    Shelf-edge trajectories and stratal stacking patterns: Their sequence-stratigraphic significance and relation to styles of deep-water sedimentation and amount of deep-water sandstone (2015)
    American Association of Petroleum Geologists (AAPG)
    Details
    Publication Date: 2015-07-07
    Description: Using a seismic database from the Qiongdongnan Basin in the South China Sea, this study demonstrates that shelf-edge trajectories and stratal stacking patterns are reliable, but understated, predictors of deep-water sedimentation styles and volumes of deep-water sand deposits, assisting greatly in locating sand-rich environments and in developing a more predictive and dynamic stratigraphy. Three main types of shelf-edge trajectories and their associated stratal stacking patterns were recognized: (1) flat to slightly falling trajectories with negative trajectory angles ( $${T}_{\mathrm{se}}$$ ) (–2° to 0°) and negative shelf-edge aggradation to progradation ratios ( $$\mathrm{d}y/\mathrm{d}x$$ ) (–0.04 to 0) and associated progradational and downstepping stacking patterns with low clinoform relief ( $${R}_{\mathrm{c}}$$ ) (150–550 m [492–1804 ft]) and negative differential sedimentation on the shelf and basin ( $${A}_{\mathrm{s}}/{A}_{\mathrm{b}}$$ ) (–0.6 to 0); (2) slightly rising trajectories with moderate $${T}_{\mathrm{se}}$$ (0°–2°) and medium $$\mathrm{d}y/\mathrm{d}x$$ (0–0.04), and associated progradational and aggradational stacking patterns with intermediate $${R}_{\mathrm{c}}$$ (250–400 m [820–1312 ft]) and intermediate $${A}_{\mathrm{s}}/{A}_{\mathrm{b}}$$ (0–0.6); and (3) steeply rising trajectories with high $${T}_{\mathrm{se}}$$ (2°–6°) and high $$\mathrm{d}y/\mathrm{d}x$$ (0.04–0.10) and associated dominantly aggradational stacking patterns with high $${R}_{\mathrm{c}}$$ (350–650 m [1148–2132 ft]) and high $${A}_{\mathrm{s}}/{A}_{\mathrm{b}}$$ (1–2). Each trajectory regime represents a specific stratal stacking patterns, providing new tools to define a model-independent methodology for sequence stratigraphy. Flat to slightly falling shelf-edge trajectories and progradational and downstepping stacking patterns are empirically related to large-scale, sand-rich gravity flows and associated bigger and thicker sand-rich submarine fan systems. Slightly rising shelf-edge trajectories and progradational and aggradational stacking patterns are associated with mixed sand/mud gravity flows and moderate-scale slope-sand deposits. Steeply rising shelf-edge trajectories and dominantly aggradational stacking patterns are fronted by large-scale mass-wasting processes and associated areally extensive mass-transport systems. Therefore, given a constant sediment supply, then $${T}_{\mathrm{se}}$$ , $$\mathrm{d}y/\mathrm{d}x$$ , $${R}_{\mathrm{c}}$$ , and $${A}_{\mathrm{s}}/{A}_{\mathrm{b}}$$ are all proportional to intensity of mass-wasting processes and to amounts of mass-transport deposits, and are inversely proportional to the intensity of sand-rich gravity flows and to amounts of deep-water sandstone. These relationships can be employed to relate quantitative characteristics of shelf-edge trajectories and stratal stacking patterns to deep-water sedimentation styles.

    AMPK is a direct adenylate charge-regulated protein kinase (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-06-18
    Description: The adenosine monophosphate (AMP)-activated protein kinase (AMPK) regulates whole-body and cellular energy balance in response to energy demand and supply. AMPK is an alphabetagamma heterotrimer activated by decreasing concentrations of adenosine triphosphate (ATP) and increasing AMP concentrations. AMPK activation depends on phosphorylation of the alpha catalytic subunit on threonine-172 (Thr(172)) by kinases LKB1 or CaMKKbeta, and this is promoted by AMP binding to the gamma subunit. AMP sustains activity by inhibiting dephosphorylation of alpha-Thr(172), whereas ATP promotes dephosphorylation. Adenosine diphosphate (ADP), like AMP, bound to gamma sites 1 and 3 and stimulated alpha-Thr(172) phosphorylation. However, in contrast to AMP, ADP did not directly activate phosphorylated AMPK. In this way, both ADP/ATP and AMP/ATP ratios contribute to AMPK regulation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Oakhill, Jonathan S -- Steel, Rohan -- Chen, Zhi-Ping -- Scott, John W -- Ling, Naomi -- Tam, Shanna -- Kemp, Bruce E -- New York, N.Y. -- Science. 2011 Jun 17;332(6036):1433-5. doi: 10.1126/science.1200094.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Protein Chemistry and Metabolism, St. Vincent's Institute of Medical Research, University of Melbourne, 41 Victoria Parade, Fitzroy 3065, Victoria, Australia. joakhill@svi.edu.au〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21680840" target="_blank"〉PubMed〈/a〉

    Notes: SUMMARY— The free amino acids and total ninhydrin positive material (NPM) in a 1% picric acid extract from dry-cured hams were measured after six different periods of aging. Correlation coefficients were calculated between amino acid values and taste panel scores. Significant (P 〈 .051 increases were observed for NPM, serine, glutamic acid, threonine, leucine and isoleucine (not separated), valine, phenylalanine, proline, tyrosine, alanine, glycine and histidine during successive aging periods. Correlation coefficients between NPM and the organoleptic measurements of aged flavor, acidity, elasticity, crumbliness and softness were all highly significant. It k postulated that the increase in free amino acids can be attributed to action of the naturally occurring cathepsins. The free amino acids and their changes in concentration in relationship to flavor are discussed.

    Notes: Coastal cliff exposures in the Helvetiafjellet Fm. deltaic succession near Kvalvågen on eastern Spitsbergen show spectacular evidence of syndepositional, gravity-driven deformation and resedimentation associated with delta-front instability, most probably triggered by earthquakes. This short article summarizes the results of a recent study of these features, with emphasis on the actual sequence of processes recorded in the outcrop. Detailed analysis of the structural style of the delta-front collapse and the associated sedimentation processes is presented elsewhere (Nemec et al. 1988).

    The sedimentary history of a debris-flow dominated, Devonian alluvial fan–a study of textural inversion (1978)

    Notes: Karlskaret fan, with a radius of less than 11/2 km and dominated by debris-flow conglomerates, is one of numerous alluvial fans built out from the fault margins of Hornelen Basin (Devonian, Norway). The fan body is more than 170 m thick proximally, consists of four main coarsening-upwards segments and thins distally by a rising of its base and by a vigorous interfingering with very fine-grained sediments originating from an adjacent, impinging floodbasin system.Within the entire fan body, and within individual lobes, is a proximal-distal (and vertical) facies change from sheet-like, polymodal debris-flow conglomerates through matrix-rich conglomerates that are commonly distorted by loading, slumping and faulting, to remarkably sheet-like, matrix-rich granule sandstone of subaqueous debris-flow origin.Because the alluvial fan prograded into an actively aggrading floodbasin the primary fanglomerates, themselves having been subject to some sorting on the fan surface, incorporated large quantitites of very fine sediments. This inclusion of fines, effectively a textural inversion on the lower fan reaches, frequently led to remobilization and resedimentation of material beyond the fan toe. Anomalous maximum particle size/bed thickness relationships and a variety of graded textures within these resedimented beds suggest deposition in lacustrine areas of the adjacent floodbasin.

    Structures and textures in Triassic braided stream conglomerates (‘Bunter’ Pebble Beds) in the Sherwood Sandstone Group, North Staffordshire, England (1983)
    Oxford, UK : Blackwell Publishing Ltd
    Sedimentology 30 (1983), S. 0

    Notes: In the northern parts of the Needwood and Stafford/Eccleshall Basins, England, the Pebble Beds of the Sherwood Sandstone Group contain thick successions of texturally mature, fluvial pebble/cobble conglomerates which are organized into either horizontal or cross-stratified sets. The horizontally lying sets, generally coarser grained and more poorly sorted than the cross-bedded sets, are usually disorganized and either matrix- or clast-supported, although thin lenses of well-sorted, occasionally openwork units, interpreted as falling stage phenomena, are often present. The cross-stratified conglomerates have foresets exhibiting remarkable textural organization, with a coarse, bimodal (sometimes matrix-supported) part grading upwards or being abruptly overlain by a finer, well-sorted (occasionally openwork) part and finally capped by sandstone. These rhythmic textural changes are attributed partly to an avalanche process at high stage and partly to falling stage conditions. The most common types of vertical association are thick successions of horizontally bedded conglomerates (up to 20 m) and sequences of an upwards coarsening nature (2-12 m) in which cross-stratified sets are overlain by flat-lying sets.The environment of deposition of the gravels is interpreted as one in which water depths at high stage were greater than depths in most modern braided stream plains (proglacial or alluvial fan) but shallower than depths associated with the Pleistocene catastrophic floods from which texturally mature, giant gravel bars have been recorded. Recent braided streams with relatively confined channels and considerable bar/channel relief are better analogues. In particular, medial or mid-channel bars with a two-tier structure (subaqueous and partly emergent portions) may explain the upward-coarsening sequences in which horizontally lying conglomerates overlie cross-stratified conglomerates. The thicker sequences of horizontally stratified conglomerates represent proximal, longitudinal bar deposits.Sheets of pebbly sandstone and argillaceous sandstone lying between the conglomerates, and commonly occurring towards the top of the succession, largely represent deposition from sandwaves and dunes. Finer, interbedded, argillaceous sandstones, siltstones and mudstones are interpreted as overbank and waning-flood deposits.Basin-forming tectonism of increasing intensity probably caused the initial coarsening upwards of the lower part of the succession, whilst more stable tectonic conditions and decreasing relief on the margins of the basins and in the areas of provenance in the Midlands and the Hercynides, account for the upwards-fining of the upper part of the succession.
