Whole-Rock Geochemical Dataset of Late Variscan Intrusive Rocks from the Serre Batholith (Calabria, Southern Italy)

We present a whole-rock geochemical dataset of late Variscan intrusive rocks and residual anatectic melts from the mid- and lower continental crust exposed in the Serre Massif of Calabria (southern Italy). A total of 74 samples were collected from the main plutonic units and from leucosomes of associated migmatitic metasediments. The composition of intrusive rocks varies from tonalites and quartz-diorites at deeper structural levels, to peraluminous granites at shallower levels. The dataset includes major, trace and rare earth element (REE) analyses obtained using X-ray fluorescence (XRF) and inductively coupled plasma mass spectrometry (ICP-MS). The dataset integrates new and previously published geochemical data into a consistent and reusable format, including sample lo- cations (WGS84), lithological classification and lithostratigraphic attribution. Sampling sites are also provided as a downloadable geospatial (.kmz) file for visualization in GIS platforms. The data are intended to support a wide range of applications, including stud- ies on granitoid magmatism, water–rock interaction processes in crystalline aquifers and raw materials exploration. Therefore, the dataset represents a valuable resource for both fundamental and applied geoscientific research.
