Marine controlled source electromagnetic (CSEM) is an efficient method to explore ocean resources. The amplitudes of marine CSEM signals decay rapidly with the measuring offsets. signal easily contaminated by various kinds noise when offset large. These include instrument internal noise, dipole vibration seawater motion and environmental Suppressing key improve data quality interpretation accuracy. Sparse representation based denoising has been used for a long time. provides new way remove...
Abstract Kaolinite-rich rocks are widespread in Chinese coal-bearing strata. Three main types of deposits recognized. Those identified as flint clays several metres thick and show lateral variations bed composition. The kaolinite is thought to have formed mainly on the adjacent landmass, but some crystallization gels within basin not ruled out. Tonsteins, which from situ alteration airfall volcanic ashes, very common coal measures up 0.5 m thick. Finally, described where development kaolin...
Magmatic fluids and leaching of rocks are regarded as the two sources magmatic hydrothermal deposits, but their relative contributions to metals in deposits still unclear. In this study, we combine major elements Fe isotopes sets from Han-Xing iron skarn deposit China constrain sources. The positive correlation between δ56Fe ∑Fe2O3/TiO2 altered diorites (∑Fe2O3 refers total iron) demonstrates that heavy preferentially leached during alteration. However, except for pyrite, all minerals formed...
The structures, sedimentary fill and magmatic rocks of basins are the products regional tectonic evolution crucial to studying basin's tectonic–palaeogeographical environment evolution. present study discusses zircon U–Pb dating volcanic rock samples, in situ Hf isotope whole-rock geochemistry analysis, palaeogeographical, filling background Bayingobi basin through outcrop core descriptions Meso-Cenozoic strata, stratigraphic correlation lithofacies analysis. age is 132–102 Ma, isotopic...
Remotely sensed image high-accuracy interpretation (RSIHI), including tasks such as semantic segmentation and change detection, faces the three major problems: (1) complementarity problem of spatially stationary-and-non-stationary frequency; (2) edge uncertainty caused by down-sampling in encoder step intrinsic noises; (3) false detection imagery registration error detection. To solve aforementioned problems, an uncertainty-diffusion-model-based high-Frequency TransFormer network (UDHF2-Net)...
Purpose Idiosyncratic deals (i-deals) are designed to benefit both the employees and employers. While plenty of previous studies uncover outcomes i-deals, little research has explored what drives organizations adopt i-deals in first place. Drawing on transaction cost economics theory, this paper aims investigate how employee–employer exchange characteristics affect different types i-deals. Design/methodology/approach Based a two-wave questionnaire study 385 from information technology...
Tamusu uranium deposit is located in Yingejing sag the Bayingobi basin. A rift type structural slope zone developed northwest of sag. Based on study lithology, lithofacies, whole rock geochemistry, and fluid inclusion characteristics deposit, a paragenetic association sequence altered minerals was established, source, temperature, salinity, evolution ore-forming were discussed. The stratigraphic assemblage structure lower member Formation (falling-stage system tract, lowstand transgressive...
Abstract The compositions of minerals and whole rocks the Luobusa ophiolite in South Tibet, a fragment Neo‐Tethyan forearc lithosphere, is used to investigate magmatic evolution nascent mantle wedges newly‐initiated subduction zones. Clinopyroxenes peridotites all have diopsidic compositions, their Al 2 O 3 contents vary from ∼ 2% dunites refractory harzburgites 2‐4% cpx‐bearing harzburgites. REE clinopyroxenes left‐sloping patterns with comparable those abyssal that experienced 5‐15%...
Earth-filled dams are prone to serious erosion and seepage by water flow. Anomalous is a threat the stability of dam structures common hydrogeological hazard in engineering. It great significance clarify paths for targeted remediation. In this paper, we present joint use self-potential (SP) electrical resistivity tomography (ERT) methods characterize an earth-filled dam, where there already evidence abnormal seepage. The ERT provides effective information on structure dam. SP data aims...
Abstract. The self-potential (SP) method is a sensitive geophysical means to locate seafloor polymetallic sulfide deposits. A reasonable SP forward modeling can provide good foundation for inversion and interpretation of the measured data. We propose solve analytical solution generated by regularly polarized bodies in layered media. Based on mirror image current theory, new formula was derived clarified detail models. also discussed models with different numbers layers through numerical...
Marine controlled source electromagnetic (CSEM) method is widely used for submarine resources detection. The amplitudes of marine CSEM signals decay exponentially with the augment offset. When offset large, are easily contaminated by various kinds noises, such as internal dipole vibration sea water motions noises and so on. Suppressing influence key to improve data accuracy. Nowadays, most denoising methods aim at removing single type Gaussian white noises. Sparse representation provides a...
