A4mthick bedded-chert sequence in the JifukudaniCreek, Tamba Terrane, SoutheastKyoto(SWJapan), yields Late Triassic conodonts.Metapolygnathus lindae, M. polygnathiformis, M.echinatus, M. primitius, Ancyrogondolella quadrata,A. spatulataand Mockina shamiseni spanthe Late Carnian polygnathiformis and primitiusbiozones, the Early Norian quadrata - spatulatabiozoneand the Middle Norian postera - shamisenibiozone. The Carnian - Norian boundarymay coincide in the field with a layer of blackclay. The conodont fauna shows affinities withboth the Tethys and Izanami Plateau of theIzanagi Plate, where the terranes of Japan originated,andto some extent with the WrangelliaTerrane (British Columbia, Canada).2008040566奥 地 利 北 钙 质 阿 尔 卑 斯 特 尔 奇 地 区 普 林 斯 巴阶 放 射 虫 : 再 造 特 提 斯 早 侏 罗 世 演 化 的 主 旨= Pliensbachian radiolarians in TeltschengrabenNorthern Calcareous Alps, Austria): a keystonein reconstructingthe Early Jurassic evolution ofthe Tethys. ( 英 文 ). O’Dogherty L; Gawlick H J.Stratigraphy, 2008, 5(1): 63-81In the “Hallstatt Mélange” in northwest BadMitterndorf, a slide of earliest late Pliensbachianmarly radiolarites occurs in an upper-Middle tolower-Upper Jurassic succession. The successionconsists of radiolarites, cherty limestones andmarls, dated by radiolarians as upper-MiddleJurassic (Callovian) and different slides of Triassicto early Jurassic age derived from the Hallstattfacies zone. The facies and lithology(mainly cherty sediments) of the Pliensbachianslide arenearly identical to those of the succession,but it belongs to the Lower JurassicDürrnberg Formation of the outer-shelf area ofthe Northern Calcareous Alps (Hallstatt Zone),which was paleogeographically situated in thenorth-western rim of the Neotethys Ocean. Theradiolarian fauna has low diversity but its goodpreservation allows an accurate age determination.The dating of the cherty slide as earliestlate Pliensbachian is of great importance because:1) it is the fi rst record of sedimentsyounger thanSinemurian in the Hallstatt Zone of the NorthernCalcareous Alps; 2) it is the first record ofPliensbachianradiolarians in the European Alpinearea; 3) it confi rms that the northwesternpassive margin of the Neotethys Oceanpersistedin this region at least until the Pliensbachian.Our paleontological and stratigraphic data provethat the closureof the Neotethys Ocean in thisregion is younger than earliest late Pliensbachian,but older than Callovian. The completeradiolarianfauna is illustrated and described. Fourteentaxa are identifi ed to species level, fromwhich one new genus Paradroltusand two newspecies Paradroltus mitterndorfensis and Lantussutnal are formally described.2008040567川 东 北 宣 汉 - 达 县 地 区 二 叠 纪 、 三 叠 纪 界 线 及其 相 关 性 = Permian/Triassic Boundary and ItsCorrelation in the Daxian-Xuanhan Area, NortheasternSichuan Province, China.

Acta GeologicaSinica, 2008, 82(1): 56-62There are different opinions about the Permian/Triassicboundary and its correlation in theDaxian-Xuanhan area because of lacking typicallithological symbols and fossil criterions.Especially,itis very hard to determine thePermian/Triassic boundary in the Daxian-Xuanhan buried areas.This brings many difficultiesto geological research and oil and gas exploration.Basedon field investigation and studies ofwell cores,newly found fossils,lithological characteristicsand well log analyses,the authors discus...2008040568综 评 华 北 侏 罗 纪 大 地 构 造 = Jurassic Tectonicsof North China:A Synthetic View.

Acta Geologica Sinica, 2008, 82(2):310-326This paper gives a synthetic view on the Jurassictectonics of North China,with an attemptto propose a framework for the stepwise tectonicevolution history.Jurassic sedimentation, deformationand magmatism in North China havebeen divided into three stages.The earliest Jurassicis marked by a period of magmatism quiescence(in205-190 Ma)and regional uplift,whichare considered to be the continuation ofthe"Indosinian movement"characterized by continent-continentcollision between the North andSo...2008040569中 国 侏 罗 纪 大 地 构 造 演 化 及 燕 山 运 动 新 解 =Jurassic Tectonic Revolution in China and NewInterpretation of the “Yanshan Movement”.
