Initialism of large low-shear-velocity province; a characteristic structure of parts of the lowermost mantle of the Earth.
— (2010) argued that kimberlite eruptions, and thus diamond deposits, occur preferentially within 15° of the edge of the African LLSVP, defined as the –1% ΔVS contour in the deep mantle. They claim that ~80% (1112 out of 1395) kimberlites and related volcanics erupted since ca. 320 Ma lie within this zone, and therefore propose that, in addition to causing hotspots and LIPs, deep-mantle plumes cause this distinctive style of volcanic activity, comprising clusters of pipes, dikes, and sills.
