The Austrian Dr. Ferdinand Porsche, at age 23, built his first car, the Lohner Electric Chaise. It was the worldâs first front-wheel-drive. Porscheâs second car was a hybrid, using an internal combustion engine to spin a generator that provided power to electric motors located in the wheel hubs.
burial metamorphism. (geology). A kind of regional metamorphism which affects sediments and interbedded volcanic rocks in a geosyncline without the factors of orogenesis or magmatic intrusions. 1  Facebook. 2  Twitter.
138Metamorphism is the isochemical process by which rocks are changed by either heat or pressure, or both heat and pressure. The chemical composition of the parent rock will be the same as the metamorphic rock produced.The rock undergoes the very slow process of solid-state recrystallisation without melting.ifferent temperatures and pressures cause new minerals to grow in rocks that have the same composition. The minerals produced are directly related to pressure and temperature conditions. The lower temperature limit for metamorphism is between 200 and 150 o C. Below these temperatures, changes are part of diagenesis.
