METAMORPHIC ROCK CLASSIFICATIONGrade, MetamorphicName, RockDescription, Rock
Metamorphic rock:Metamorphic rock is just one of the three types of rock that is found on Earth. This rock is formed through intense pressure and heat applied to a rock.Answer and Explanation: The rock that has the highest metamorphic grade is gneiss. Gneiss is a metamorphic rock that has ...
The low-grade metasedimentary rocks exposed east and south of the Yuli Belt also preserve late-stage structures that may correlate with structures observed in the higher-grade metamorphic rocks. These rocks were initially interpreted as Eocene (Fig.1) (Stanley et al.1981). Recent U–Pb analyses...

Comparison of the relatively old mineral ages with our new whole-rock age contradicts the conventional assumption that mineral isotope systematics are less robust to later disturbance than whole-rock systematics. However, we argue that extensive retrogression, evident in all lithologies at Gruinard Bay...
