Magnetostratigraphic and micropaleontological data from the Campanian–Mastrichtian section near Levashi Village (Dagestan)

Preserved oriented samples from the reference Campanian–Maastrichtian section near Levashi village (Dagestan), sampled in 1990 by the staff of the SSU Research Institute of Geology, were studied in terms of rock magnetism and paleomagnetism. Benthic foraminiferal assemblages and calcareous microproblematica (gilianelles) were identified in selected samples, and layers with fauna were distinguished. Thin sections were made from a number of samples for microscopic examination of rocks.

First Magnetostratigraphic Data on the Maastrihtian of Mountain Crimea (Bakhchysarai Region)

The representative data about magnetic susceptibility, its anisotropy before and after heating up to 500°C and other petromagnetic characteristics were received on two sections of carbonate sediments of Maastrihtian – Chahmahly and Takma, located in Bakhchysarai region of the Republic of Crimea. In the studied sections there were established the magnetozones of normal and anomalous polarity, the comparison of determined zones with Geomagnetic Polarity Time Scale was conducted.
