

Campi Flegrei is a large volcanic area situated northwest of Naples, Italy. Two archeological sites, the Sybil's Cave and the Piscina Mirabilis, are artificial caves dug in the yellow tuff and used during antiquity for various purposes. This paper describes for the first time the algal biodiversity of these caves and determines whether environmental factors such as light intensity and humidity are influential in species distribution. A total of twenty-two algal species were identified by molecular methods (18S rDNA); the largest group was Cyanobacteria (eleven species), followed by algae Chlorophyta (six), Rhodophyta (two) and Bacillariophyta (two). Cluster analysis of algal distribution in the caves in relation to light and humidity showed no relevant differences in algal distribution between the two caves. Three different algal groups were identified. The first one includes strains strictly dependent on low humidity, a second cluster was mainly associated with sites where humidity is not a severe constraint, and a third group, mainly represented by filamentous cyanobacteria, is probably dependent on high humidity, since it was detected only at Piscina Mirabilis.

“…Vulture volcano is located close to Apenninian foredeep and the stable Apulian platform. These volcanic complexes were emplaced at the waning stages of the Apennine orogenesis, in a post-collisional tectonic setting (e.g., Avanzinelli et al, 2008;Beccaluva et al, 1991Beccaluva et al, , 2002Conticelli et al, 2009Conticelli et al, , 2010a and references therein; Morra et al, 2010;Moretti et al, 2013). This is a petrogenetic study of Ischian volcanic rocks belonging to different cycles of activity of the volcanic complex, with new comparisons with analogues found in other areas around the Mediterranean Sea, whose mineral assemblages and compositional trends have provided compelling evidence of extreme fractional crystallization towards peralkaline rocks and refilling the uppermost magma reservoirs with highly primitive compositions (Lustrino et al, 2012 and references therein;Melluso et al, 2012a and references therein).…”

Abstract. The lava domes in the northwestern (Cuma), northern (Punta Marmolite) and central (Accademia) parts of the Phlegrean Fields are the subject of this study. The Cuma and Punta Marmolite trachyphonolitic lava domes are among the oldest Phlegrean products cropping out. The Cuma rocks have an agpaitic groundmass, with early alkali feldspar, Fe-rich clinopyroxene, Fe-edenite and sodalite and late rosenbuschite, fluorite, baddeleyite, pyrochlore, britholite, monazite, aegirine (often Zr-rich) and exceptionally Fe–Mn-rich olivine. The bulk-rock compositions at Cuma have some of the highest concentrations of Zn, Mn, Zr, Nb, Th, U and lanthanides among the Phlegrean Fields rocks, and some of the lowest MgO, P2O5, Sr, Eu and Ba. The Punta Marmolite dome is chemically less evolved, and lacks characteristic agpaitic minerals, but features alkali feldspar, sodalite, nepheline and relatively Na-poor, Fe-rich hedenbergite, with rare Ca-rich plagioclase xenocryst cores. The Accademia dome, belonging to the recent activity, is latitic to trachytic in composition, has highly forsteritic olivine (with chromiferous spinel inclusions), calcic plagioclase and Mg-rich diopside (± phlogopite) xenocrysts in an evolved host rock (with phenocrysts and microlites of alkali feldspar, Fe-rich clinopyroxene, Fe-rich amphibole, magnetite, Fe-rich olivine and accessory baddeleyite, zirconolite and fluorite). There is clear evidence of open-system magma crystallization in the form of interaction between a crystallizing, primitive shoshonitic basalt in a reservoir already filled by rather evolved trachytic magma. The magmatic evolution towards the evolved compositions is dominated by crystallization of more and more Na-rich alkali feldspar in a Cl-, F-rich and relatively H2O-poor environment. Input of mafic magma is evident in many trachytic eruptions of the Phlegrean Fields and even in the products of the Campanian Ignimbrite, but eruptions having mineral assemblages rich in xenocryst phases as well as eruptions virtually free of mafic magma input are also frequently observed throughout the history. This suggests a variable pattern of open- and closed-system crystallization, which may or may not be linked to explosive activity, and that can be caused by intermittent supply of basaltic magma from depth
