Therefore, both the evidence of the maximum pressures and temperatures experienced by the buried layers can be imprinted in the underlying metamorphic rocks. Hence, the buried depth as well as plausible tectonic settings can be deduced. Altogether with dating techniques, geologists can even determine the time scale of the tectonic events in respect to the metamorphic events. 344: 2309: 2164: 841: 1839: 2825: 466: 20: 2550: 332: 930: 2590: 2563: 747: 1875: 1386: 888: 2767: 2779: 2489: 1887: 1419: 858: 2706: 1028: 1967:(μ), mineral composition (X).
