The Triassic was a crucial period in the tectonic evolution of the South China Block. Research on tectonic deformation during this period provides information on intracontinental orogenic mechanisms in South China. In this study, alongside thermochronological analyses, we examine the macroscopic and microscopic structural features of the Rongxian ductile shear zone, located south of the Darongshan granite in the southeastern part of Guangxi Province, on the southern margin of South China. Sinistral shear is indicated by the characteristics of rotated sigma-type feldspar porphyroclasts, stretching lineations defined by elongated quartz grains and the orientations of quartz c-axes. LA-ICP-MS U-Pb dating of zircons from two samples of granitic mylonite and one of granite yielded ages of ca. 256 Ma. Furthermore, two samples of granitic mylonite yield muscovite Ar-40/Ar-39 plateau ages of 249-246 Ma. These results indicate that the Rongxian ductile shear zone resulted from Early Triassic deformation of the late Permian Darongshan granite. This deformation was likely related to the closure of the eastern Paleo-Tethys Ocean and the subsequent collision of the South China and Indochina blocks, during the early stage of the Indosinian orogeny.

糜棱岩的变质变形温度测定对其变形演化过程和热年代学同位素定年结果解释具有重要的意义.本文仅讨论各地质温度计在那卜韧性剪切带中的适用性.利用糜棱岩中的矿物组合、矿物动态重结晶特征以及EBSD(electron back-scattered diffraction)石英轴组构等塑性变形特征,估算出那卜韧性剪切带的变质变形温度范围为400~550℃.在电子探针分析技术基础上,利用绿泥石成分地质温度计、白云母-绿泥石地质温度计以及白云母/黑云母Ti温度计对那卜韧性剪切带中的花岗质糜棱岩样品进行变质变形温度计算,获得相应的温度分别为305~325℃、390~500℃、395~492℃和473~565℃、431~574℃.通过对比分析发现,利用绿泥石成分地质温度计获得的结果明显低于利用塑性变形特征估算出的温度范围和其他温度计的计算结果,结合前人研究结果表明其仅适用于低温变质变形作用的温度计算;而另外3种温度计获得的结果在误差范围内均位于利用塑性变形特征估算出的温度范围内,表明其均适用于该剪切带的变质变形温度计算.其中白云母-绿泥石地质温度计适用于低温糜棱岩,白云母/黑云母Ti温度计适用于相对高温的糜棱岩.

The certified power conversion efficiency(PCE)of per-ovskite solar cells which have emerged as the most promising candidates for next-generation thin-film photovoltaics has exceeded 25%.Among all available compositions,formamidinium lead iodide perovskite(FAPbI_(3))has a theoretically higher efficiency than the other perovskite analogues due to its narrower bandgap[1,2]and hence has attracted widespread attention.

公共数据的开发利用已经成为数字化时代不可回避的重要议题,寻求与大数据平台企业等主体展开合作是公共数据开发的重要趋势。政府与大数据平台企业合作开发公共数据受到资源互补、利益共享和风险共担三重因素共同驱动,而公共数据开发可能存在权力解构效应和权利诱导倾向,衍生出以“管制俘获、市场支配和公共意志裹挟”为代表的权力型风险和以“算法合谋、算法歧视、算法操纵和租值耗散”为代表的权利型风险。为此,可以通过明晰公共数据权属边界、落实公共数据权属责任、协调政企合作伙伴关系与激发政企合作主体动能等路径规避公共数据合作开发的潜在风险,真正走向公共数据价值共创。

Frequent offshore oil spill accidents, industrial oily sewage, and the indiscriminate disposal of urban oily sewage have caused seri- ous impacts on the human living environment and health. The traditional oil-water separation methods not only cause easily environmental secondary pollution but also a waste of limited resources. Therefore, in this work, three-dimensional (3D) graphitic carbon sphere (GCS) foams (collectively referred hereafter as 3D foams) with a 3D porous structure, pore size distribution of 25-200 μm, and high porosity of 62vol% were prepared for oil adsorption via gel casting using GCS as the starting materials. The results indicate that the water contact angle (WCA) of the as-prepared 3D foams is 130°. The contents of GCS greatly influenced the hydrophobicity, WCA, and microstructure of the as-prepared samples. The adsorption capacities of the as-prepared 3D foams for paraffin oil, vegetable oil, and vacuum pump oil were approximately 12-15 g/g, which were 10 times that of GCS powder. The as-prepared foams are desirable characteristics of a good sorbent and could be widely used in oil spill accidents.
