This may in part be attributed to higher crustal heat production. The question of what else might have been different presents a challenge, as the control “everything else being equal” is removed from the experiment. The first section of Memoir 207 deals with mineralogic and petrologic aspects of high-grade metamorphism, including melting and the nature of fluids. Chapters 6 to 13 focus on the Limpopo Complex of southern Africa, with case studies and reviews of its geochronology and crustal evolution, and of the regional structural and burial-exhumation history. Problems of unraveling the effects of successive tectonometamorphic events in a polymetamorphic province are addressed from the geochronologic and the petrologic perspectives. The last two chapters include numerical simulations of lower crustal diapirism in high-grade metamorphism, and a review of tectonic models for the Limpopo Complex. This well-rounded book is relevant to the big question of uniformitarianism in plate tectonics and its effects. |
