RESULTS OF A PALEOMAGNETIC RUN-UP OF SANDY LOAMS FROM THE CENTRAL KAMCHATKA DEPRESSION
The so-called “blanket” sandy loams (loess-like volcanogenic deposits) from the Central Kamchatka depression were paleomagnetically studied. From the Kamchatka-river erosion of the Polovinka dene (54°54'40" N, 158°55'40" E), 457 oriented samples were collected. The age of the studied blanket sandy loams, estimated by radiocarbon dating, was 33-55 Ka. A good correlation of D and I parameters was found with the data from the well-known synchronous Kargapolovo section (Siberia) located close to the same latitude and 77° to the west. Such type of correlation of paleosecular variations is well interpreted by the hypothesis of drifting sources of the geomagnetic field, but cannot be described with the central geomagnetic dipole variation. However, the received records of paleosecular variations for the Polovinka section have no geomagnetic excursion similar to the famous synchronous Lashamp-Kargapolovo one, which we expected to find out. A more probable cause is an undetected stratigraphic dislocation in the section.
