构造应力场研究可以为区域矿产预测提供依据。主要根据节理、擦痕的测试分析，结合区域构造解析，确定阿尔金山东西向拉配泉－－红柳沟构造带经历了三期不同方向的应力作用：印支期以前的南北向挤压作用，印支－燕山期的北西－南东向的挤压和中生代晚期－新生代北东东－南南西向的挤压；并利用有限元数值模拟前两期构造应力场的演变过程，进而讨论了区域构造应力场对内生金属矿产分布规律的控制作用指出了区域寻找大型内生金属矿产的有利地段。     

岷江上游干扰岸坡主要表生地质灾害分布特征及成因浅析

岷江上游地处我国著名的南北向地震带的中段，因其特定的地质环境导致区内表生地质灾害极为严重。通过对岷江上游（汶川以上）河段的崩塌、滑坡、泥石流等表生地质灾害的调查研究，其分布沿岷江两岸具有明显的分段特征与河谷地貌分段基本一致，它们形成发展与特定地形地貌、易崩滑或软弱地层、特殊的构造部位、降雨等密切相关。

黄骅裂谷盆地第三系水循环和渗流场形成演化的重溯

在简述盆地地质环境和含水系统、水文地质期与水压系统类型定位的基础上，通过建立数学模型，采用反演、比拟和地静压力等方法，模拟计算了各研究层在各研究时期泥岩压出水水头值（m),Es^2层的依次为2－28，2－26，2－6，2－16，0．5－3．5；Es^1层的依次为2－42，2－26，2－6，10－54，1－14；Ed层的依次为2－22，2－54，2－12；Ng层的依次为10－24，1－5；Nm层的为12－24。各研究层在各研究时期的压挤式水交替强度均小于1，累加值Es^2,Es^1,Ed层的均大于1，Ng，Nm层的小于1；Ed层渗入水交替强度为0.44。各研究层在各研究时期渗流场的高水压带位置和流动态具有相似性，并均以离心型流动型为主要特征。     

离散裂隙渗流方法与裂隙化渗透介质建模

流体渗流模拟的连续介质方法通常适用于多孔地质体，并不一定适用于裂隙岩体，由于裂隙分布及其特征与孔隙差异较大。若流体渗流主要受裂隙的控制，对于一定尺寸的裂隙岩体，多孔介质假设则较难刻划裂隙岩体的渗流特征。离散裂隙渗流方法不但可直接用于模拟裂隙岩体非均质性和各向异性等渗流特征，而且可用其确定所研究的裂隙岩体典型单元体及其水力传导（渗透）张量大小。主要讨论了以下问题：（1）饱和裂隙介质中一般的离散流体渗流模拟；（2）裂隙岩体中的REV（典型单元体）及其水力传导（渗透）张量的确定；（3）利用离散裂隙网络流体渗流模型研究裂隙方向几何参数对水力传导系数和REV的影响；（4）在二维和三维离散裂隙流体渗流模型中对区域大裂隙和局部小裂隙的处理方法。调查结果显示离散裂隙流体渗流数学模型可用来评价不同尺度上的裂隙岩体的水力特征，以及裂隙方向对裂隙化岩体的水力特征有着不可忽视的影响。同时，局部小裂隙、区域大裂隙应当区别对待，以便据其所起的作用及水力特征，建立裂隙化岩体相应的流体渗流模型。     

Identifying and quantifying urban recharge: a review

The sources of and pathways for groundwater recharge in urban areas are more numerous and complex than in rural environments. Buildings, roads, and other surface infrastructure combine with man-made drainage networks to change the pathways for precipitation. Some direct recharge is lost, but additional recharge can occur from storm drainage systems. Large amounts of water are imported into most cities for supply, distributed through underground pipes, and collected again in sewers or septic tanks. The leaks from these pipe networks often provide substantial recharge. Sources of recharge in urban areas are identified through piezometry, chemical signatures, and water balances. All three approaches have problems. Recharge is quantified either by individual components (direct recharge, water-mains leakage, septic tanks, etc.) or holistically. Working with individual components requires large amounts of data, much of which is uncertain and is likely to lead to large uncertainties in the final result. Recommended holistic approaches include the use of groundwater modelling and solute balances, where various types of data are integrated. Urban recharge remains an under-researched topic, with few high-quality case studies reported in the literature. Electronic Publication     

Far field effects of Alpine plate tectonism in the Iberian microplate recorded by fault-related denudation in the Spanish Central System

Apatite fission track analysis was performed on 56 samples from central Spain to unravel the far field effects of the Alpine plate tectonic history of Iberia. The modelled thermal histories reveal complex cooling in the Cenozoic, indicative of intermittent denudation. Accelerated cooling events occurred across the Spanish Central System (SCS) from the Middle Eocene to Recent. These accelerated cooling events resulted in up to 2.8±0.9 km of denudation in the western Sierra de Gredos and 3.6±1.0 km in the central and eastern Gredos (assuming a paleogeothermal gradient of 28±5 °C and a surface temperature of 10 °C). The greatest amount of denudation (5.0±1.6 km) occurred in the Sierra de Guadarrama. Accompanying rock uplift was 4.7±1.0 and 5.9±1.6 km in the eastern Gredos and Guadarrama, respectively. Most denudation in the Gredos occurred from the Middle Eocene to the Early Miocene and can be related to the N–S stress field, induced by the Pyrenean compression. In the Guadarrama, the greatest denudation was Pliocene to Recent of age and seems related to the ongoing NW–SE Betic compression. The fact that the formation of the E–W trending Gredos coincides with the N–S Pyrenean compression and the creation of the present day morphology of the NE–SW trending Guadarrama with the younger NW–SE Betic compression, indicates that they record the far field effects of Alpine plate tectonics on Iberia. The trend of pre-existing lineaments was of major importance in influencing the style and magnitude of these of far field effects.
