S. Y. Mullari Small forest lakes are a typical element o f landscape in Pasvik. Pasvik's relief is hilly with average heights o f ca. 50 m and m axim um heights up to 400—500 m. The relief significantly changes from the source to the mouth o f Pasvik. The source near Lake Inari is a swampy plain with well developed drainage located 100—150 m a.s.l. In the m iddle flow o f the river isolated hills are located, their height increasing towards the north from 250 up to 400 m and more. The lower flow o f Pasvik is surrounded by denudation plain with isolated hills. The hills have flat tops, steep slopes and are 400—500 m high above sea level. Stony alluvial deposits, slide rocks and rock outcrops are typical o f this area. The coastal part o f the valley drops to the sea by a bench 100—150 m high. The rifts that cross the plain form fjords stretching mainly towards the northeast and north. The Pasvik valley and the adjacent area is part o f the Baltic shield o f the Russian platform . Strongly m etam orphised A rchaean and P roterozoic rocks, i.e. granite and gneiss are abundant here. They crop out on m oun tain tops. In depres­ sions the parent material is capped by m arine, glacial and outwash overburden (Apukhtin 1958, 1967, Lavrova 1960). Currently different eluvial and deluvial deposits are being formed there. From the viewpoint o f tectonics, A rchaean folded structures modified by Karelian rugosity and pre-K arelian granitoids in modified massifs dom inate in Pasvik. Karelids have a m ulti-strata structure. They are intersected by the zones o f abyssal fracture w ith intrusions o f different age. N um erous rup tu res o f the crys- talised basis divide it into smaller blocks that are still in m otion. 14
