1Geological Evidence for the Operation of Plate Tectonics throughout the Archean:Records from Archean Paleo-Plate Boundaries显示文摘Plate tectonics describes the horizontal motion of rigid lithospheric plates away from midoceanic ridges and parallel to transforms, towards deep-sea trenches, where the oceanic lithosphere is subducted into the mantle. This process is the surface expression of modern-day heat loss from Earth. One of the biggest questions in Geosciences today is 'when did plate tectonics begin on Earth' with a wide range of theories based on an equally diverse set of constraints from geology, geochemistry, numerical modeling, or pure speculation. In this contribution, we turn the coin over and ask 'when was the last appearance in the geological record for which there is proof that plate tectonics did not operate on the planet as it does today'. We apply the laws of uniformitarianism to the rock record to ask how far back in time is the geologic record consistent with presently-operating kinematics of plate motion, before which some other mechanisms of planetary heat loss may have been in operation. Some have suggested that evidence shows that there was no plate tectonics before 800 Ma ago, others sometime before 1.8–2.7 Ga, or before 2.7 Ga. Still others recognize evidence for plate tectonics as early as 3.0 Ga, 3.3–3.5 Ga, the age of the oldest rocks, or in the Hadean before 4.3 Ga. A key undiscussed question is: why is there such a diversity of opinion about the age at which plate tectonics can be shown to not have operated, and what criteria are the different research groups using to define plate tectonics, and to recognize evidence of plate tectonics in very old rocks? Here, we present and evaluate data from the rock record, constrained by relevant geochemical-isotopic data, and conclude that the evidence shows indubitably that plate tectonics has been operating at least since the formation of the oldest rocks, albeit with some differences in processes, compositions, and products in earlier times of higher heat generation and mantle temperature, weaker oceanic lithosphere, hotter subduction zones caused by more slab-melt generation, and under different biological and atmospheric conditions.Timothy M.Kusky Brian F.Windley Ali Polat 2018Journal of Earth Science2018,29,6:20

4Sea-Floor Metamorphism Recorded in Epidosites from the ca.1.0 Ga Miaowan Ophiolite,Huangling Anticline,China显示文摘The epidosites are interpreted to form in upflow zones at the base of ore-forming oceanic hydrothermal systems that vent as black smokers on the sea floor. This study presents new field, major and trace element, and oxygen isotope data for the recently discovered epidosites in the ca. 1.0 Ga Miaowan (庙湾) ophiolite located near the northern margin of the Yangtze craton. The epidosites occur mainly in the cores of strongly deformed, lensoidal amphibolites. Field observations, major and trace elements and oxygen isotopes suggest that the epidosites were formed by metasomatism of ocean floor basalts, diabase dykes, and gabbros during seafloor hydrothermal alteration.王军鹏 Timothy M Kusky Ali Polat 王璐 彭松柏 蒋幸福 邓浩 王淞杰 2012Journal of Earth Science2012,23,5:5
5Efficacy of ankaferd blood stopper application on nonvariceal upper gastrointestinal bleeding显示文摘AIM:To prospectively assess the hemostatic efficacy of the endoscopic topical use of ankaferd blood stopper(ABS) in active non-variceal upper gastrointestinal system(GIS) bleeding.METHODS:Endoscopy was performed on 220 patients under suspiciency of GIS bleeding.Patients with active non-variceal upper gastrointestinal bleeding(NVUGIB) with a spurting or oozing type were included.Firstly,8-10 cc of isotonic saline was sprayed to bleeding lesions.Then,8 cc of ABS was applied on lesions in which bleeding continued after isotonic saline application.The other endoscopic therapeutic methods were applied on the lesions in which the bleeding did not stop after ABS.RESULTS:Twenty-seven patients had an active NVUGIB with a spurting or oozing type and 193 patients were excluded from the study since they did not have non-variceal active bleeding.8 cc of ABS was sprayed on to the lesions of 26 patients whose bleeding continued after isotonic saline and in 19 of them,bleeding stopped after ABS.Other endoscopic treatment methods were applied to the remaining patients and the bleeding was stopped with these interventions in 6 of 7 patients.CONCLUSION:ABS is an effective method on NVUGIB,particularly on young patients with no coagulopathy.ABS may be considered as part of a combination treatment with other endoscopic methods.Gokhan Gungor M Hakan Goktepe Murat Biyik Ilker Polat Tuncer Tuna Huseyin Ataseven Ali Demir 2012World Journal of Gastrointestinal Endoscopy2012,4,12:5
6Debris flow susceptibility and propagation assessment in West Koyulhisar, Turkey显示文摘Turkey is highly prone to landslides because of the geological and geographic location.The study area,which is located in a tectonically active region,has been significantly affected by mass movements.Flow type landslides are frequently observed due to this location.This study aims at determining the source area and propagation of debris flows in the study area.We used the heuristic method to extract source areas of debris flow,and then used receiver operating characteristic(ROC)curve analysis to assess the performance of the method,and finally calculated the Area under curve(AUC)values being 83.64%and 80.39%for the success rate and prediction rate,respectively.We calculated potential propagation area and runout distance with Flow-R software.In conclusion,the obtained results(susceptibility map,propagation and runout distance)are very important for decisionmakers at the region located on an active fault zone,which is highly prone to natural disasters.The outputs of this study could be used in site selection studies,designing erosion prevention systems and protecting existing human-made structures.Ali POLAT Dursun ERİK 2020Journal of Mountain Science2020,17,11:4
7Paleozoic convergence processes in the southwestern Central Asian Orogenic Belt:Insights from U–Pb dating of detrital zircons from West Junggar,northwestern China显示文摘The West Junggar orogen,located in the southwestern Central Asian Orogenic Belt(CAOB),preserves an abundant record of tectonic processes associated with the evolution of the Junggar Ocean.In this study,we use detrital zircon U–Pb age data from Ordovician to Carboniferous sandstones in the southern and central West Junggar domains,complemented by literature data,to better constrain the tectonic evolution of the southwestern CAOB.The Kekeshayi,Qiargaye,and Laba formations in the southern West Junggar domain were deposited during the Darriwilian-Sandbian,Katian-Aeronian,and Homerian-Emsian,respectively.Detrital zircon provenances of these formations display a marked shift from the southern West Junggar domain to the Paleo-Kazakhstan Continent(PKC).This suggests that the southern West Junggar intra-oceanic arc might have gradually accreted to the northern margin of the PKC prior to the Emsian,which has significantly contributed to the lateral growth of the PKC.The Carboniferous strata,Xibeikulasi,Baogutu,and Tailegula formations,in the central West Junggar domain represent a coherent sequence of volcaniclastic turbidites and were deposited in a progressively shrinking remnant oceanic basin during the Visean to Moscovian.They contain unimodal detrital zircon distributions and are derived from the local and coeval magmatic rocks in the central West Junggar domain.We propose that the final closure of the Junggar Ocean likely occurred in the end of the Late Carboniferous in response to regional amalgamation events in the southwestern CAOB,which marks the final assembly of the Kazakhstan Orocline.The central and southern West Junggar domains underwent individual evolution in the Paleozoic,and were recombined by the significant intra-continental reworking along the large-scale strike-slip faults.Pan Zhang Guocan Wang Tianyi Shen Ali Polat Chengyu Zhu 2021Geoscience Frontiers2021,12,2:3
