γ能谱测量方法是一种简便、有效、快速的间接找金的方法，不同类型的金矿其伽玛能谱特征并不相同。与深成脉岩活动有关的脉状金矿，具有明显的伽玛能谱Ｋ／Ｕ参数异常；与中浅成中酸性侵入杂岩体有关的金矿，具有Ｋ／Ｕ，Ｋ／Ｔｈ参数正异常；而与浅成超浅成偏碱性杂岩体有关的隐爆角砾岩型金矿，则具有一致的Ｕ，Ｔｈ，Ｋ及Ｆ参数正异常。本文介绍了在山东东部乳山地区及临沂西部地区，利用不同的伽玛能谱参数进行不同类型的金矿找矿，取得了良好的效果。
Gamma spectrometry is a simple, effective and rapid method to find gold. Different types of gold deposits have different characteristics of Gamma spectrum. The vein-type gold deposits associated with the deep-veined veins have obvious K / U parameter anomalies in gamma-ray; the gold deposits related to moderate-moderately acidic intrusive complex have K / U and K / Th parameters Positive anomalies; whereas the cryptoexplosive breccia type gold deposits associated with shallow-paired ultra-shallow alkaline complexes have consistent U, Th, K and F parameters. This paper describes the different types of gold ore prospecting using different gamma energy spectrum parameters in the Rushan area of eastern Shandong and the western area of Linyi, and achieved good results.
