Metamorphic rocks are rocks thathave become changed by intense heat or pressure while forming. In the very hot and pressured conditions deep inside the Earth's crust, both sedimentary and igneous rocks can be c
Pyrotechnology for the prehistoric pottery has been an important subject for the study of ancient production technology and technological styles. However, heterogeneous characteristics in chemical and mineralogical compositions and massive amounts of cer
(3) presence of rock assemblages that are characteristic for an ocean-continent transition along either the Adriatic (PLO) or the European (VO) margins, (4) evidence for early accretion to either the Adriatic margin (PLO) during Cre- taceous top-W nappe stacking in the Eastern Alps or ...
rock Fe2O3/(Fe2O3 + FeO) value of 0.1 [103,104,105]; (3) the fluid was considered to be in excess, owing to the observations outlined by [106] that hydrated metabasites contain approximately 5–6 wt.% H2O in the blueschist facies and (4) the bulk-rock compositions used for ...
