| Abstract: | |
| General descriptions of the different metasedimentary, metavolcanic and igneous rocks occurring within the area of the two map-sheets are presented. Three principal map-subdivisions are recognized: (a) a Precambrian (supposed Karelian) supracrustal sequence occurring in a tectonic window; (b) autochthonous Late Precambrian to Lower Cambrian metasediments; (c) an allochthonous (Caledonian) complex of Precambrian and Eocambrian metasediments, gneisses and igneous rocks. The major geological subdivisions of the map-area are outlined. In the final chapters, some information is presented on the economic geology, including the important flagstone industry, and geophysical and geochemical investigations. An excursion guide to localities of the most characteristic rock-types is also included. |
