In situ zircon U-Pb geochronological and Lu-Hf isotope studies of detrital zircons from Late Mesoproterozoic to Early Neoproterozoic sedimentary units on the southwestern margin of the Yangtze Block have important implications for the tectonic evolution of the Yangtze Block.The Huili Group contains zircons whose ages are mainly Late Archean to Mesoproterozoic(2650-2450,2100-1800,and 1350-1150 Ma).The Dengxiangying Group has one major age population of 1900-1600 Ma,and two subordinate age populations of 1350-1100 and 2300-2000 Ma.Yanbian Group sedimentary rocks have a zircon age population mainly in the range of 970-850 Ma,contemporaneous with the ages of widespread arc-related magmatism in the western Yangtze Block.Combining these results with previous work,the Huili and Dengxiangying groups were most likely deposited during ca.1160 to 1000 Ma in an intra-continental rift basin setting,while the Yanbian Group accumulated during>920 to 782 Ma in a back-arc basin setting at the southwestern margin of the Yangtze Block.In addition,all these results further suggest a tectonic transition from a continental rift basin to a convergent environment at the southwestern margin of the Yangtze Block at 1000-970 Ma.

The Changchun–Yanji suture zone(CYSZ) in NE China is considered as the suture between the North China Craton(NCC) and Central Asian Orogenic Belt(CAOB). The geochronology, geochemistry and Sr-NdHf isotopes of Early–Middle Triassic adakitic plutions from the CYSZ, are presented in this paper to discuss their petrogenesis and tectonic setting, as well as to constrain the timing and style of the Paleo-Asian Ocean's final closure. In Early Triassic, the Dayushan pluton(ca. 250 Ma) from western CYSZ has negative ε_(Nd)(t) values, bidirectional provenances(NCC and CAOB) of ε_(Hf)(t), which are formed in a collision tectonic setting. In contrast, in eastern CYSZ, the early Triassic samples in Liangshan(ca. 242 Ma) were high Mg~# values, positive ε_(Nd)(t), single provenances(CAOB) of ε_(Hf)(t) resulting from a subduction setting. In the Middle Triassic, the Atype granites in western CYSZ are found in previous studies representing a post-collisional extensional environment, whereas syn-collisional Lianyanfeng granites(ca. 237 Ma) in eastern CYSZ with low ISr and large scale ε_(Nd)(t) and ε_(Hf)(t) values from bidirectional provenances(NCC and CAOB), represent a collisional setting. The Paleo-Asian Ocean's occurred in a scissor-like fashion along the CYSZ during the Triassic period.

Caledonian orogeny is another important tectonic event in South China Block after the breakup of the Rodinia supercontinent.With a view to constrain the tectonic evolution and proto-basin in South China,this paper reports the geochemical and zircon U-Pb dating data of the Ordovician strata in central Hunan,South China.Geochemical features and paleocurrent directions suggest that the lower Ordovician deposited in a passive continental margin basin with a provenance of quartzose components and showing an affinity with the Yangtze Block.U-Pb age data for 260 detrital zircons from upper Ordovician identify three major age populations as:900-1200 Ma,1400-1800 Ma and 2400-2700 Ma.The detrital zircon age spectrum as well as the paleocurrent directions suggest that upper Ordovician deposited in a foreland basin and showing a close affinity with the Cathaysia Block.It is also suggest that the lower Ordovician continuously accepted the mineral from the Yangtze Block,whereas the provenance of the upper Ordovician sedimentary basin changed from the Yangtze Block to the Cathaysia Block.This change implies a tectonic movement,which caused the transformation of the proto-basin in the Hunan area in SCB from passive continental margin basin to foreland basin probably took place during late Ordovician.This fact also demonstrate that the Caledonian orogeny in South China Block began no later than 453 Ma,and a new crustal evolution model is proposed.

为了实现铬污染盾构渣土的资源化利用,解决单一水泥固化材料用量大、排放量高以及固化效果不理想等问题,研制水泥基有机-无机复合固化剂固化铬污染盾构渣土。以14 d养护龄期固化土无侧限抗压强度和浸出毒性为评判指标,通过设计“五因素四水平”正交试验确定复合固化剂最佳配比;采用极差分析法对各影响因素进行主效应分析,并结合XRD和SEM试验探究复合有机-无机固化剂的作用机理。研究结果表明:无侧限抗压强度和浸出毒性评判指标的最优解均为11%(质量分数,下同)水泥、5.50%生石灰、0.25%聚丙烯酰胺、1.10%硅酸钠和0.05%海藻酸钠;14 d养护龄期的试验13(A4B1C4D4E1)固化土无侧限抗压强度达1217.58 kPa,重金属铬浸出质量浓度为2.4 mg/L,满足相关规范要求;水泥、海藻酸钠和硅酸钠为固化土无侧限抗压强度评判指标的主要影响因素,水泥、海藻酸钠和生石灰为浸出毒性评判指标的主要影响因素;固化土无侧限抗压强度与重金属铬浸出质量浓度密切相关,具体表现为固化土无侧限抗压强度越大,重金属铬的稳定化效果越明显;大量的自由水被消耗、pH升高、新矿物的生成、土体微观结构改变及土颗粒间胶结作用增强是盾构渣土性能提高的主要原因;当固化土强度增大时,重金属铬的物理封闭作用增强;此外,发生水化反应形成的较高pH也促进三价铬生成难溶于水的氢氧化物沉淀,从而降低固化土重金属铬浸出毒性。

This paper presents the results of combined studies of geochronology, geochemistry, whole rock Sr-Nd and zircon Hf-O isotopes carried out upon the rhyodacite and ignimbrite of Shangshu village, Shangyu town and Shanghupeng village of Jiangshan City in Zhejiang Province, along the northwestern side of the Jiangshan–Shaoxing suture. SHRIMP zircon U-Pb dating of samples in the three areas yielded weighted mean 206 Pb/238 U ages of 842.8 ± 6.9 Ma and 850.0 ± 7.3 Ma, 839 ± 9 Ma and 832.2 ± 8.1 Ma, 828.3 ± 8.5 Ma and 836.9 ± 9.9 Ma, respectively. These ages are older than the volcanic rocks of the Shangshu Formation dated at around 780 Ma distributed in Fuyang City, Hangzhou City, Kaihua County, etc. The volcanic rocks generally have high SiO2(54.08–76.80 wt%) and Al2 O3(12.40–21.31 wt%), low Fe2 O3(0.68–8.92 wt%), MgO(0.29–2.49 wt%), CaO(0.12–2.86 wt%), TiO2(0.10–1.59 wt%) and P2 O5(0.01–0.39 wt%), with variable total alkalis(K2 O + Na2 O =5.42–8.29 wt%). There exists a clear negative correlation between SiO2 and P2 O5. The volcanic rocks have A/CNK ratios of 1.03–2.77 and thus are peraluminous. They are characterized by enrichment in LREE, Rb, Ba, Zr, Hf, K, Th, La, U and depletion in Nb, Sr, P, Ti, with distinct LREE and HREE fractionation of(La/Yb)N values of 5.68–11.67, and with a moderate negative Eu anomaly(&Eu=0.58–0.89). Whole-rock geochemical data shows that the Jiangshan volcanic rocks are possibly I-type granitic rocks, even though they have some characteristics of A&S-type granites due to the magma fractional crystallization and water-rock interaction. Zircon δ18 O values are 3.97‰–5.49‰(average 4.50‰), 2.90‰–5.21‰(average 4.32‰) for ignimbrite from Shangshu village section, and Shanghupeng village section, respectively. They are slightly lower than the average δ18 O values of igneous zircons in equilibrium with mantle magmas(5.3 ± 0.6‰(2σ)), the lower δ18 O value also demonstrating the presence of high temperature water-rock interactions. The ignimbrite rocks have positive εNd(t)(4.02, 3.37, 3.91, 4.74, 2

Western Yunnan is composed of several extruded continental microblocks that were generated by the oblique collision between the Indian and Asian continents during the Cenozoic.In this study,the magmatic and tectonic frameworks of western Yunnan in the Cenozoic were analyzed based on geochemistry,Sr-Nd-Pb isotopes,and apatite/zircon fission track dating.Magmatism during the Cenozoic in western Yunnan was then divided into three distinctive episodes：alkali granite rocks produced from 55 to 46 Ma were derived from the anatexis of crustal materials;bimodal igneous rocks formed between 37 and 24 Ma were possibly derived from an EMII mantle with a contribution from continental materials;and intermediate-basic volcanic rocks produced in the Tengchong microblocks since-16 Ma are considered to be generated by the partial melting of the upper mantle that was induced by the pulling apart of the dextral Gaoligong strike-slip fault system.Moreover,fission track analysis of apatite and zircon indicates that the regional crustal uplift in western Yunnan possibly began at -34 Ma,with accelerated annealing occurring at -24 Ma,-13 Ma,and -4 Ma.During the past24 Ma,the average denudation rate was -0.32 mm/yr for the faulted block controlled by the Chongshan-Lancang River fault.However,crustal uplift has been relatively gentle in places lacking influence from strike-slip shear zones,with an average denudation rate of-0.2 mm/yr.Combined with strike-slip shear and block rotation in the Cenozoic,the tectonic evolution of western Yunnan since -45Ma can thus be divided into four stages occurring at 45-37 Ma,37-24 Ma,24-13 Ma,and 13-0 Ma.

To understand the change regions of pH and the effect on phytoplankton while the acidic effluent of desulfuration from power plants drai- ning into seawater, the changing modes of phytoplankton species and quantity to pH were established in seawater through laboratory survey in this work. Then, the ECOMSED model was applied to predict the change scope of pH and the ecological influences on phytoplankton due to the acidic effluent from a programming power plant in Zhanjiang Bay. The experimental results in laboratory showed that the species of phytoplankton changed with pH in a rule of convex parabola, and the quantity of phytoplankton decreased linearly with the fall of pH. The results of pH numerical simulation indicated that the acidic effluent from the power plant flowed zonally with tide. When the pH value of surface seawater decreased from the back- ground value of 8.0 to 7.8, the extreme area influenced harmfully by the acidic effluent was near 30.70 km2, accounting for about 16.2% of the to- tal area of Zhanjiang Bay （190 km2）. The predict results of ecological impact showed that if the species and quantity of phytoplankton decreased by 5% in surface seawater, the corresponding extreme areas influenced harmfully by the acidic effluent were 0.40 and 10.81 km2, accounting respec- tively for 0.21% and 0.53% of the total area of Zhanjiang Bay. Moreover, around the outlet of the power plant where the pH value of seawater was near to 6.8, the species and quantity of phytoplankton decreased most. However, the corresponding influenced area was rather small, just about 0.15 km2, accounting for 0.08% of the total area of Zhanjiang Bay.

塔里木盆地顺北地区4号断裂带发育典型凝析油气藏,凝析油气成因机制与富集主控因素不明制约了勘探向外围的拓展。基于有机地球化学特征与区域地质背景综合分析,明确了顺北4号断裂带凝析油气成因机制与富集主控因素,主要取得以下3点认识:(1)顺北4号断裂带发育原生的凝析油气藏,凝析油气藏的形成主要受到有机质差异演化,多期成藏以及次生作用影响。(2)顺北4号断裂带凝析油气藏整体次生作用较弱,但是中段和南段所经历的次生作用相对强于北段;次生作用包括原油裂解作用、气侵作用以及TSR作用。(3)顺北4号断裂带北段凝析油气藏富集程度明显高于中段和南段;凝析油气富集高产主要受到输导条件以及储层规模控制,断裂活动强度越大,输导条件越好,储层规模越大,膏盐岩越薄也越有利于油气沿走滑断裂向上运移,从而导致油气高产富集。
