MgO wt% ≥32% mafic–ultramafic intrusion SOURCE

What is this layer?

Locations and geochemistry for samples with total MgO wt% values ≥32% for mafic ultramafic intrusive rocks. Geochemical data are derived from the Geological Survey of Western Australia geochemistry database (WACHEM) via the Geochemistry — RECALC and Geochemistry — mafic–ultramafic intrusion layers. These samples are more likely to be from cumulate-textured rocks.
