辽宁本溪地区位于华北克拉通东部陆块东北部,区内广泛发育新太古代深成侵入岩和变质表壳岩,尚无钾质花岗岩的报道。钾质花岗岩的形成过程是早期陆壳发育成熟和稳定的重要标志,本次钾质花岗岩的发现对系统的研究华北克拉通早期陆壳的形成与演化具有重要的价值。本文对本溪地区马家沟的钾质花岗岩进行了岩石学、成岩年代学、岩石地球化学的研究,探讨了岩石成因和形成的构造背景。马家沟岩体为片麻状中细粒黑云母二长花岗岩。锆石U-Pb测年数据显示,岩石^(207)Pb/^(206)Pb加权平均年龄为(2490±21)Ma,形成于新太古代晚期。该岩体属弱过铝质、高钾钙碱性系列钾质岩石;主要富集高场强元素La、Zr、Th及大离子亲石元素K、Nd等元素,亏损P元素、高场强元素Nb和大离子亲石元素Sr、Ti等;REE曲线为右倾型,负Eu异常,属于S型花岗岩。研究区钾质花岗岩岩浆主要来源于地壳,是变质泥岩部分熔融的产物,形成于活动大陆边缘碰撞造山后的伸展环境,代表华北太古宙克拉通固结基底形成之前的最后一次岩浆活动,标志着在新太古代晚期本溪地区微陆块已拼贴完成,并与其他地区一起构成稳定的华北太古宙克拉通。

Objective The Mesozoic strata in eastern Liaoning and southern Jilin are relatively well developed. Liu et al.(1963) studied Lycoptera in North China, and they mentioned the fossils of south Jilin, but they were not included in the study due to the lack of specimens and poor preservation. Ma and Sun(1988) studied fish fossils from the Sankeyushu section in Tonghua, Jilin, and laid the foundation for the study of fish fossils in this area.

A New Understanding of the Lower Cretaceous Jiufotang Formation in Western Liaoning

Open Journal of Geology 2019年第10期9卷 658-660页

作者： zijie wu Longwei Qiu Haipeng Wang School of Geosciences China University of Petroleum Qingdao China Liaoning Provincial Institute of Geological Exploration Co. Ltd. Dalian China

The Lower Cretaceous Jiufotang Formation in western Liaoning is the most important fossil production horizon of the Jehol Biota, which is widely distributed in the Mesozoic basins of western Liaoning. Due to the influence of historical data, previous scholars believed that there was no volcanic activity in the Jiufotang Formation in western Liaoning. In a field investigation in western Liaoning, the authors discovered basalt and andesite in the Hujiayingzi bed. In addition, a conformable boundary was found between the Yixian and the Jiufotang formations. It indicates that both the Jiufotang Formation and the Yixian Formation are strata containing volcanic-sedimentary rocks, only differing in strength of volcanic activity.

Kidney transplantation is the gold standard for the treatment of end-stage renal diseases(ESRDs). However,the scarcity of donor kidneys has caused more and more ESRD patients to be stuck on the waiting list for transplant surgery. Improving the survival rate for renal grafts is an alternative solution to the shortage of donor kidneys. Therefore, real-time monitoring of the surgical process is crucial to the success of kidney transplantation, but efficient methods and techniques are lacking. Herein, a fluorescence technology based on bright, photostable and long-circulating aggregation-induced emission(AIE) active NIR-II nano-contrast agent DIPT-ICF nanoparticles for the whole-process monitoring and evaluation of renal transplantation has been reported. In the aggregated state, DIPT-ICF exhibits superior photophysical properties compared with the commercial dyes IR-26 and IR-1061. Besides, the long-circulating characteristic of the AIE nano-contrast agent helps to achieve renal angiography in kidney retrieval surgery,donor kidney quality evaluation, diagnosing vascular and ureteral complications, and assessment of renal graft reperfusion beyond renovascular reconstruction, which considerably outperforms the clinically approved indocyanine green(ICG).

随着多微网新能源渗透率不断提高,风电、光伏等新能源的随机性及不同运营主体间的利益博弈给传统经济调度模式带来挑战。为提高多微网系统安全性及经济性,提出了一种考虑风光互补特征的多微网系统自治经济调度方法。以多微网系统经济运行成本最优为目标,同时考虑多场景下的机组调节费用,基于Copula理论形成风电、光伏典型场景生成方法,运用目标级联分析法建立双层优化模型,实现微网、配电网自主独立优化。以IEEE 33节点系统为例,比较考虑风光相关性与仅考虑随机性情景的多微网系统经济性,并与集中式调度方法进行对比,验证了考虑风光互补特征的调度方法可提高系统经济性,并在极端场景时提高系统鲁棒性。
