廖家坪金矿位于城步-桃江锑金多金属成矿带上。文章通过研究矿区地质特征、矿床地质特征、成矿规律分析等,进行找矿预测。区出露地层为震旦系、寒武系、奥陶系、志留系、泥盆系,其中奥陶系、志留系为金的主要赋矿地层。矿区西侧以NW向控矿和容矿构造为主,东侧以NE向控矿和容矿构造为主。矿区早期花岗岩与金矿形成密切相关。分析认为:城步-桃江深大断裂及其旁侧,印支早期花岗斑岩脉外接触带,构造变化及交汇部位,砂-泥质沉积岩建造及其NW向构造断裂带处,硅化、黄铁矿化、退色化的叠加部位及已发现金矿带的外围均为较好的找矿区域。

吉家洼金矿床位于豫西熊耳山金银多金属矿集区内,近年来其深部找矿取得了一定进展。为开展进一步找矿勘查工作,在吉家洼金矿区应用激电测深取得了较好的探测效果。视极化率对含矿地质体的反应较为敏感,激电测深在16勘探线以北探测到高极化地质体,推测深部存在自北东向南西方向延伸的隐伏含矿斑岩体。通过钻孔原生晕样品测试,发现16勘探线具有高温元素W异常,侧面验证了激电测深的预测结果。该研究结果对熊耳山金银多金属矿集区勘查脉状金银多金属矿化具有一定借鉴意义。

Vegetation cover pattern is one of the factors controlling hydrological processes. Spatially distributed models are the primary tools previously applied to document the effect of vegetation cover patterns on runoff and soil erosion. Models provide precise estimations of runoff and sediment yields for a given vegetation cover pattern. However, difficulties in parameterization and the problematic explanation of the causes of runoff and sedimentation rates variation weaken prediction capability of these models. Landscape pattern analysis employing pattern indices based on runoff and soil erosion mechanism provides new tools for finding a solution. In this study, the vegetation cover pattern was linked with runoff and soil erosion by two previously de- veloped pattern indices, which were modified in this study, the Directional Leakiness Index （DL[） and Flowlength. Although they use different formats, both indices involve connectivity of sources ,areas （interpatch bare areas）. The indices were revised by bringing in the functional heterogeneity of the plant cover types and the landscape position. Using both artificial and field verified vegetation cover maps, observed runoff and sediment production on experiment plots, we tested the indices＇ efficiency and compared the indices with their antecedents. The results illustrate that the modified indices are more effective in indicating runoff at the plot/hillslope scale than their antecedents. However, sediment export levels are not provided by the modified indices. This can be attributed to multi-factor interaction on the hydrological process, the feedback mechanism between the hydrological function of cover patterns and threshold phenomena in hydrological processes.

To accurately measure and evaluate reserves is critical for ensuring successful production of unconventional oil and gas. This work proposes a volumetric model to evaluate the tight sandstone gas reserves of the Permian Sulige gas field in the Ordos Basin. The reserves can be determined by four major parameters of reservoir cutoffs, net pay, gas-bearing area and compression factor Z, which are controlled by reservoir characteristics and sedimentation. Well logging, seismic analysis, core analysis and gas testing, as well as thin section identification and SEM analysis were used to analyze the pore evolution and pore-throat structure. The porosity and permeability cutoffs are determined by distribution function curve,empirical statistics and intersection plot. Net pay and gas-bearing area are determined based on the cutoffs, gas testing and sand body distribution, and the compression factor Z is obtained by gas component. The results demonstrate that the reservoir in the Sulige gas field is characterized by ultralow porosity and permeability, and the cutoffs of porosity and permeability are 5% and 0.15×10^(–3) μm^2, respectively. The net pay and gas-bearing area are mainly affected by the sedimentary facies, sand body types and distribution. The gas component is dominated by methane which accounts for more than 90%, and the compression factor Z of H_8(P_2h_8) and S_1(P_1s_1) are 0.98 and 0.985, respectively. The distributary channels stacked and overlapped, forming a wide and thick sand body with good developed intergranular pores and intercrystalline pores. The upper part of channel sand with good porosity and permeability can be sweet spot for gas exploration. The complete set of calculation systems proposed for tight gas reserve calculation has proved to be effective based on application and feedback. This model provides a new concept and consideration for reserve prediction and calculation in other areas.
