Major, trace element, and isotopic analyses of samples collected during SO299 at Conical Seamount, Papua New Guinea

This dataset contains geochemical measurements from magmatic rocks recovered using a Remotely Operated Vehicle (ROV) during RV Sonne cruise expedition SO299 at the main cone and the Karambusel eruptive center of Conical Seamount, located off-shore Lihir, in the northeast of Papua New Guinea.
Sampling using a ROV ensured precise geological context and reducing sampling bias on steep or unstable volcanic slopes compared to the commonly used dredging methods.
The first part of this dataset integrates whole-rock major and trace element compositions, determined respectively by X-ray fluorescence (XRF) and inductively coupled plasma mass spectrometry (ICP-MS), together with radiogenic isotopic ratios (Sr-Nd-Pb-Hf) analyzed using multi-collector ICP-MS techniques.
The second part of this dataset integrates volcanic glass and mineral major element compositions, determined using electron microprobe (EMP).
Combined with precise location information, these geochemical and contextual data allows to investigate magma genesis, magmatic system evolution, mantle source characteristics and metal enrichment processes at Conical Seamount and specifically at its western-flank Karambusel eruptive center.
