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.
1 Low-grade metamorphism takes place at temperatures between about 200 to 320 o C, and relatively low pressure. 2  Low grade metamorphic rocks are characterized by an abundance of hydrous minerals (minerals that contain water, H 2 O, in their crystal structure).n general, metamorphic rocks do not undergo significant changes in chemical composition during metamorphism. The changes in mineral assemblages are due to changes in the temperature and pressure conditions of metamorphism.
