In this article , the author studied the problems , such as theory basis , test technique , data processing method , methods of geology confines partition , encountered in the application of xrf technique in big scale geological mapping 本文探讨了采用x射线荧光现场测量技术开展大比例尺地质填图的理论依据、测试技术、数据处理方法、地质界线划分方法等问题，在此基础上，建立了一套简便易行的现场x射线荧光测量填图工作方法。
The processing and graphical representation of aeroelectromagnetic data of over 30000 traverse kilometers demonstrate the effectiveness of the techniques , and the apparent resistivity images obtained reflect characteristics of shallow electric distrbution , thus providing new data for geological mapping 通过对3万多测线公里航空电磁数据的处理与图示，证明了方法的有效性，取得的视电阻率图像反映了各测区浅层电性分布特徵，为地质填图提供了新的数据。
Based on the study of the 1 : 50000 geological mapping and field survey in some places , the rock groups of proterozic alashan group that was mapped by 1 ? 200000 geological survey in 1978 may be correlated the neo - archean seertengshan group in middle inner mongolia , and the third bed of zhuzhongmaodao formation is actually a series of structural conglomerate 摘要通过巴彦诺日公地区1 / 5万地质填图和重点解剖研究，认为原1 / 20万区调中所划下元古界阿拉善群大部分岩石组合可与内蒙古中部地区色尔腾山岩群进行对比，且祖宗毛道组三段实际上是一套构造砾岩。
Sedimentological and provenance data from tuchengzi formation in nuyingzi - goujiadian basin provide information about the links between erosional unroofing of adjacent thrust sheets and deposition within the basin . through field mapping , measured sections , and sedimentological analysis , we arrived at the following conclusions : 1 通过野外填图、实测地层剖面及室内分析工作，取得了如下主要成果和认识： 1 、土城子组主要由一套分选性和磨圆度都很差的碳酸盐质砾岩构成。
Therefore , it is essential to evaluate the metallogenic potential of copper - gold of this area by conducting a systematical research on the regional magma - fluid - metallogenic system . a combinational method of regional fluid geology mapping combined with other methods under the instruction in the theory of " magma - fluid - metallogenic system " has been employed to find out the mineralization condition and potential including the size of distribution area of ore - forming fluid 所以，以“岩浆?流体?成矿系统”理论为指导，运用区域流体地质填图方法及其它手段相结合的综合研究方法，进行区域性的岩浆?流体?成矿系统研究，基本查明工作区的成矿条件及成矿流体的流域分布范围与规模，对该区金、铜等成矿潜力作出评价十分必要。
This method can be briefly summarized as follows : based on the reconstruction of the process of formation of related ore deposits and construction of metallogenic models , reconstruct some important ore - forming geological events and their evolution processes are reconstructed by tracing the tectono - deformation petrofacies in the ore sources series , study the distribution patterns of ore materials in a series of geological events and indicators and degrees of gradual ore material concentration and formation of ore deposits and further explore and direct evaluation of regional resource potentials , mapping and mineral exploration in ore deposit concentration areas 成矿地质事件评价方法，就是在恢复矿床形成过程并建立成矿模式的基础上，通过对矿源岩系的构造变形岩相形迹追索来恢复与成矿有重要意义的地质事件及其演化过程，研究在这一系列地质事件中成矿物质的分布规律和逐步富集成矿的标志及程度，并用以进一步探索、指导区域资源潜力评价和填图找矿的方法。
The results as follows : the theory used in this method is reliable , the xrf technique is advanced , the partition of geology confines is accuracy , it is feasible to use xrf technique in - suit in big - scale geological mapping , the xrf technique is a new , fast , high efficiency method in geological mapping and it can be used in more areas 上述地区的应用试验结果表明：本文所提出的现场x荧光填图方法理论基础可靠、仪器小巧轻便、方法简便易行、速度快、准确度满足要求，是一种值得推广应用的新的填图方法。
