Heavy mineral associations were analyzed in the 60-250 μm fraction of selected arenites. Samples were crushed and sieved to <4 mm, then disaggregated by etching with 10% hydrochloric acid to remove carbonate and apatite. For gravity separation, tetrabromoethane (density 2.967 g/cm³) was used. The ribbon method was used for quantitative analysis until 200 transparent grains were determined (Gazzi et al., 1973). The transparent heavy mineral assemblage includes rare glaucophane-crossite combined, up to 13% kyanite, and trace amounts of lawsonite, indicating a HP-LT metamorphic source.Values <0.01 = traces9.501440.2592Eastern SardiniaNatural Sciences and Engineering Research Councilhttps://doi.org/10.13039/50110000003803863RGPIN-2024
