    A revised estimation of the steady-state geotherm for the continental lithosphere and its implication for mantle melting (1996)

    Notes: An analytical solution has been derived for the steady-state geotherm of the continental lithosphere, using an empirical thermal conductivity model that incorporates the experimentally observed temperature and pressure effect. Based on recent global compilations of crustal thickness and heat flow data, a standard continental lithosphere is re-defined by a global mean model with total crustal thickness of 40 km and surface heat flow of 55 mWm-2 (within which 28 mWm-2 is assumed to be derived from deep mantle source). The thickness of the continental lithosphere (≅125 km), consistent with previous models, is given by the depth at which the geotherm intersects the potential asthenosphere temperature of 1280°C. It is shown that the new steady-state geotherm is much hotter than that based on the previously adopted model where material thermal conductivity is assumed to be constant (≅3.14 W/m/k) throughout the lithosphere. The consequence of this re-evaluation of pre-extension thermal structure in the lithosphere is that the minimum stretching factor required to cause the onset of dry mantle partial melting can be 15–20% lower than the previous estimate. Also, if minor amounts of water or other volatile element or dry basalt are present in the upper mantle, melting of the subcontirfental mantle is very likely to occur for any geotherms constructed using surface heat flows 〉 30 mWm-2.

    A 3-D Backstripping Method and Its Application to the Eromanga Basin In Central and Eastern Australia (1993)

    Notes: A general 3-D backstripping method, based on a precise model of plate deformation, is developed for analysis of the tectonic history of sedimentary basins, and it has been applied to the Eromanga Basin in central and eastern Australia. the 3-D method is more appropriate when dealing with the subsidence history of basins, since it takes into account both the flexural effect of surface load and the stress relaxation in the lithosphere due to viscous creep of mantle material. Furthermore, this method is more accurate than conventional thin plate models. It is shown that the 3-D model provides a different, yet simple and clear evolving picture of the areal extent of the tectonic subsidence of basins.The 3-D analysis results show that the formation of the Eromanga Basin is characterized by a gradual increase in the extent of sedimentation with localized subsidence from the Late Triassic to the Early Cretaceous and a large extension of sedimentation with rapid subsidence during the Early to Middle Cretaceous, followed by local and gradual subsidence after the Middle Cretaceous.

    A model of thick plate deformation and its application to the isostatic movements due to surface, subsurface and internal loadings (1991)
    Oxford, UK : Blackwell Publishing Ltd
    Geophysical journal international 105 (1991), S. 0 
    Details
    ISSN: 1365-246X
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Geosciences
    Notes: A model of thick plate deformation is presented without any restriction on stress or strain conditions in the plate. An analytical solution is given for the vertical displacement of a thick elastic plate. The present method is exact and applicable to 3-D plate deformation problems associated with surface, subsurface and internal loadings.The conventional thin plate theory, which ignores the variation of vertical strain of a plate, may not be appropriate to be used as a basic model to study deformation problems of the continental lithosphere, since it is shown that the actual surface isostatic adjustment due to surface loading could reach an amount twice as much as predicted by thin plate theory, even on a relatively thin plate with 30 km thickness and Young's modulus E= 1000 kbar and Poisson's ratio v= 0.25.The isostatic adjustment due to surface load depends on the stress condition at the lower boundary of the elastic lithosphere. If there is an active mantle upwelling or downwelling force acting on the boundary, then the isostatic adjustment, depending on the magnitude of the mantle force, is either greatly hindered or amplified to a degree that is beyond the normal prediction of isostatic movements. In addition, the viscous effect of mantle material on the isostatic movements is shown to be negligible on geological time-scales if the mantle viscosity is below 1024 poise. It is also shown that the Airy isostasy of the total sediment load in a surface depression with small wavelength could be achieved only if a considerable period of geological time is allowed for the stress relaxation of viscoelastic or viscous material in the lithosphere. The rheological property of the continental lithosphere has a significant effect on basin subsidence caused by sediment loading alone, while pure elastic lithosphere restricts surface basin development because of the strong basement support throughout the evolution history.

    Power Spectra Analysis of Aeromagnetic Data and KTB Susceptibility Logs, and their Implication for Fractal Behavior of Crustal Magnetization (1998)

    Notes: Abstract. —Power spectra analysis of aeromagnetic data from the southeast North Sea, where the depth to the top of the magnetic sources is reasonably well constrained, indicates that the scaling factor or spectral exponent (β) in an area with thick sediment cover is likely to be significantly different from the expected value of -3. This is consistent with the results from analyzing the KTB susceptibility data, which show that the magnetic scaling factor changes with burial depth. For sources shallower than about 1 km, a β value of -2.3 is roughly consistent with previous similar investigations. For sources deeper than a few kilometers, the β value could be as low as -1.0. Therefore, the depth estimation using power spectra analysis of magnetic data should be treated with caution, especially if there is no independent constraint on the source depth or the scaling factor (for instance from susceptibility logs in boreholes).

    Description: Sensors, Vol. 17, Pages 2055: Railway Tunnel Clearance Inspection Method Based on 3D Point Cloud from Mobile Laser Scanning Sensors doi: 10.3390/s17092055 Authors: Yuhui Zhou Shaohua Wang Xi Mei Wangling Yin Chunfeng Lin Qingwu Hu Qingzhou Mao Railway tunnel clearance is directly related to the safe operation of trains and upgrading of freight capacity. As more and more railway are put into operation and the operation is continuously becoming faster, the railway tunnel clearance inspection should be more precise and efficient. In view of the problems existing in traditional tunnel clearance inspection methods, such as low density, slow speed and a lot of manual operations, this paper proposes a tunnel clearance inspection approach based on 3D point clouds obtained by a mobile laser scanning system (MLS). First, a dynamic coordinate system for railway tunnel clearance inspection has been proposed. A rail line extraction algorithm based on 3D linear fitting is implemented from the segmented point cloud to establish a dynamic clearance coordinate system. Second, a method to seamlessly connect all rail segments based on the railway clearance restrictions, and a seamless rail alignment is formed sequentially from the middle tunnel section to both ends. Finally, based on the rail alignment and the track clearance coordinate system, different types of clearance frames are introduced for intrusion operation with the tunnel section to realize the tunnel clearance inspection. By taking the Shuanghekou Tunnel of the Chengdu–Kunming Railway as an example, when the clearance inspection is carried out by the method mentioned herein, its precision can reach 0.03 m, and difference types of clearances can be effectively calculated. This method has a wide application prospects.

    Recent 121-year variability of western boundary upwelling in the northern South China Sea (2013)
    Wiley-Blackwell
    Details
    Publication Date: 2013-03-22
    Description: [1]  Coastal upwelling is typically related to the eastern boundary upwelling system (EBUS), whereas the powerful southwest Asian summer monsoon (ASM) can also generate significant cold, nutrient-rich deep water in western coastal zones. Here we present a sea surface temperature (SST) record (AD 1876-1996) derived from coral Sr/Ca for an upwelling zone in the northern South China Sea (NSCS). The upwelling-induced SST anomaly record reveals prominent multi-decadal variability driven by ASM dynamics with an abrupt transition from warmer to colder conditions in 1930, and a return to warmer conditions after 1960. Previous studies suggest the expected increase in atmospheric CO 2 for the coming decades may result in intensification in the EBUS, which could enhance upwelling of CO 2 -rich deep water thus exacerbating the impact of acidification in these productive zones. In contrast, the weakening trend since 1961 in the upwelling time series from the NSCS suggests moderate regional ocean acidification from upwelling thus a stress relief for marine life in this region.

    Cis-2-dodecenoic acid quorum sensing system modulates N-acyl homoserine lactone production through RpfR and cyclic di-GMP turnover in Burkholderia cenocepacia (2013)
    BioMed Central
    Details
    Publication Date: 2013-07-02
    Description: Background: Burkholderia cenocepacia employs both N-Acyl homoserine lactone (AHL) and cis-2-dodecenoic acid (BDSF) quorum sensing (QS) systems in regulation of bacterial virulence. It was shown recently that disruption of BDSF synthase RpfFBc caused a reduction of AHL signal production in B. cenocepacia. However, how BDSF system influences AHL system is still not clear. Results: We show here that BDSF system controls AHL system through a novel signaling mechanism. Null mutation of either the BDSF synthase, RpfFBc, or the BDSF receptor, RpfR, caused a substantial down-regulation of AHL signal production in B. cenocepacia strain H111. Genetic and biochemical analyses showed that BDSF system controls AHL signal production through the transcriptional regulation of the AHL synthase gene cepI by modulating the intracellular level of second messenger cyclic di-GMP (c-di-GMP). Furthermore, we show that BDSF and AHL systems have a cumulative role in the regulation of various biological functions, including swarming motility, biofilm formation and virulence factor production, and exogenous addition of either BDSF or AHL signal molecules could only partially rescue the changed phenotypes of the double deletion mutant defective in BDSF and AHL signal production. Conclusions: These results, together with our previous findings, thus depict a molecular mechanism with which BDSF regulates AHL signal production and bacterial virulence through modulating the phosphodiesterase activity of its receptor RpfR to influence the intracellular level of c-di-GMP.
