摘要
在典型隐伏热液铀矿上方进行的穿透性地球化学地气测量方法试验研究显示,针对捕集介质的选择,相对超纯液体捕集介质,聚氨酯泡塑在抗干扰能力、异常形式等方面更加突出。通过地气测量方法在矿体上方、含矿构造带上方出现了清晰的U及其成矿伴生元素的综合异常。地气测量方法作为穿透性地球化学勘查方法的一种,在热液型铀矿勘查中具有良好的应用前景。
Several experiments on the measurement method of deep-penetrating geochemical survey over the typical concealed hydrothermal uranium indicate that, the polyurethane foam is more prominent in anti-interference and outstanding abnormal forms compared to the ultra-pure liquid capture medium. Through the gas measurement, it is clear to see the U particles and the metallogenic anomaly in their associated elements above the ore body and the ore-bearing tectonic belt. As a kind of penetrating geochemical exploration method, the geogas prospecting method has a broad prospect in the exploration of hydrothermal uranium deposit in the future.
