With practical examples,the present paper has expounded the geochemical prospecting method for investigating and verifying hydrochemical anomalies in the basalt-covered area of southern Jilin.An integrated study of the available geological data shows that geological conditions of the Yanjiangcun and Malugou hydrochemical anomalous districts in southem Jilin are favorable for mineralization.Combined with microlandscape characteristics and applying mercury-vapor survey,the authors delineated the extension of the...

With practical examples,the present paper has expounded the geochemical prospecting method for investigating and verifying hydrochemical anomalies in the basalt-covered area of southern Jilin.An integrated study of the available geological data shows that geological conditions of the Yanjiangcun and Malugou hydrochemical anomalous districts in southem Jilin are favorable for mineralization.Combined with microlandscape characteristics and applying mercury-vapor survey,the authors delineated the extension of the fault structural zone in an area of 2km2 within the Yanjiang anomalous district.Rock profile and soil survey show that the structure has experienced hydrothermal mineralization and the mineralized body is buried at a rather great depth.On the basis of soil survey,the target area for verification was selected through optimization,and then a gold mineralized body 30m in thickness was revealed by drilling below the depth of 620m,with the highest Au content being 1.5g/T.In the Malugou hydrochemical anomalous district,follow-up for anomaly was conducted by means of stream sediment survey and,as a result,the"target area"for ore prospecting was rapidly reduced. Further follow -up work in the"target area"by means of heavy mineral survey led to the discovery of gold mineralization source.On such a basis,a metallogenic prospect area in which a volcanic epithermal gold deposit is likely to be found was delineated through large-scale soil survey combined with rock survey.

本文通过实例,介绍了吉南玄武岩覆盖区水化学异常查证的化探工作方法。综合研究已有地质条件,认为吉南沿江村、马鹿沟水化学异常地区成矿地质条件有利。结合微景观特点,在沿江异常区2km2范围内应用汞气测量圈出区内断裂构造带展布方向。岩石剖面、土壤测量显示出构造经历过热液矿化活动,矿化体埋藏较深。根据土壤测量结果优选出验证靶区。钻探验证结果在地表620m以下发现了近30m厚的Au矿化体,Au含量最高1.5g/t。马鹿沟水化学异常区使用水系沉积物测量进行异常追踪,迅速缩小了找矿“靶区”。使用重矿物测量在“靶区”内进一步追踪发现了Au矿化源。在此基础上经大比例尺土壤测量辅以岩石剖面测量,圈出了一个有望找到火山岩型浅成热液金矿床的成矿远景区。

Facing to the tiny landscape in the area we choose soil and river sediment measurements for 1:20000 geochemical survey. Sampling tests show that grain size (-5 mesh~+20 mesh) of sampling medium from residual, slope sediments or fluvial sediments is proper. Four sheets of such gechemical survey outline significant anomalies with effective ore-searing result.

 内蒙古二连浩特市—东乌珠穆沁旗地区属半干旱荒漠草原区。1∶20万区域化探扫面应针对该类景观区微景观特点,选择土壤或水系沉积物测量方法开展工作。经试验确定采样粒级为-5~+20目;采样密度2个点/km2;采样介质为残坡积物或冲、洪积物。经4个1∶20万图幅的区域化探扫面工作,取得了明显的异常圈定和地质找矿效果,方法技术有效。

Element migration in soils is a complicated system which is irreversible-process,open-system and geochemical-coupling.The purpose of research is to open out complexity of element migration in soils.The studied area is located in high-cold lake marsh region of Qinghai province,including intermountain,mountain and lacustrine marshes.Soil horizon samples and grain-size samples in the three studied area were collected.Element concentration and chemical facies concentration were analyzed in the laboratory.From rock to topsoil there is a clear lowered tendency of element concentration.On the contrary,there is an elevatory tendency of element fractal calculated by concentration-frequence method.Facies fractal of element showed a complicated structure character in soils.The mechanical dispersion and chemical facies transition of elements and mechanics of fractal stretching in weathering process in high-cold lake marsh area have been achieved.

土壤中元素迁移是一种开放体系、远离平衡、多种作用耦合的复杂过程,文章用分形方法研究了元素迁移的复杂性特征。选择高寒湖沼景观3个微景观作为试验区,分别是山间沼泽、山地沼泽、湖泊沼泽,系统采集了土壤剖面样品和土壤粒级大样,分析了元素全量和相态。研究了土壤中元素全量和相态分布特征;用元素含量-频数分形方法计算了土壤层元素全量的分维,也计算了土壤粒级元素的相态分维;研究了元素迁移过程元素含量和分维的演化特征。研究表明,高寒湖沼景观土壤中元素地球化学迁移机理是机械分散和化学溶蚀作用,迁移机制具有分形伸展规律。
