Data for Magma emplacement depth controls the Cl signature of assimilated crust and global MORB Cl variability

The supplementary tables contain a range of analytical data essential to the manuscript of Magma emplacement depth controls the Cl signature of assimilated crust and global MORB Cl variability. These include encompass sample information, reference material analytical results, and fluid inclusion data for Onnuri hornfelsic diabase. They also detail major element and chlorine compositions of CIR Segment 3-2 MORB, and amphiboles from Onnuri gabbro and diabase. Additionally, whole-rock trace element data for Onnuri diabase, oxygen isotope data for Onnuri hornfelsic diabase, and clinopyroxene and plagioclase major element compositions for Onnuri hornfelsic diabase are provided.
