The problems concerned wi1l be particu1arly the formation of the Proterozoic 1i thosphere, the co~tinua tion of ArcheanlTEhoge·I}e'El.c processes- in - ~- Proterozoic, and the~ve~opment~I:the-Soundary 1fetween tne PioteroZOlcärid the Archean in the central Baltic :.s1iie ld, i. e. tne-S-vecokarel lan-··-an-cf Archean- -reg ions- ef Finiand and Sweden. In addition, these aspects wi1l be related to the general Proterozoic development of the shie1d. Since this is the first effort at such a co-operation attempting to knit together more c1ose1y the treatment of Ear1y and Mid Proterozoic prob1ems in Finland, Sweden and Norway, it is our idea to limit participation in this pioneer workshop to a number of invited workers who are personal1y invo1ved in research on the subject, encouraging them to give reviewsof their particu1ar fields of work. We wou1d also 1ike to keep the workshop as informal as possib1e, not, at this stage, involving governmenta1 organizations as such. ) To get things gOing, we suggest that we meet already on March ) 4-6th, 1985 in Helsinki. Housing at reduced prices in shared double rooms wil1 be arranged in Helsinki and we have good hopes of being ab1e to raise funds to subsidize travel1ing particularly for participants from continental Europe and Britain. Please indicate your interest to participate on the enclosed form and return it before September 1, 1984 to R.
