The maximum thickness of the Suisari Formation (SF) of the Onega Basin that is confined to the Ukshozero synform structure is more than 600 m. The SF successions of the Konchozero–Yalguba Ridge area have a thickness of about 340 m and mainly comprise lavas (up to 75%). The SF is subdivided into 5 subsections:
SF1 (thick 15–130 m) The lower unit of the SF1 at the border with ZF is composed of basaltic and picrobasaltic tuffs, tuffites, and tuff-conglomerates. The middle unit of SF1 comprises basaltic massive and pillow lavas (with lava flow thickness 3–15 m), interbedded with agglomerate, silty-lithic and psammitic tuffs. The upper unit is represented by a series of variolitic lavas with a thickness of 5–25 m.
SF2 (thick 0–90 m) is formed by tuffs, tuffites with cross and parallel bedding, interbedded with picrobasaltic massive lava flows.
SF3 (thick 5–140 m) is represented by lava flows (1.5 to 18 m thick) of massive and brecciated Pl-Cpx phyric basalts, interbedded with tuffs and tuffites.
SF4 (thick 20–200 m) lavas of massive augite basalts interbedded with crystal-clastic tuffs.
SF5 (thick 0–40 m) is formed by a series of basaltic pillow lava flows with agglomeratic tuffs.
