Abstract
Lamproites are temporally and spatially widespread; however, they form only volumetrically minor igneous occurrences relative to most, if not all, other mantle-derived alkaline rocks. In fact, all presently known lamproite bodies comprise an aggregate volume of merely 75 km3, corresponding to a sphere with a radius of under 3 km or a 20-m-thick layer spread over Long Island, NY! In common with other alkaline magmas, lamproite melts have formed in the mantle and ascended to the surface over at least the last 1.4 Ga.
Nature goes her own way, and all that to us seems an exception is really according to order.
