MARC recordHydrothermal alteration in some volcano-sedimentary associations in Central Finnish Lapland / Pasi Eilu.
| Title: | Hydrothermal alteration in some volcano-sedimentary associations in Central Finnish Lapland / Pasi Eilu. |
| Author(s): | Eilu, Pasi. |
| Date: | 1993. |
| In: | Geological Survey of Finland. Special Paper. (1993.), Vol. 18 (1993) |
| Abstract: | Volcanic sequence of Central Lapland greenstones has locally undergone multi-stage synvolcanic hydrothermal alteration followed by regional metamorphic recrystallisation and replacement. Main hydrothermal event had three alteration phases: chloritisation, albitisation and carbonation. Later sericitisation ± chloritisation event was less pervasive. Talc was formed before regional metamorphism. Only evidence of post-metamorphic events at study sites today is tiny carbonate and haematite-filled fractures. |
