Ivanov Forming chemical composition of surface waters in the Arctic. Case study of Lake Inars and the River Paz Questions o f studying the formation o f surface and ground waters, their interaction with rocks, development of the basics o f their rational use and protection are o f great fundamental and practical importance. The influence of the northern Fennoscandian (Baltic) Shield rock composition on forming surface waters' chemical composition in the border area o f Finland - Russia - Norway (Lake Inari, the River Paz) using physical-chemical modeling (Selector software package) has been evaluated. For the physical-chemical modeling there have been made two samples o f chemical analyses o f the most widespread rocks forming the catchment area, with their percentage ratio taken into consideration. Since the catchment area o f the prevailing majority o f streams feeding Lake Inari is composed o f rocks o f the Lapland granulite belt (LGB) and its framing, it will be the main sample (conditional influence o f their composition on the chemical composition o f waters is about 80 %). The second sample includes gneisses, migmatites, granite-gneisses, granites and quartz diorites typical for Inari terrane (conventional influence o f their composition on the chemical composition o f waters is about 20 %). It has been found that the chemical composition o f the surface waters is formed by interaction o f precipitation with intrusive, metamorphic and sedimentary rocks o f northern Fennoskandia containing Clarke concentrations o f S, C, F, Zn, Ni, Pb, Cu. It has been shown that due to interactions in the water - rock system the chemical composition o f Lake Inari waters as well as upper and middle flow o f the River Paz is formed by weathering of granulites o f the Lapland granulite belt and Inari terrane granitoids o f the northern Fennoscandia. The chemical composition o f waters in the River Paz downstream is formed by weathering o f metamorphosed volcanic and sedimentary rocks o f the Pechenga structure and the impact o f industrial pollution.
