LOCAL FORMATION OF HERCYNITE-PLAGIOCLASE SYMPLECTITE AFTER GARNET AND SILLIMANITE IN KHONDALITE FROM HABARANA, SRI LANKA : MINERAL TEXTURES
スポンサーリンク
概要
- 論文の詳細を見る
Khondalite (graphitic garnet-sillimanite-alkali feldspar-quartz granulite) is one of the characteristic rocks of the granulite facies Highland Series in Sri Lanka. Near Habarana occurs unusual khondalite in which both sillimanite and garnet are locally replaced by symplectitic intergrowths of hercynite and plagioclase to various degrees. Mineral textures suggest that the replacement reactions took place along pathways of fluid phase, most likely CO_2-rich fluid, which infiltrated from outside, and were triggered off by the breakdown of apatite with resultant formation of monazite.
