As shown in Fig. 1, the contour of the Zavitinskii pegmatitic area corresponds to a sublatitu-dinally oriented local gravity minimum (25 × 16 km in plan view) that reflects concentrated Mesozoic granite WebMost of the Ordovician and Devonian granitic bodies in the Lake District have been quarried to some extent.
