1. Andalusite forms during the regional metamorphism of shale.

2. Regional metamorphism produced parageneses of the almandine amphibolite facies.

3. Almandine originated from regional metamorphism to which magmatic thermal metamorphism superimposed.

4. 22 Through late regional metamorphism, the phosphorite was turned into the apatite deposit.

5. General characteristics for distinguishing apogranite greisens affected by regional metamorphism from metapelitic mica schists are given.

6. 13 The middle Proterozoic crystalline schist series in the Panzhihua - Xichang region has undergone progressive regional metamorphism.

7. Precambrian amphibolites and quartz-mica schists in the Saidapuram-Podalakuru area fall within the almandine-amphibolite facies of regional metamorphism.

8. The crystals occur in the disequilibrium assemblage calcite – phengite (2M1) – margarite – quartz – kaolinite – epidote –apatite found in Badshot marble from the almandine garnet zone of regional metamorphism.

9. Slightly foliated, Amphibolites generally form during the regional metamorphism of igneous rocks primarily composed of ferromagnesian minerals, though other types of the rocks are also known to occur.

10. 1.12) formed under regional metamorphism or at contact metamorphic zone around intrusive igneous rocks.Andalusite is a rock-forming industrial mineral and belongs to Andalusite, kyanite, and sillimanite group, important for the geothermometry and geobarometry of metamorphic rocks.

11. The occurrence ofMiyashiro's andalusite-sillimanite type and low-pressure intermediate group of regional metamorphism in orogenic belts of widely different age merely signifies that in all these belts granitic magma that was formed in depth, rose to higher levels.

12. metamorphites, Mesozoic igneous intrusive rocks, Tertiary volcanic and sedimentary breccias, and Quaternary alluvia. The Precambrian Halloran Complex has been subdivided into the following formations: (1) Silver Lake Peak Formation, mostly quartzofeldspathic gneisses; (2) Cree Camp Formation, quartzites and metarhyolites; (3) Riggs Formation, metamorphosed carbonate rocks. This complex is intruded by dioritic rocks. Regional metamorphism produced parageneses of the almandine amphibolite facies. Metablastesis was a major phenomenon, partial fusion was a local one. The rocks are, therefore, metatexites. Regional metamorphism was followed by diaphthoresis, accentuated in a zone of dislocation.

13. Moreover, according toMiyashiro regional metamorphism of his kyanite-sillimanite type (= Dalradian or Barrovian type) was common in Palaeozoic time, whereas that of his andalusite-sillimanite type and low-pressure intermediate group (Buchan type) took place in orogenic belts of Precambrian as well as Palaeozoic and Mesozoic age.

14. Two grades of metamorphism, both subfacies of the greenschist facies of regional metamorphism, were mapped on the Araya Peninsula: 1. the quartzalbite-epidote-almandine subfacies, consisting mainly of a sequence of garnet and kyanite quartz-mica schists, interlayered with quartzites; and 2. the quartzalbite-muscovite-chlorite subfacies, which consists of chloritic phyllites, quartzmica schists and phyllites, metaconglomerates, calcareous quartz-mica schists, limestones and marbles, and calcareous epidote schists of volcanic origin.
