摘要:

The Breven dolerite dike in the eastern part of south central Sweden has been remapped. A large central part of the dike is occupied by a red granophyre, most probably a late differentiate of the dolerite. To the east of the major dike there is a hybrid dolerite-breccia with xenoliths of granophyre showing different stages of assimilation. The latter dike has a width of around 100 m and a length of at least 8 km. These observations suggest several pulses of dolerite in the dike system.
