| The investigation of metallogenic geological bodies,metallogenic structural surface and metallogenic characteristics was carried out in the area of huameiao,jiangxi province,to carry out research on key geological problems related to mineral resources and prospecting methods and technologies,it will provide resource support for the transition of declining resource city,Promoting the economic development and social stability of crisis mines and resource-based cities.Combined with geological data,this paper studies the application of comprehensive geophysical prospecting methods in ore prospecting and prediction in huameiao area.In order to obtain the information of stratum,rock mass,structure and mineralization from shallow to deep,this paper chooses the most effective combination of geophysical exploration methods based on the theory of geophysical methods.Combined inversion is carried out in combination with the gravity profile to infer the distribution of granite The metal mineralization anomalies in the shallow part were found by using IP Intermediate Gradient The deep granite interface and fracture distribution are determined by using CSAMT.The stratum,rock mass,geological bodies and tectonic features related to mineralization in the study area were comprehensively analyzed,and a mineralization model was established to provide theoretical basis for ore prospecting prediction in the region.Obtain the following main knowledge:1.Based on the fact that the huameiao deposit is a post-magmatic gasification-high temperature hydrothermal deposit,The deposit is controlled by rock mass and structure,The direction of prospecting is rock mass interface and structure.The quartz vein type tungsten deposit is the main type of the mine,and the direct prospecting is very difficult.The integrated geophysical prospecting method,which combines gravity,magnetic method,IP Intermediate Gradientand CSAMT,is an effective indirect prospecting method.2.The NNE-trending positive and negative magnetic anomaly associated with the cascade belt in the study area reflects the magmatic activity along the fault structure,which is caused by the intrusion of rock branches and dikes and their alteration.Through inversion and comprehensive analysis,the existence and location of deep concealed Ore deposit(deposit)are determined.3.The concealed state of granite and the location of ore bodies are determined by comprehensive geophysical prospecting and geological data analysis.The design of bore hole ZK2901 shows an industrial grade vein width of about 20m at 700m depth and a rock mass at 820m. |
