Sediment cores retrieved from 6 locations in Lake Baikal were subjected to a paleomagnetic study in order to establish detailed age models based on correlations of relative paleointensity records. Additional data were provided by calibrated accelerator mass spectrometry (AMS) 14 C dating, as well as by documentation of geomagnetic excursions like Laschamp at ~ 42 ka and Iceland Basin at ~ 185 ka. Few intervals were affected by diagenetic features like selective reductive dissolution of magnetite and greigite mineralization (Demory et al., this issue), and those that were, were left out of paleointensity records. These records were tuned to the well-dated paleomagnetic record from ODP Site 984 (Channell, 1999). The complex shape of the resulting depth/age curves highlights the need for a high resolution age model.

“…Previous studies of depositional AMS in sediments have shown that the shape and orientation of the magnetic fabric can be related to different sedimentological processes during the deposition of particles from suspension in water (Ellwood, 1980;Rees, 1965;Rees et al, 1968;Rees & Woodall, 1975;Weiler, 2007). The initial sedimentary fabrics are generally determined by gravity and currents.…”

“…The credibility of the AMS fabric as a paleocurrent and depositional indicator is known from work on natural (Ellwood and Ledbetter, 1979;Abdeldayem et al, 1999;Liu et al, 2001) and laboratory deposited sediments (Rees, 1965;Rees and Woodall, 1975). Furthermore, AMS has been used to evaluate flow vectors in lava flows (Cañón-Tapia et al, 1996Cañón-Tapia and Walker, 1998;MacDonald et al, 1992) and pyroclastic deposits (e.g., Ellwood, 1982;Incoronato et al, 1983;Knight et al, 1986;Wolff et al, 1989;MacDonald and Palmer, 1990;Hillhouse and Wells, 1991;Seaman et al, 1991;Ort, 1993;Cagnoli and Tarling, 1997;MacDonald et al, 1998;Ort et al, 1999), in order to determine vent locations, or transport and depositional processes at different distances from the vent (e.g., Fisher et al, 1993;Baer et al, 1997;Le Pennec et al, 1998;Palmer and MacDonald, 1999).…”

“…The initial fabrics are largely determined by gravitational and hydrodynamic forces and, hence, are mainly controlled by the size, shape and mass of detrital grains and velocity of the medium in which they are being transported (Tarling and Hrouda, 1993). In these sediments, the current would usually be parallel to the K 1 axis; in favorable conditions its absolute direction may be inferred from the tilting direction of the K 3 axis (Rees, 1965;Tarling and Hrouda, 1993;Tarling and Shi, 1995;Piper et al, 1996;Abdelayem et al, 1999). However, the current could be perpendicular to K 1 if the flow is strong enough and the grains are fine (Ellwood and Ledbetter, 1977).…”

Sources of ancient volcanic rocks are often unknown if they are either eroded and/or covered by younger deposits. This problem, as well as the provenance of reworked volcaniclastic, fluvial and mass-flow deposits, can be partially solved by the application of anisotropy of the magnetic susceptibility (AMS). For massive and poorly sorted volcaniclastic rocks in particular this may be the only way of finding reliable transport directions and therefore allowing for paleogeographic reconstructions. Here, we present a data set of 428 AMS measurements and 249 measurements of sedimentary paleocurrent indicators from the Miocene Tepoztlán Formation at the southern edge of the Transmexican Volcanic Belt (Central Mexico). The highest degree of reliability of AMS measurements is gained for data from lava samples and the lowest from mass flows. Sedimentary structures in sandstones and conglomerates such as trough cross-stratification, asymmetric ripple marks, and the shape of scours and channels could be used to calibrate the results from AMS data and to prove their reliability. AMS data on fluvial deposits point to a drainage system with a W-E flow direction, indicating an outflow of the river system into the ancient Gulf of Mexico.Keywords: Anisotropy of magnetic susceptibility; paleocurrent direction; volcaniclastic; Transmexican Volcanic Belt; Miocene; Mexico 3 In ancient volcanic settings, one challenge in the investigation of volcanic and volcaniclastic deposits is the determination of source vent locations, since former volcanic centers may be either eroded and/or covered by younger deposits. Furthermore, the determination of the provenance of fluvial and mass-flow deposits, arising from the volcanic ring plain itself (Manville et al., 2009, and references therein) or rivers in distal reaches, can also be problematic. In lava flows, both vesicle and crystal preferred orientations have been used extensively for this purpose (e.g., Waters, 1960;Smith and Rhodes, 1972;Walker, 1989;Cashman and Kauahikaua, 1997;Manga, 1998;Iezzi and Ventura, 2002). However, petrological structures such as foliation and lineation due to the movement of a lava flow are often difficult to observe and measure (Bascou et al., 2005). Massive pyroclastic rocks such as ignimbrites and block-and-ash flow deposits rarely show any measurable alignment or structure that can help determine flow direction. However, the magnetic fabric can be used to determine their paleocurrent direction, and the speed, precision, cheapness and range of applicability make it unique in this regard (Tarling and Hrouda, 1993).All materials, even if they do not acquire remanent magnetization, have a magnetic susceptibility (Liu et al., 2001), which is not always isotropic in the rock (Ising, 1942). This spatial susceptibility variation is defined as the anisotropy of magnetic susceptibility (AMS) and reflects the preferred orientation of magnetic minerals in the rock or sediments, i.e. its magnetic fabric (Hrouda, 1982;Tarling and Hrouda, 1993), which yields thr...
