Distribution and Tectonic Setting of Kimberlites,spect of the tectonic setting of kimberlite, Dawson (1970) established that, in the case of the kimberlites of Africa, most kimberlites are confined to the ancient cratons (or areas underlain by the cratons), and that relatively few are to be found in the circum-cratonic fold-belts.

Geology of Kimberlite Intrusions,Kimberlite occurs in diatremes (pipes), dykes and sills of very limited size, and one example of a kimberlite ring dyke is known in Sierra Leone. (The words diatreme and pipe will be used synonymously.)作者: 牽連 時(shí)間: 2025-3-23 18:59
Xenoliths in Kimberlite,Within kimberlite intrusions there are included fragments of a wide variety of rock types. Minerals derived from their fragmentation are incorporated into the host kimberlite, thereby giving it an extremely complex and hybrid mineralogy.作者: 交響樂(lè) 時(shí)間: 2025-3-24 00:50 作者: Unsaturated-Fat 時(shí)間: 2025-3-24 03:48
Introduction,s have received considerable attention from experimental petrologists in connection with the origin of basaltic magmas. The third principal reason for studying kimberlite is its chemistry.

Distribution and Tectonic Setting of Kimberlites,ork. In addition, it is apparent that in many areas, and particularly in the circum-cratonic fold-belts, the intrusion of kimberlite is part of a phase of very limited igneous activity manifested by intrusion of other rare rock-types; brief summaries of this contemporary activity are included below.作者: emission 時(shí)間: 2025-3-25 20:17
Mineralogy of Kimberlites, incorporated from the high-level formations forming the wall rocks of the kimberlite intrusions, and (b) later minerals formed during weathering or percolation of groundwater, it will be appreciated that the mineralogy of individual kimberlites may be extremely variable and complex.作者: prostatitis 時(shí)間: 2025-3-26 02:09
Kimberlite Genesis, it will be seen that the essential problem is the origin of the phenocrysts and the kimberlite matrix itself. In particular, it is the source and reasons for the concentration within the kimberlite matrix of the high amounts of incompatible elements (see Chap. 5, kimberlite geochemistry) that have to be explained.作者: Explosive 時(shí)間: 2025-3-26 06:09
