Abstract

Field survey of weathering sites in the Wyborg rapakivi area indicates that saprolites are far more common in the central part of the massif than in the marginal areas. Many till-covered saprolites and parautochthonous crust-tills prove the weathering to be of preglacial origin. The rapakivi saprolites are of grus type. The weathering has caused both mechanical and chemical alteration of the parent rock. The residual topography comprises small tor-like features
