Orbitolinidae and Alveolinidae (Foraminiferida) from the uppermost Albian-lower Cenomanian of Monti d'Ocre (Abruzzi, Italy)

A biostratigraphic study carried out in the Monti d'Ocre area, Abruzzi, Central Apennines, allowed us to recognize Orbitolina (Conicorbitolina) moulladei ‘Strata 5 (1985) 1’, Praealveolina iberica Reichel and Praealveolina simplex Reichel in uppermost Albian–lower Cenomanian shelf-edge deposits of the Fossato Machè succession. These foraminifers have now been found for the first time in the Apennines of central Italy; their finding is quite important from a palaeobiogeographic viewpoint, as it contributes to the improvement of our knowledge on facies distribution in the circum-Mediterranean regions during the Cretaceous Period. In the study area, the coeval Monte Rotondo and Monte Orsello sections also crop out; these are characterized by bauxite deposits and stratigraphic gaps reflecting episodes of emergence on the carbonate platform. The Monte Rotondo and Monte Orsello sections accumulated in a platform back-reef environment; consequently, in this sector of the Monti d'Ocre area, the depositional environment shifted from a back-reef westward and southward to a shelf-edge northward, during the latest Albian–early Cenomanian. Owing to synsedimentary tectonics, the area investigated underwent differential subsidence: westward and southward, wide areas were uplifted and subjected to emergence, karstification and bauxite accumulation, whereas sedimentation continued in a shelf-edge environment in the north-eastern area.     

黑龙江省未来30、50年气候预测

通过CCCma、CCSR、CSIRO、Gfdl和Hadley气候模式对黑龙江省其中包括齐齐哈尔、佳木斯、哈尔滨、牡丹江等4区未来50年(2005～2050年)，在GG、GS情景下数值模拟。结果表明(采用GS结果)，未来2030、2050年气温均有较大增高。其中2030年年平均气温可增高1．94℃；春季提高2．06℃：；夏季提高1．29℃；秋季提高1．79℃；冬季提高2．66℃，2050年又继续增加．年平均气温将提高2．42℃；春季提高2．13℃；夏季提高1．68℃；秋季提高2．56℃；冬季提高3．21℃。冬季是四季中增幅最大的季节，其次秋季、春季和夏季。如果按GG情景下，未来气温还要高出1℃。增温中心在西部齐齐哈尔，增温较小为牡丹江。从哈尔滨年蒸发量来看，2030年可增加11％，2050年可增加13％。

利用数字图像处理技术提高地震剖面图像信噪比

提出了利用数字图像处理技术提高地震剖面信噪比的新方法，首先根据数字图像处理要求的格式，对地震剖面数据进行转换，得到地震剖面图像，分析了地震数据特点和初步地震图像的实验结果后，设计了新的预处理方法——“二维沿层滤波”，在此基础上，利用可以计算帧间运动速度及其变化都较大的改进的光流分析技术，计算出多幅地震剖面对应点的偏移量，然后应用图像积累技术对这多幅地震剖面进行积累，实现对三维地震数据体提高信噪比的处理，该方法充分利用了三维地震信息，不但可以提高整个数据体的信噪比，而且可以减少信号能量的损失，并保持原来的信号能量关系，使地震剖面的质量得到明显提高，为地震解释奠定良好的基础。     

采用基础摩擦隔震房屋高宽比限值的研究

大量的试验结果和地震经验表明，采用基础隔震方法能有效地提高建筑物的抗震能力，但建筑物的高度在什么范围，即建筑物的高宽比在什么范围内才适合采用这种方法，仍然是一个有待解决的课题。本文对采用基础滑移隔震多层砌体房屋在实际地震作用下的抗倾覆高宽比限值进行了研究，利用Ｗｉｌｓｏｎ－θ数值积分方法计算，得到了多层砌体房屋的高宽比限值的统计值。其数值结果可供编制建筑隔震设计规程参考。     

Partial melting during tectonic exhumation of a granulite terrane: an example from the Larsemann Hills, East Antarctica

Anatectic migmatites in medium- to low-pressure granulite facies metasediments exposed in the Larsemann Hills, East Antarctica, contain leucosomes with abundant quartz and plagioclase and minor interstitial K-feldspar, and assemblages of garnet–cordierite–spinel–ilmenite–sillimanite. Qualitative modelling in the system K₂O–FeO–MgO–Al₂O₃–SiO₂–H₂O–TiO₂–O₂, in conjunction with various P–T calculations indicate that the high-grade retrograde evolution of the terrane was dominated by decompression from peak conditions of c. 7 kbar at c. 800 °C to 4–5 kbar at c. 750 °C. Extensive partial melting during decompression involved the replacement of biotite by the assemblage cordierite–garnet–spinel within the leucosomes. These leucosomes represent the site of partial melt generation, the cordierite–garnet–spinel–ilmenite assemblage representing the solid products and excess reactants from the melting reaction. The extraction and accumulation of this decompression-generated melt led to the formation of syntectonic pegmatites and extensive granitic plutons. Leucosome development and terrane decompression proceeded during crustal transpression, synchronous with upper crustal extension, during a progressive Early Palaeozoic collisional event. Subsequent retrograde evolution was characterized by cooling, as indicated by the growth of biotite replacing spinel and garnet, thin mantles of cordierite replacing spinel and quartz within metapelites, and garnet replacing orthopyroxene and hornblende within metabasites. P–T calculations on late mylonites indicate lower grade conditions of formation of c. 3.5 kbar at c. 650 °C, consistent with the development of late cooling textures.

本文根据赣西北地区震旦系至志留系基本层序和板内构造演化,可把古板块构造发展划分为4个阶段:开裂期(Z_1l-Z_2p)以中、小规模的重力流和凝缩段为特征;成熟发展期(∈_1-∈_3~1),以沉降沉积作用为主;萎缩期(∈_3~2-O_2h)以大规模重力流和混生动物群为特征;闭合期(O_3-S_3)以双幕式沉积为特征。同时阐述了在板块发展的各个阶段,不能忽视其成矿作用。
