Figure 10. Stereographic projections of the EOH directions
(without anomalous ones) for the investigated Hauterivian-Aptian
rock sequences.
1 - and 2 - are the projections of the EOH directions onto the
lower (1) and upper (2) hemispheres; 3 - is the remagnetization
direction by the modern geomagnetic field.
(1-9) distribution of the EOH high-temperature component
vectors: (1) Kremenki and Sengiley sites (Uliyanovsk region);
(2) Forfos Mt. (Members VII to IX) (Syzran district, Samara
region); (3) Chernyi Zaton Village; (4) Fedorov Site (Khvalyn
district, Saratov region); (5) Mark 246 m; (6) Ershov
Site (Khvalyn district, Saratov region); (7) Ust-Kurdyum Village
(Saratov region); (8, 9) combined stereograms for the Barremian-Aptian
rocks of the Khvalyn and Syzran areas (members VII to
XXII): (8) for all deposits, (9A) for clay, (9B) for silt,
siltstone, and fine-grained sand and sandstone; (10-12) distributions
of EOH directions after 100oC (A) and higher-temperature (B) cleanings
in members II to VI (Hauterivian-lower
Barremian): (10) Zakharievskii Mine and Polivna Village
(Uliyanovsk area): members II to VI; (11) Novokashpirskii
Stl. and Forfos Mt. (Syzran area) (members III to VI);
(12) Dubki Stl. (Saratov region) (members V and VI).
