Book excerpt: Twenty-two hundred kilometers of Alaskan coastline, from Sanak to Baranof Islands, contains evidence of a Cretaceous to Eocene trench-ridge-trench (TRT) triple junction. Due to the long-term presence of inboard right-lateral strike-slip faults, the original location of the TRT triple junction with respect to North America is unknown. Previous paleomagnetic studies of the Ghost Rocks Formation of the Kodiak Islands, AK indicate a Latest Cretaceous to Early Paleocene TRT triple junction location of ~42 degrees north latitude (Plumley et al., 1983). However, this data set has proved controversial in the literature due to discordant site mean directions between the two major bays studied (Alitak and Kiliuda) as well as a 2-stage structural correction in Alitak Bay and possible remagnitization (e.g. Haeussler et al., (2003a). This study presents new sedimentologic, structural geologic, and preliminary paleomagnetic data in an attempt to resolve the location of TRT the triple junction. The Ghost Rocks Formation is part of an accretionary complex which contains turbidites interlayered with pillow lavas and intruded by gabbro and mafic sills. New structural geologic mapping of the Ghost Rocks Formation shows a mean bedding strike of ~250 degrees, and small-scale block rotations in Alitak Bay. Oriented samples across the formation were taken to include a baked contact test, conglomerate test, and fold test to ensure reliable data. 14 sites from Alitak Bay have been fully analyzed, and 12 sites have been partially analyzed. Second-removed magnetic components represent primary magnetization, and 13 sites showed reliable demagnetization behavior and bedding measurements. In-situ site mean direction for these 13 sites (D=349, I=-45, n=13, k=4.3, [alpha]95=22.8) is improved when corrected for local stratigraphy and structural block rotations (D=178, I=-63, n=13, k=29.2, [alpha]95=7.8). These results are in partial agreement with the original data, and show an improved agreement between the original Kiliuda Bay and the new Alitak Bay declination directions. Continued study of remaining sites will further constrain the data.

Available in PDF, EPUB and Kindle. Book excerpt: Ichnology is the study of traces created in the substrate by living organisms. This is the first book to systematically cover basic concepts and applications in both paleobiology and sedimentology, bridging the gap between the two main facets of the field. It emphasizes the importance of understanding ecologic controls on benthic fauna distribution and the role of burrowing organisms in changing their environments. A detailed analysis of the ichnology of a range of depositional environments is presented using examples from the Precambrian to the recent, and the use of trace fossils in facies analysis and sequence stratigraphy is discussed. The potential for biogenic structures to provide valuable information and solve problems in a wide range of fields is also highlighted. An invaluable resource for researchers and graduate students in paleontology, sedimentology and sequence stratigraphy, this book will also be of interest to industry professionals working in petroleum geoscience.

This book was released on 2016 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analysis of sedimentary lithologies and structures in selected outcrop sites at Slope Mountain, Alaska identified thirteen distinct facies within a subsample of the Cretaceous (Albian-Cenomanian) Nanushuk Formation. Based on the distribution of the thirteen facies, this study defines five unique facies associations at Slope Mountain, each representing a specific depositional environment. The facies associations are as follows: 1) distributary channel bar, 2) tidal channel, 3) upper shoreface, 4) distributary mouth bar, and 5) fluvial channel. The relative stratigraphic positions of the facies associations in outcrop have implications for fluctuations in shifting shoreline positions within the Nanushuk Formation over time. The progression of facies associations within several hundred meters of section analyzed in this study depict a shift from a regressive deltaic system (sedimentation>accommodation) to an alluvial system affected by local transgression (sedimentationaccommodation). Despite significant overall accommodation in the Colville basin, the dominant pattern of Nanushuk Formation sedimentation is highly regressive, with significant progradation and aggradation of deltaic and alluvial deposits throughout the Albian-Cenomanian.
