Gneiss temperature and pressure
WebTo seek the occurrence of negative delta O-18 magmas in the Neoproterozoic, we conducted in-situ zircon O isotope analysis and U-Pb dating for granitic gneiss from the northeastern Sulu orogen, east-central China. Zircon U-Pb dating yields protolith ages of 753 +/- 15 Ma to 780 +/- 13 Ma and metamorphic ages of 209 +/- 3 to 244 +/- 7 Ma. http://www.actforlibraries.org/how-gneiss-is-formed/
Gneiss temperature and pressure
Did you know?
Gneiss is a common and widely distributed type of metamorphic rock. It is formed by high-temperature and high-pressure metamorphic processes acting on formations composed of igneous or sedimentary rocks. Gneiss forms at higher temperatures and pressures than schist. Gneiss nearly always shows a banded … See more In traditional English and North American usage, a gneiss is a coarse-grained metamorphic rock showing compositional banding (gneissic banding) but poorly developed schistosity and indistinct cleavage. … See more The word gneiss has been used in English since at least 1757.
