Geochemistry, zircon U–Pb geochronology, and Hf isotope data for the Early Paleozoic granites in the Baoshan Block reveal the Early Paleozoic tectonic evolution of the Proto-Tethys. The samples are high-K, calcalkaline, strongly peraluminous rocks with A/CNK values of 1.37–1.46, are enriched in SiO2, K2O, and Rb, and are depleted in Nb, P, Ti, Eu, and heavy rare earth elements,which indicates the crystallization fractionation of the granitic magma. Zircon U–Pb dating indicates that they formed in ca. 480 ma. The Nansa granites have εHf(t) values ranging from-16.04 to 4.36 with corresponding TC Dmages of 2.10–0.81 Ga, which suggests the magmas derived from the partial melting of ancient metasedimentary with minor involvement of mantle-derived components. A synthesis of data for the Early Paleozoic igneous rocks in the Baoshan block and adjacent(Tengchong,Qiangtang, Sibumasu, Himalaya, etc.) blocks indicates that these blocks were all aligned along the proto-Tethyan margin of East Gondwana in the Early Paleozoic. The Early Paleozoic S-type granites from Nansa were generated in a high-temperature and low-pressure(HTLP) extensional tectonic setting, which resulted from Andean-type orogeny instead of the final assembly of Gondwana or crustal extension in a non-arc environment. In certain places, an expanding environment may exist in opposition to the tectonic backdrop of the lithosphere’s thickening and shortening, leading the crust to melt and decompress,mantle-derived materials to mix, and a small quantity of peraluminous granite to emerge.

储能系统辅助火电机组二次调频具有响应速度快、跟踪精度高等优点,但功率分配不当会加速电池寿命衰减,导致运行成本增加,经济效益下降。如何制定合理的储能功率分配策略,在确保调频性能的同时延长电池寿命并提高经济效益,已成为亟待解决的重要问题。首先基于二阶RC等效电路建立储能锂电池的数学模型,采用限定记忆最小二乘递推算法辨识模型参数;随后,在火储联合调频模型的基础上,对基于比例、差额和频率的3种功率分配策略进行了仿真分析;最后,根据江苏某660 MW火电机组的实际运行数据,重点分析了不同策略对系统调频性能、电池寿命及经济性的影响。结果表明,比例分配策略的调频效果最差,且会加速电池寿命衰减;差额分配策略在调频性能上表现优异,但对电池寿命的改善有限;频率分配策略能够有效降低电池更换频率,可提高整体经济效益。总体而言,频率分配策略不仅可提高系统的调频能力,还能最大限度延长电池寿命并优化经济效益,在储能系统辅助火电机组二次调频中具有显著的应用优势。

The Lower Triassic Feixianguan Formation in the Daxian-Xuanhan region, northeastern Sicbuan is interpreted to be a carbonate platform intermediate between the West Hubei-East Cbongqing marine basin and Guangyuan-Wangcang marine basin. Outcrops, well logs and seismic data have disclosed that three sedimentary facies can be identified for the formation： open platform, platform exposed shoal and restricted platform facies. During the early stage of deposition of the Feixianguan Formation, there existed a sedimentary framework all the same as the Late Permian one： open platform in the west, and platform exposed shoal, restricted platform and open platform eastwards. The gradual increase of the shoal area permitted eastward migration of the shoal facies. During the deposition of the third member of the Feixianguan Formation, the study area was invaded by temporary transgressions. Till the deposition of the fourth member of the formation, the study area was prevailed over the unified restricted platform deposits, as indicated by the sedimentary model for the typical carbonate platform shoal deposits. The reservoir rocks in the Feixianguan Formation consist mostly of solution opening dolostone, and the rock types are assembled by oolitic dolostone, residual oolitic dolostone and sucrosic residual oolitic medium- to coarse-grained dolostone. The deep and shallow dual laterologs show relatively high resistivity, clear amplitude differences and time difference saltation of acoustic waves in some intervals. The seismic responses are indicated by low-frequency and highly variable amplitudes and chaotic reflection configurations. The reservoir rocks are characterized by high porosity-high permeability and medium porosity-medium permeability, showing a marked correlation between porosity and permeability. Solution openings are extremely developed in the reservoir rocks, including cast pores, intergranular solution openings, intercrystal pores, intercrystal solution openings, solu

There are different opinions about the Permian/Triassic boundary and its correlation in the Daxian-Xuanhan area because of lacking typical lithological symbols and fossil criterions. Especially, it is very hard to determine the Permian/Triassic boundary in the Daxian-Xuanhan buried areas. This brings many difficulties to geological research and oil and gas exploration. Based on field investigation and studies of well cores, newly found fossils, lithological characteristics and well log analyses, the authors discussed the Permian/Triassic boundary in the Daxian-Xuanhan area and brought forward a specific scheme for its determination and regional correlation.

通过对沙溪庙组三个砂岩样品进行碎屑锆石U-Pb定年,结果显示,其年龄区间呈现为五个年龄组,分别为2660~2300 ma,1905~1738 ma,1690~1442 ma,866~811 ma和298~160 ma。通过与周边区域不同地块(体)锆石年龄对比并综合区域相关地质资料,发现2660~2300 ma和1905~1738 ma两个年龄组的碎屑锆石主要来自南秦岭造山带与扬子板块北缘,少量来自碧口地体和松潘-甘孜地体;1690~1442 ma,该年龄组碎屑锆石来源于武关岩群、武当岩群及碧口杂岩;866~811 ma,该组碎屑锆石主要来源于扬子克拉通北缘、碧口岩群及南秦岭造山带;298~160 ma,碎屑锆石主要来自南秦岭造山带和晚三叠世的松潘-甘孜地体。以上证据表明,沙溪庙组物源主要来自南秦岭造山带及松潘-甘孜褶皱带,扬子克拉通则贡献较少,且南秦岭已于沙溪庙组之前隆升结束,阻挡了来自北秦岭及华北板块南缘的物质输入。

中国华南地区晚奥陶世末期—早志留世初期沉积五峰—龙马溪组黑色页岩的同时,也发育有多套钾质斑脱岩层,斑脱岩层的多次出现证实华南地区该时期曾间歇性发生了火山活动,但对于斑脱岩的来源尚存在分歧。本文选取了四川盆地多个五峰—龙马溪组剖面内发育较多层且厚度较大的斑脱岩为研究对象,通过野外考察和岩石矿物学、元素地球化学、锆石年代学等分析方法,对四川盆地五峰组—龙马溪组黑色页岩内所发育斑脱岩的年龄、火山活动持续时间及火山灰来源进行了分析研究。野外观察显示,钾质斑脱岩颜色醒目,易于区分,且具有一定的可塑性,多与黄铁矿条带或集合体共生。X衍射结果显示,其主要由黏土矿物和非黏土矿物组成,其中黏土矿物由伊利石和伊蒙混层组成,非黏土矿物以石英、长石、方解石、白云石和黄铁矿等为主。钾质斑脱岩主量元素以高K_(2)O含量、低TiO_(2)含量为特征,稀土元素成分分析显示,其轻稀土轻微富集、重稀土亏损,具负铕异常,球粒陨石标准化稀土配分曲线具有右倾的特点;对各斑脱岩内的锆石进行LA-ICP-MS定年研究,结果表明,斑脱岩的形成年龄在(448±2)ma~(440.4±5.6)ma之间,证实该时期火山活动延续了至少8 Myr;岩浆判别图(Nb/Y–Zr/TiO_(2))指示这些钾质斑脱岩的原始岩浆为中酸性成分;依据微量元素特征和构造环境判别图(Nb–Y,Y+Nb–Rb,Zr–TiO_(2),Hf/3–Th–Ta,Nb/Yb–Th/Yb),初步认为原始岩浆形成于岛弧环境。据斑脱岩层数及厚度自北向南逐渐减少的事实,及现阶段华南大地构造性质的新认识,认为其来源可能与扬子北缘早古生代秦岭洋闭合过程中的板块俯冲有关。
