Description
Summary:in area, is located in the southeastern Baltic Shield. The massif is divided by submeridional faults into three (northeastern Agan-ozero, central Shalozero, and southeastern Burakov) blocks. The massif is overlain by a thick cover of Qua-ternary sediments. The reconstruction of its vertical structure became possible only due to prospecting and mapping drilling carried out by the Karelian Geological Expedition from 1984 [1, 2], and the massif could be assigned to potentially platiniferous ones [3]. The weighted average composition of the intrusive one is close to that of komatiites [2]. The vertical section of the intrusive one is subdi-vided into the upper and lower near-contact zones (UCZ and LCZ) and the layered series (LS) with five alternating zones distinguished by prevailing cumula-tive parageneses [2]. The geochemical characteristics of the general vertical section is based on analytical data obtained for rocks from the following zones (from bottom to top): LCZ (Hole 20); ultramafic zone, UZ;
