Petro-structural geology of the Eastern Aspromonte Massif crystalline basement (southern Italy-Calabria): an example of interoperable geo-data management from thin section – to field scale

Abstract

The presented maps provide an example of the synoptic display of multi-scale geological features characterizing the tectono-metamorphic evolution of the crystalline basement terranes in a poly-orogenic-multistadial evolutionary scenario. The petro-structural map of the eastern Aspromonte Massif (southern Calabrian Peloritani Orogen) is characterized by a nappe-like edifice composed by the superimposition of three crystalline basement tectonic units which, sharing the same Alpine-Apennine reworking, underwent a different metamorphic evolution, mostly derived from the Hercynian orogenic cycle. This geological framework is completed by the suture deposition of a Oligocene-Miocene syn-orogenic clastic formation, partly roofed by the back-thrusting of a clay-rich mélange. In order to understand the potential relationships within the complex dataset deriving from the geological investigations of this crystalline basement area, a geo-database, capable of handling multi-scale information from field-derived structural data (i.e. foliation, lineation, fold-and fault-related structures) to micro-scale derived ones (i.e. thin-section analysis, electron microscope and microprobe investigations, thermodynamic modeling outputs) has been constructed, according to the international standards using the Geo-Scientific Markup Language developed by the Commission for the Management and Application of Geo-science Information. Proposed outputs will show the relationships between field-related geological features, showing collected samples and the subsequent laboratory investigations. These are fundamental to achieving reliable results in geological contexts, such as those for reconstructing the tectono-metamorphic evolution of crystalline basement terrains.

Submagmatic to Solid-State Deformation Microstructures Recorded in Cooling Granitoids during Exhumation of Late-Variscan Crust in North-Eastern Sicily

“…Both granitoids and host rocks are locally affected by an Alpine overprint, at Ma [67,68] and P-T (pressure-temperature) peak conditions of~0.8 GPa at~600 • C in the southern sector of Peloritani Mountains [26,27,29] that produced pseudotachylytes and cataclastic to mylonitic rocks; furthermore, a weakly metamorphosed Mesozoic-Cenozoic sedimentary cover sandwiched between the Mandanici and Aspromonte units locally occurs ( [26]; and references therein). P-T conditions for the Variscan metamorphism, producing the main field foliation, are in the range of~0.5 GPa at~550-680 • C for the Aspromonte Unit in the Peloritani Mountains [69], similar to those obtained for rocks of the same unit in the Aspromonte Massif (0.4-0.5 GPa at 650-675 • C; [70,71]). Relatively high P peak values of 0.8 GPa at~600 • C~and of~0.9 GPa at~530 • C were obtained by [46,72], respectively, through thermodynamic modelling of garnet phyllites and schists, from both the Aspromonte and the underlying Mandanici Unit.…”

Geo-LiM: a new geo-lithological map for Central Europe (Germany, France, Switzerland, Austria, Slovenia, and Northern Italy) as a tool for the estimation of atmospheric CO2 consumption

“…These kinds of procedure, widely adopted in the literature (Amiotte-Suchet et al, 2003;Donnini et al, 2016;Dürr, Meybeck, & Dürr, 2005;Gibbs & Kump, 1994;Hartmann & Moosdorf, 2012), is different from the one used for geochemical mapping that requires (i) chemical/isotopic analyses of samples collected in the field and (ii) geoinformatic interpolation tools (e.g. Chiprés, Salinas, Castro-Larragoitia, & Monroy, 2008;Fiannacca et al, 2017;McKinley, 2013;Morris, Pirajno, & Shevchenko, 2003;Ortolano, Cirrincione, Pezzino, Tripodi, & Zappalà, 2015;Reimann et al, 1998;Smith, Cannon, Woodruff, Solano, & Ellefsen, 2014).…”

Geology and mass movements of the Licetto River catchment (Calabrian Coastal Range, Southern Italy)

“…The geological setting of the study area is characterized by the presence of different basement units, each with a different tectono-metamorphic evolution arranged in a nappe-pile stack, forming an allochthonous tectonic building piled up in the Oligocene -Lower Miocene (Amodio-Morelli et al, 1976;Cirrincione et al, 2015;Filice et al, 2015;Ortolano, Cirrincione, Pezzino, Tripodi, & Zappala, 2015;Tansi, Muto, Critelli, & Iovine, 2007;Van Dijk et al, 2000), which overthrusted the Mesozoic carbonate Unit of Apennine affinity ( Figure 2). The lower plate outcrops along the Coastal Range in several tectonic windows (Figure 2 (A)), among these the most extensive is represented by the Mt.…”
