<p>A worldwide compilation of published, geochemical analysis of lamproites and ultra potassic mafic rocks (LUPM) is evaluated in a novel way to compare its regional compositional distributions with those of intraplate basalts. This study compares average and percentile values of 26 LUPM regions with distributions of worldwide intraplate basalt (IPB) values considering continental and ocean island basalts. Anorogenic (LUPMa) and orogenic (LUPMo) types are characterized in terms of major- and trace-elements and Nd-, Pb-, and Sr-isotope compositions. Profiles normalized to the worldwide average IPB composition (WLD) provide high-level distinctions between average LUPM types and IPB. A series of two-dimensional (2D) displays of ternary relationship distinguish the regional LUPM distributions, highlighting outlying and transitional LUPM of Russia and China in relation to IPB and LUPMa and LUPMo groups. IPB distributions show similarities to both LUPMa and LUPMo types in terms of elemental and isotopic compositional distributions. LUPMo form more compact distributions than LUPMa and the two groups are relatively cleanly distinguished by Pb-isotope ternary diagrams and the U-Sr-Rb ternary relationship. The Ce-Yb-Sm and Ce/Yb-Al₂O₃/TiO₂-Hf/Th ternary relationships effectively distinguish the transitional LUPM emplaced in anorogenic setting but with LUPMo characteristics. A petrogenetic model is proposed involving multi-episode metasomatism of the depleted upper mantle permeated initially by sets of veins of hydrous melts from subducted materials in orogenic settings. Subsequently, in anorogenic setting, less-hydrous melts derived partly from ancient subducted crustal slabs in the mantle transition zone, and deep mantle plumes originating from the large low shear velocity provinces of the deep mantle.</p>
