| Tartalmi kivonat: | A characteristic feature of the NE part of the Tisia is the occurence of high pressure relics in the Variscan metabasic rocks. A new eclogite sample, brought to the surface by the Szarvas-16 borehole contains garnet, clinozoisite. kyanite, rutile and phengite as HP relict grains in a symplectitic material. As the most significant secondary phase, amphibole occurs. Chemical composition and zoning tendencies of these minerals as well as the PT path modelled by different prograde and retrograde parageneses result in a two stage metamorphic evolution. In good agreement with earlier data, the B-type eclogite sample broke down under greenschist facies condition and recrystallized in the amphibolite facies afterwards. |
