金矿勘查中的伽玛能谱测量--以黑龙江乌拉嘎金矿外围柳树河区为例 总被引：1，自引：1，他引：0
金成矿受岩性、构造及蚀变控制,蚀变使含矿构造破碎带与围岩出现放射性差异,因此可应用伽玛能谱测量进行金矿勘查.为了提高黑龙江乌拉嘎金矿外围柳树河区的金矿勘查效果,利用伽玛能谱对该异常区进行了扫面测量.通过该项研究表明了含矿构造破碎带的存在及成矿流体中低温矿化的特点;在矿化带上方钾及总道显示高值异常,而铀道显示低值异常:证明应用该方法找金的有效性.需要指出的是,不同地区和不同类型矿床伽玛能谱的特征参数是不同的. 相似文献

A geochemical soil sampling survey undertaken at Tumallpalle uranium mineralized zone Cuddapah district, has confirmed the
presence of uranium anomalies in soils. Bulk soil samples were collected at every 20 m along the traverse from approximately
30 cm below the surface and were assayed for uranium by x-ray fluorescence (XRF) and inductively coupled plasma mass spectrometry
(ICP-MS). The uranium anomalies detected by the insitu radiometric survey show a correlation with the helium highs. The soil
gas helium studies have aided in delineating the subsurface extension of the deposit. This study endeavors for an integration
of different techniques in a known area which could probably aid in delineating uranium zones for optimal exploitation in
the future exploration programmes. 相似文献

Intensities and anomalies of radiometric (gamma) natural fields are related to structures in geologic sections. Positive and negative anomalies in the overburden of petroliferous as well as of "sterile" structures are essentially functions of lithologic and/or mineral composition of the rocks which, in turn, depend on tectonic structure of the area. These and still other complexities, suited as they may be for interpreting radiometric expressions of various structures, are still in need of further research. -- AGI Staff. 相似文献

The uranium mineral occurrence of Stolovac is located in the middle of a Permian red sandstone formation, the westernmost east‐Serbian Carpatho‐Balkan metallogenic province, or the Ridanj–Krepoljin ore zone. It was found by geological radiometry survey at the anomaly spots indicated by aerial gamma‐ray spectrometry (AGS). The task of anomaly identification is to accurately locate the AGS‐recorded anomalies in the field, to define the source of anomalous radioactivity (natural or artificial), to understand the relationship between the anomalous radioactivity and the given structural and geological situation, and to sample the material. The geological radiometry survey at scale 1:25,000 indicated increased radioactivity in gray sandstones of the Stolova?ki stream bed in Stolovac, some 40 km NE of Para?in. The instrument used was a scintillometer SSP 2NF, and the measured radioactivity was 10‐fold higher than the local background level. Of all the customary field work, the greatest volume (trenching, drilling and accessory testing) was carried out in Stolovac; other radioactivity anomalies in the red sandstone formation remained inadequately explored and are the subject of this paper. The 3‐year exploration in uranium at Stolovac indicated sandstone‐type infiltrated uranium mineralization in sandstones in the middle of the Permian red sandstone formation: a complex called “variegated rocks”. 相似文献
