Abstract

LAMPROPHYRIC DIKES FROM THE MILIANÓW 2 BORE HOLE Summary Article presents geological-petrographic characteristic of severa11amprophyre dikes found within carbonate deposits of Devonian (Givetian) age in Milianów 2 bore hole, at depth of 3920 -4128 m. This bore hole is located about 30 km toward ENE from Czętochowa. Petrographic investigations contain macroscopic and microscopic observations, RTG, chemical and thermic differential analysis.
