太古宙克拉通型下地壳剖面：华北怀安－丰镇－尚义的麻粒岩－角闪岩系

华北克拉通北缘晋冀内蒙交界地区有变质程度连续变化、从高压基性麻粒岩、麻粒岩到角闪岩相的变质岩系出露。它们的古变质压力由＞１．４ＧＰａ（５０ｋｍ）变化到０．５ＧＰａ（１５ｋｍ）；岩石类型从变辉长岩、中酸性正片麻岩到表壳岩变化；变质矿物组合由不含水的耐火组合变为富含云母和角闪石的组合；地球化学性质表现出从贫Ｓｉ和Ａｌ、轻度亏损生热元素到具有正常的化学成分的连续变化；包裹体流体性质在轻度亏损生热元素的麻粒岩中均为ＣＯ２流体，而在麻粒岩相的表壳岩和角闪岩系中Ｈ２Ｏ流体逐渐增加。上述变质岩系剖面的组成和特点符合大陆下地壳的定义，可能代表了包括最下部地壳在内的华北地块太古宙克拉通型大陆下地壳。据此本文建立了我国第一条克拉通型大陆下地壳剖面，并讨论其地质意义以及相关的问题     

中国长江主要灾害与整治

由于江水和人类活动，引发长江崩塌、淤寒、洪涝和污染等灾害。研其原因主要为水动力改变；自然环境变化；人为破坏。整方案应采取治沙，营造“森林水库”；治水，按水动力学运动规律，用蓄、疏堵等手段综合治理；治污，要彻底根治污源；养殖，大力发展养殖业，促使生态平衡。     

Conditional curvilinear stochastic simulation using pixel-based algorithms

In geology, structures displaying differing local directions of continuity are widespread, a typical example being a flusial depositional system. Conventional pixel-based geostatistical algorithms, may fail to reproduce such curvilinear structures. Conversely, object-based algorithms can reproduce curvilinear shapes but are difficult to condition to dense local data. Local depositional directions as obtained from dipmeter data. 3D seismic data, and geological interpretation represent critical information. An improved pixel-based geostatistical algorithm is proposed to account for such directional information. Case studies demonstrate the potential and limitations of the algorithm.     

A traverse through the western Kunlun (Xinjiang,China): tentative geodynamic implications for the Paleozoic and Mesozoic

The northern part of the western Kunlun (southern margin of the Tarim basin) represents a Sinian rifted margin. To the south of this margin, the Sinian to Paleozoic Proto-Tethys Ocean formed. South-directed subduction of this ocean, beneath the continental southern Kunlun block during the Paleozoic, resulted in the collision between the northern and southern Kunlun blocks during the Devonian. The northern part of the Paleo-Tethys Ocean, located to the south of the southern Kunlun, was subducted to the north beneath the southern Kunlun during the Late Paleozoic to Early Mesozoic. This caused the formation of a subduction-accretion complex, including a sizeable accretionary wedge to the south of the southern Kunlun. A microcontinent (or oceanic plateau?), which we refer to as “Uygur terrane,” collided with the subduction complex during the Late Triassic. Both elements together represent the Kara-Kunlun. Final closure of the Paleo-Tethys Ocean took place during the Early Jurassic when the next southerly located continental block collided with the Kara-Kunlun area. From at least the Late Paleozoic to the Early Jurassic, the Tarim basin must be considered a back-arc region. The Kengxiwar lineament, which “connects” the Karakorum fault in the west and the Ruogiang-Xingxingxia/Altyn-Tagh fault zone in the east, shows signs of a polyphase strike-slip fault along which dextral and sinistral shearing occurred.
