Figure 8. Structural elements of the Blyava synform:
1 - soft Cenozoic sediments; 2 - polymictic olistostromes; 3 - ophiolitoclastic
mixtites; 4 - siliciclastic olistostromes; 5 - siliceous sediments
(D1-2);
6 - basalts with chert and siliciclastic rock lenses - Ishmuratovo Formation (D1-2);
7 - siliceous black-shale Sakmara Formation (S1-2); 8 - tuffaceous sediments of
the upper part of the Kuragan Formation (Guberlya Formation analogs O2-3);
9 - tuffaceous sediments and basalts of the lower part of the Kuragan Formation (O1-2);
10-12 - extrusive complex of mixed composition (Baulus (O3) and Blyava (S1) formations):
10 - nonsubdivided basaltoids of the Blyava and upper Baulus formations, 11 - acidic extrusions
of the upper Baulus Formation, 12 - acidic and basic extrusions of the lower Baulus Formation;
13 - arkosic sandstones and siltstones of the Kidryasovo Series (O1t); 14 - diorites
(O3);
15 - massive sulfide ores; 16 - nappe boundaries; 17 - other faults; 18 - points of conodont
localities, their numbers and age. Figures indicate massive sulfide ore deposits: 1 - Blyava,
2 - Komsomol'skoe, 3 - Yamankasy, 4 - Razumovskoe.
