In this study 80 detrital quartz grains coming from 4 sedimentary rocks samples of the Julian Basin (JB) have been analysed. Quartz can incorporate chemical impurities as defects in the crystal lattice, with substitution of Si4+ with H+ and Al+3 or B3+, by 4H+, and with LiOH. These substitutions form specific infrared absorption bands that can be investigated and analysed (Stalder & Konzett, 2012). Fourier Transform Infrared spectroscopy of quartz was used to investigate the sample set with interest to its OH defect speciation and content. OH defects are correlated to petrogenetic conditions, and they may be used as a provenance tool (Stalder, 2014). Polarized IR spectra can identify these different substitutions and allow to separate them from molecular water contained in fluid inclusions. Defect water contents were calculated for every different substitution (if present) by integration of the absorption area in the peaks’ regions. Julian Basin is a syn-orogenic basin in South-eastern Alps across Italian-Slovenian border, developed in the Late Cretaceous-Early Eocene. Quartz from the oldest sample (JB1; Maastrichtian) show a pattern suggesting a mixed source between igneous and non-igneous rocks, with a slight predominance of metamorphic material supply. Grains from sample JB17 (Thanetian) show the greatest variability in both defects and water content amount that suggests a different and more complex source. Quartz crystals from samples JB23 and JB26 (Ypresian) show a pattern of water-poor grains suggesting a mainly metamorphic rock type source. The peculiarity of JB17 is confirmed by several different previous studies based on both heavy minerals and geochemistry which demonstrated a strong difference in the supplies in the corresponding time interval (Lenaz et al., 2000; Lenaz & Princivalle, 2002; De Min et al., 2014; Velicogna, 2020).

Diverse detrital quartz supplies in SE Alps: an FTIR study

Marine degradation polymers seems like a promising substitute to existing plastics issues. Beside the cost issue, the lower thermal stability also cause processing challenges. The CML aims to connect the different stakeholders and find the next generation of plastics materials.
