古沙漠记录的沉积体系及层序地层研究进展——以鄂尔多斯盆地白垩系为例   总被引：2，自引：0，他引：2  

庞军刚  国吉安  李文厚  李卫红 《地层学杂志》2011,(1):95-102

鄂尔多斯盆地白垩纪古沙漠沉积地层主要为冲积扇、湖泊、河流、三角洲及沙漠沉积体系.风成沉积和沙漠沉积、风成沉积体系和沙漠沉积体系等概念有必要予以区分.基准面变化是沙漠和河流、湖泊等其他陆相地层对比的基础.鄂尔多斯盆地志丹群划分为上下两个三级层序单元,反映了两期古沙漠由风成沉积强盛期到衰退期的演化,且每个层序可划分为低位、...  相似文献   

2.5-D DC Resistivity Modeling Considering Flexibility and Accuracy     

汤井田  王飞燕  肖晓  张林成 《中国地质大学学报(英文版)》2011,(1)

We highlighted the flexibility of using unstructured mesh together with the local refinement by a resistivity model with complicated topography. The effect of topography is emphasized. Based on this, we calculated a specific class of layered models and found that the accuracy is not always satisfactory by utilizing the standard approach. As an improvement, we employed the layered earth as the reference model to calculate the wavenumbers. The comparison demonstrates that the accuracy is considerably improved...  相似文献   

Deposition Process of Dust Microparticles from Aerosol to Snow-Firn Pack on Glacier No. 1 in Eastern Tianshan Mountains, China     

尤晓妮  董志文 《中国地质大学学报(英文版)》2011,(4)

Samples were continuously collected from aerosol, fresh snow, and snow pits on Glacier No. 1 at Urumqi River source in eastern Tianshan (天山) Mountains. The deposition processes and the characteristics of mineral dust microparticles from aerosol to fresh snow, and then evolution to the snow pit were determined. Total dust microparticle concentration in the surface snow and aerosol showed a similar temporal variation trend, which was strongly associated with regional and local at-mospheric circulation in the ...  相似文献   

Tectonics and Mechanisms of Uplift in the Central Uplift Belt of the Huimin Depression     

倪金龙  郭颖  王智敏  刘俊来  林玉祥  李月 《中国地质大学学报(英文版)》2011,(3)

The Huimin (惠民) depression is a third-level tectonic element of the Bohai (渤海) Bay basin in eastern China. The central uplift belt is the most important oil and gas accumulation zone in the depression, but the lack of adequate geological studies in the area has greatly hindered exploration and development. In this article, using seismic data, fracture mechanics, and a combination of data on fault growth indices and fault throws, we present an analysis of tectonic activity in the central uplift belt and adja...  相似文献   

Anthropogenic Sulfate and Nitrate Signals in Snow from Bogda Glacier, Eastern Tianshan     

张晓宇  Ross Edwards 《中国地质大学学报(英文版)》2011,(4)

A 1.2 m snow pit was recovered on July 29th, 2009 from the Bogda Glacier, eastern Tianshan (天山). The sample site temperature of -9.6 ℃ indicates that the unique glaciochemical re-cord was well preserved and suitable for the reconstruction of air pollution levels in this previously un-explored region. Samples were analyzed for major ions (Na+, K+, Ca2+, Mg2+, NH4+, Cl-, SO42-, NO3-, HCOO-, and CH3COO-). NO3- and SO42- were characterized by significant high levels of pollution con-centration. Most air masses ...  相似文献   

Monitoring Glacial Shrinkage Using Remote Sensing and Site-Observation Method on Southern Slope of Kalik Mountain, Eastern Tian Shan, China     

王文彬  李开明  高建芳 《中国地质大学学报(英文版)》2011,(4)

Currently, one of the effective means in monitoring glacier change in regional scale is remote sensing and site-observation method. In this article, we present a study of comparing glacier area in 2005 derived from SPOT5 satellite image with area in 1972 derived from topographic maps. Moreover, Miaoergou (庙儿沟) flat-summit glacier is site observed to verify glacial change in regional scale. During the study period, glaciers located in the southern slope of Kalik (喀尔里克) Mountain re-duced their area by 12.3%. ...  相似文献   

雪峰山基底隆升带及其邻区印支期陆内构造特征与成因   总被引：7，自引：0，他引：7

狭义的华南陆块东部包括扬子地块和华夏地块,而雪峰山陆内构造系统是扬子地块的重要组成部分。通过对雪峰山地区印支期地层角度不整合时空分布规律的分析表明,高角度不整合—微角度不整合—平行不整合—整合的空间分布区域依次由东往西递变渐新。根据褶皱变形分析得出,雪峰山地区在印支期发育了北东东向和北北东向2个轴迹方向的褶皱,后期叠加了南北向弧形逆冲推覆构造。区域构造背景和动力学分析表明,扬子地块内部印支期总体北东向的变形形迹与东西轴向的秦岭—大别造山带和扬子地块南部东西轴向的构造线相垂直;其原因是:扬子地块与华夏地块最终陆内收缩变形的时间比扬子与华北沿秦岭—大别造山带的陆间碰撞拼合的时间早,印支早期的先存北北东向构造线在印支晚期由于扬子地块顺时针旋转变位为北东东向,从而决定了印支早期现今北东东向的构造线,随后的第二幕北北东向构造线的形成是在与早期第一幕变形的应力场相同的同一构造应力场作用下形成的。但是,秦岭—大别造山带近东西向的构造线取决于主动大陆边缘,即总体近东西向的华北陆块南缘边界,其原始方位为总体近东西向。这些复杂边界条件和旋转决定了先形成彼此近于垂直的构造线,然后拼接形成现今构造线垂直的格局。  相似文献   

减小离散误差的时频峰值滤波算法   总被引：1，自引：0，他引：1  

林红波  李月  徐学纯  马海涛 《吉林大学学报(地球科学版)》2011,41(2):572-578

提出减少时频峰值滤波分段点处阶跃误差的改进方法。经过研究时频峰值滤波在频率调制和时频平面峰值滤波时产生的离散误差以及尺度变换方式,发现分段点处阶跃误差与离散傅里叶变换的长度成反比,且与零点在尺度变换后产生的不确定值有关。提出基于定零点尺度变换的时频峰值滤波,在信号尺度变换时将零点变换到瞬时频率区间上的固定值,使各段时频峰值滤波零点偏移量一致,从而消除分段点处的阶跃误差。仿真实验和实际地震信号时频峰值滤波处理结果表明,改进的时频峰值滤波算法能够有效消减随机噪声,减少分段滤波在分段处的阶跃。  相似文献   

井外爆炸点源激发井孔声波场   总被引：1，自引：0，他引：1  

周来江  张玉君  崔志文  王克协 《吉林大学学报(地球科学版)》2011,41(1):299-304

利用井外爆炸点源激发的声波场与井孔的相互作用模拟井间地震的物理过程,推导了全频域井孔内外声波场的理论计算公式,并针对不同震源主频、不同源距(震源到井轴的径向距离)和软硬地层进行了井内声场的全波模拟与频率-相速度分析。结果表明:井外爆炸点源激发井孔内外的声场等效于无穷多级声场迭加的结果;震源靠近井壁时的频率-相速度图与震源在井内时相似;震源的主频越高、源距和接收器离井轴的径向距离越大、地层越硬,则顾及的多级声场的项数就要越多;震源主频越低、源距越小,井中激发的斯通利波则越强。  相似文献
