勘查地球化学作为一种重要的勘查技术手段，近年来在矿产勘查工作中取得了显著成效。通过在华窑山一带开展1/5万水系沉积物测量工作，初步查明了研究区内元素地球化学特征，结合成矿地质背景及元素组合特征，圈定出综合异常5处。通过对地球化学异常进行查证，先后发现了华窑山钨矿点、大口子东山钨矿点和华窑山毒砂矿点，划分出3处找矿远景区，分别是华窑山北钨、金远景区，华窑山钨、金、砷多金属远景区，以及鱼脊山钨、金、锡多金属远景区。在综合分析成矿地质背景和成矿规律的基础上，结合近年来区域找矿新突破，提出了华窑山一带新的找矿方向和下一步工作建议。

As an important geological prospecting method，geochemical survey has been widely used in regional mineral prospect survey with its fast and efficient characteristics，and has achieved good geological prospecting results.At present，the main methods used include river sediment survey，soil survey，rock survey，etc.The southern belt of Beishan，Gansu Province，is an important metallogenic belt in the Beishan area of Gansu Province，belonging to the arid desert Gobi landscape area，with poor natural conditions and low degree of geological work.In the area，the development of river system is generally short，and the primary and secondary river systems are the main ones. The river sediment can well reflect the mineralization information in the catchment area. The 1∶50 000 stream sediment survey was carried out in the selected blocks in the research area，and the content information of 14 elements in the research area was obtained，such as Au，Ag，Cu，Pb，Zn，Co，Ni，Hg，Sb，As，Mo，W，Sn，Bi. The obtained geochemical data were processed in combination with the strata，structure，and distribution of magmatic rocks in the research area.The elements in the research area have obvious classification characteristics，in which Au，Ag，As，Sb，Hg are a group of medium-low temperature hydrothermal elements，Cu，Pb，Zn，Mo，Ni，Co are a group of medium-high temperature hydrothermal elements and basic elements in basic and ultrabasic rocks，which are related to hydrothermal activities and basic and ultrabasic dikes controlled by NW and NE trending fault structures in the research area.W，Sn and Bi are a group of high-temperature element combinations，representing W mineralization in the research area.According to the distribution characteristics of the elements and the geological background，five comprehensive anomalies were delineated in the research area，including two Class B1 anomalies，two Class B2 anomalies，and one Class C3 anomaly. Through the general inspection and key inspection of the anomalies，Huayaoshan tungsten deposit was found in the HS-3 anomaly，and Dakouzi Dongshan tungsten deposit and Huayaoshan toxic placer deposit were found in the HS-4 anomaly.In the research area，three prospecting prospects with tungsten ore as the main ore were divided.It shows that the measurement of stream sediment has good geological prospecting effect in the southern belt of Beishan，and provides basic data for further geological prospecting work in the research area. At the same time，combined with the geological prospecting results in the southern belt of Beishan in recent years，the authors comprehensively analyzed the metallogenic geological background，metallogenic environment，mineralization，and metallogenic law in the research area，and put forward new prospecting directions and suggestions for the next step，which has reference significance for carrying out mineral prospecting in the arid desert Gobi natural landscape area of Beishan in Gansu Province.
