| 摘 要： | 磷块岩矿床中磷与放射性元素铀之间存在着共生组合关系。这是应用航空伽玛能谱测量普查磷矿的前提。通过对6个已知磷块岩矿床的航空伽玛能谱特征场的分析，建立了应用航空伽玛能谱资料确定磷矿找矿靶区的评价准则，并对昆阳磷矿区和王家湾磷矿区外围未知地区作了初步评价，确定了Ｉ类找矿靶区5片，Ⅱ类找矿靶区3片。现已在找矿靶区内找到了磷矿床。

| Abstract: | An association relation occurs between the phosphor in phosphorite deposit and radioactive element uranium, that is the foundation for application of gamma-spectrometric survey to the prospecting of phosphor deposit.Based on the analysis of characteristic field of airborne gamma-spectrometry on 6 known phosphor deposits,evaluation criteria for determining the target areas of phosphor deposits have been set up,and they have been applied to the evaluation of unknown areas beyond the Kunyang and Wangjiawan phosphor ore districts. 5 first-grade target areas and 3 second-grade target areas have been selected. It is reported that some phosphor deposits have been found in delineated target areas. |
