Thus, assigning " age significance " to a result requires studying the metasomatic and thermal history of the rock, any metamorphic events, and any evidence of fluid movement.
12.
The metamorphic conditions which parallel the deformation increase from west to east and from middle amphibolite to granulite facies . metamorphic event, resulting from probable continental collision . ( Madore, 2001 ).
13.
It was roughly contemporaneous with the Bretonic phase of the Variscan orogeny of Europe, with metamorphic events in southwestern Texas and northern Mexico, and with the Antler orogeny of the Great Basin.
14.
Typical glasses, notably formation of spherulites, of perlite, lithophysae, and low-temperature prehnite-pumpellyite facies sub-seafloor alteration is ubiquitous though often overprinted by later metamorphic events.
15.
According to geologist Stefan Schmid, because the Western Alps underwent a metamorphic event in the Cenozoic Era while the Austroalpine peaks underwent an event in the Cretaceous Period, the two areas show distinct differences in nappe formations.
16.
Zircon also forms multiple crystal layers during metamorphic events, which each may record an isotopic age of the event . " In situ " micro-beam analysis can be achieved via laser ICP-MS or SIMS techniques.
17.
According to a study by Bibikova et al . ( 1999 ), the earliest metamorphic event took place ca . 2.8 Ga . " accretionary environment in the vicinity of the Karelian craton . " ( Bibikova et al ., 1999 ).
18.
Dating of different minerals and / or isotope systems ( with differing closure temperatures ) within the same rock can therefore enable the tracking of the thermal history of the rock in question with time, and thus the history of metamorphic events may become known in detail.
19.
They may be formed from reactions along a single pressure-temperature ( P-T ) loop in a phase diagram, or reactions without changing P-T . For a metamorphic event, monazite is formed by the reactions with more than one P-T loop.
20.
Since the host mineral monazite is quite thermally resistant, these inclusions are protected from age resetting, even at a prolonged exposure at temperature higher than 800 �C, this enables us to restrict an upper limit of the age of the porphyroblasts, and thus the associated metamorphic events.
