摘要: 寻找构造带对于矿产勘查具有积极意义, 对构造的含矿性进行判别, 尤其对于野外地表露头无矿化显示及隐伏构造的含矿性更为关键.为了对构造的含矿性进行快速识别, 采用X荧光测量方法、α杯测氡方法、地气测量方法等现场方法及不同方法技术的配合进行了金矿含矿与无矿构造的识别研究.川西北阿西金矿及石棉田湾金矿的试验结果表明, 上述方法技术及其组合可以有效地判别金矿含矿和无矿构造.Abstract: Tectonics is not only the main channel of ore-forming fluid transferring, but also the place where mineralizing elements are precipitated. Therefore, the searching for the structure belt is very important for mineral exploration. But not all structures contain minerals, so it is necessary to identify whether the structure contains mineral or not, especially those structures with no mineralization marker and with blinding mineralization. To attain the above goal, we have made some related identification research with XRF, geogas prospecting, and Radon detection methods. The test on Axi gold deposit and Tianwan gold deposit in Sichuan Province shows the validity of above method in distinguishing whether the structure contains minerals or not.
