Ｕ的放射能和特性构成吉林夹皮沟金矿和海沟金铀矿主要成矿条件之一，它从另一侧面为大型、超大型金矿的形成探求一条新途径：（１）成矿背景效应：板块俯冲使幔源物质发生分熔形成含铀钾长花岗岩，随构造活动的进行Ｕ进一步富集，由Ｕ、Ｋ蜕变出α粒子组成一个巨大放射能量场；（２）加热释放效应：幔源基性脉、Ｃ－Ｈ－Ｏ流体和壳源中酸性脉、岩浆热液同时脉动性上侵；（３）富硅低钙效应：石英正长斑岩脉控矿；（４）辐射致色效应；（５）易溶稳定效应：Ｕ６＋易溶呈络离子；（６）有利载金效应：ＵＯ２２＋加入易形成黄铁矿；（７）选择沉淀效应：沥青铀矿沉淀同时易促使Ａｕ和多金属硫化物沉淀；（８）产状控制效应：因钾长花岗岩体形态、大小与金矿规模、产状具对应关系，所以探矿靶区应重点选定在钾长花岗岩体之内或之上的变质及沉积地质体中，石英正长斑岩脉可直接作为找矿标志 The radioactivity and characteristics of U constitute one of the main metallogenic conditions for the Jiapigou gold deposit and the Haigou gold uranium deposit in Jilin Province. It explores a new approach for the formation of large-scale and super-large gold deposits from the other side: (1) metallogenetic background Effect: Plate subduction causes mantle-derived materials to melt and form long granite containing uranium-bearing potassium, further enriched with U during tectonic activities, and α particles are transformed from U and K to form a huge radiation field. (2) Heated release effect: Mantle-derived basal veins, C-H-O fluids, and horizons in the crust; (3) silicon-rich and low-calcium effect: quartz positive porphyry vein control ore; (4) (6) Beneficial gold-bearing effect: UO22 + is easy to form pyrite; (7) Precipitation effect is selected: precipitation of pitch uranium deposits can promote the formation of Au And polymetallic sulphide precipitation; (8) Yield-controlling effect: Due to the relationship between the shape and size of the potash-bearing granite and the size and shape of the gold deposit, the prospecting target area should be mainly selected in the magmatism Modification and geologic deposition or above, the quartz porphyry syenite may be used directly as symbols for prospecting
