莺－琼盆地YA13－1气田热流体活动与有机／无机成岩响应

根据钻井中途测试（ＤＳＴ）、重复地层测试（ＲＦＴ）、镜质体反射率（Ｒ０）、流体包裹体分析和粘土矿物Ｘ射线衍射全定量分析等综合研究发现，莺－琼盆地ＹＡ１３－１气田存在４期热流体活动；南侧的崖南地区和西侧的莺歌海盆地是其两个重要的热流体物质源和动力源；多期热流体活动在ＹＡ１３－１地区不仅造成热异常和物质迁移，而且还引起了不同的有机／无机成岩响应，如骨架颗粒的多期溶蚀作用、至少两期的次生加大作用、粘土矿物转化和有机质热成熟作用异常。第二、第三期热流体因出溶作用形成ＹＡ１３－１气田大规模的天然气聚集。

Interrelation between fault zone structures and earthquake processes

In order to develop capabilities for predicting earthquake processes on the basis of known fault zone structures and stress conditions, we need to find relations between seismogenic structures and processes. In the present paper we search for the scale dependence in various earthquake phenomena with the hope to find some structures in the earth that may control the earthquake processes. Among these phenomena, we shall focus on (1) geologic structures which play some role in nucleation and stopping of earthquake fault rupture, (2) depth ranges of the brittle seismogenic zone, (3) asperities and barriers distributed over a fault plane, (4) source-controlledf _max effect, (5) nonfractal behavior of creep events, and (6) temporal correlation between codaQ ^–1 and seismicity of earthquakes with magnitude characteristic to a given area. Our review of various scale-dependent phenomena leads us to propose a working hypothesis that the temporal change in codaQ ^–1 may reflect the activity of creep fractures near the brittle-ductile transition zone.

为了通过预测单桩沉降量去估算其极限承载力,基于静载荷试验所得的桩基沉降量具有灰指数律特征,将荷载Q看作广义的时间,建立了荷载序列的等步长及非等步长GM （1,1）预测模型.工程实例证明,所建立的灰色预测模型具有较好的实用性和创新性.     

The radio frequency dielectric properties of the stratified UG1–UG2 geological unit in the Bushveld Complex

A new measurement technique enables the complex dielectric properties of the geological strata comprising the UG1–UG2 (Upper Group 1–Upper Group 2) unit of the Bushveld Complex in South Africa to be determined with unprecedented detail at radio frequencies (RF). Results of non-destructive laboratory measurements of representative diamond drill core samples from the UG1–UG2 unit are presented at 25 MHz. These data establish that the UG1 and UG2 chromitite layers are embedded in rock strata (norite, pyroxenite and anorthosite) which are translucent in the HF spectral band, whereas the chromitite layers themselves exhibit significant velocity contrast, making them good radar reflectors. The data presented here is useful for calibration of the radar system, and for predicting the range and resolution performance of borehole radars operating in both the hanging and footwalls of the economically important platiniferous UG2 reef.     

Study of the erosion rates in the upper Maracujá Basin (Quadrilátero Ferrífero/MG,Brazil) by the in situ produced cosmogenic 10Be method

The present work quantifies the erosive processes in the two main substrates (schists–phyllites and granites–gneisses) of the upper Maracujá Basin in the Quadrilátero Ferrífero/MG, Brazil, a region of semi‐humid tropical climate. Two measuring methods of concentration were used: (i) in situ produced ¹⁰Be in quartz veins (surface erosion rates) and (ii) ¹⁰Be in fluvial sediments (basin erosion rates). The results confirm that (i) erosion tends to be more aggressive close to the headwaters than in the lower parts of the basin and (ii) the region is now affected by dissection.

沁水煤田霍东地区山西组主要煤层对比

运用标志层、层间距、物性特征、煤层本身特征等方法，对霍东地区沁安矿区和沁源矿区山西组1号、2号、3号煤层进行对比，认为沁安矿区未沉积3号煤层，该矿区现有的两个煤与沁源矿区的1号、2号煤层可比，而不是2号、3号煤层，其中既有定性又有定量，较成功的解决了南北两大矿区山本组主要可采煤层间的对比问题。     

基于MEM1谱分析的水文时间序列隐含周期特性研究

水文时间序列的隐含周期(本文将简单周期、复合周期及近似周期等统称为隐含周期)的识别、判定是一个重要而又较为困难的问题,相对成熟和有效的做法是对其进行频谱分析。建立在最大熵原理(POME)基础之上的MEM1谱分析,克服了传统谱分析方法的诸多不足,具有频谱光滑、分辨率高等独特优势。为此,以黄河花园口(秦厂)测站年径流系列、月径流系列和年最大洪峰流量序列隐含周期特性的研究为例,探讨了MEM1谱分析在水文时间序列隐含周期特性中的应用。
