Continental Magmatic Arcs are based mainly on two concepts. One is a general model of isotopic variations of Nd and Sr in the crust and mantle, and the other is the systematics of mixing between the products of the different magma sources in the crust and mantle.作者: 輕浮女 時(shí)間: 2025-3-22 12:45 作者: 名義上 時(shí)間: 2025-3-22 15:48 作者: 種子 時(shí)間: 2025-3-22 20:04
Nd Isotopes as Tracers in Planetary EvolutionThe principles underlying the application of the Sm-Nd radioactive system as a petrogenetic tracer are similar to those of Rb-Sr and U-Th-Pb (Faure 1977). To illustrate, an example is presented of the relationships between isotopic effects, petrogenetic processes, and time.作者: 和諧 時(shí)間: 2025-3-23 00:17
