The MAGSAT map for Europe shows two significant sign-reversed magnetic anomalies. The negative one is located over Palaeozoic crust, whereas the positive one is over Precambrian crust. As an alternative to a previously published interpretation a three-dimensional model body is presented situated only over Palaeozoic crust showing a magnetization of constant Permian direction but reversed polarity. Varying magnetization intensities are associated with different parts of the body. The predominant remanent magnetization requires a Q ratio clearly above 1. The possible carriers of the magnetization could be pyrrhotite and fine-dispersed magnetite.

The magnetic anomalies in the surroundings of the DEKORP 2-N profile — within a rectangle of 230 km N-S and 170 km E-W — are interpreted by a two-layer model where the shape of an interface between an upper nonmagnetic and a lower magnetized layer can be determined. The depth and the amplitudes of the vertical undulations of the interface may vary within certain intervals.

A deep drilling campaign was performed at Lake Van (Turkey) to enhance the understanding of the paleoenvironmental conditions of the Middle East. Cores were collected, and the sediments are mainly composed of clayey silts and tephra deposits. Spectral gamma ray data were acquired (0–210 m below lake floor), and the uranium data were used for cyclostratigraphic studies to estimate the sedimentation rates and the time of deposition. Detection and analysis of climate cycles require continuous sedimentation and cannot be applied to these sediments which include numerous tephra layers. Therefore, these layers were removed, and a synthetic log was created (cumulative thickness of the tephra ≈50 m; remaining lacustrine sediments ≈160 m). High amplitudes were detected and correlated to Milankovic cycles. Their evolution was analyzed using the sliding window technique. The sedimentation rates varied from 22 to 33 cm/ka in the upper section. The sediments between the lake floor and a depth of 210 m were deposited over a period of 587 ka. Our results agree with core interpretations (e.g., correlation of total organic carbon with marine isotope stages) which suggest a time span of deposition of 600 ka. High-frequency cycles were detected and correlated with interstadials from the North Greenland δ18O record for the past 75 ka. The two datasets agreed closely. We conclude that climate signals, even on sub-Milankovic scale, are imprinted in uranium of these sediments, and cyclostratigraphic methods are applicable if event layers are subtracted from the sediment record.
