6122矿床(又称四号矿带)位于610矿田西部,邹家山-石洞断裂带的北东端,与622矿床相毗邻(图1)。是一个火山岩型铀钍混合矿床。矿床内地层简单、构造复杂、热液活动频繁。基底为震旦系千枚岩、石英云母片岩等浅变质岩系(Z),未出露地表。盖层为侏罗系上统打鼓顶组紫红色粉砂岩、砂砾岩(J_3d~1)和流纹英安岩(J_3d~2)以及鹅湖岭组晶屑玻屑凝灰岩(J_3e~1)和碎斑熔岩(J_3e~2)。碎斑熔岩
The 6122 deposit (also known as the No.4 ore belt) is located in the western part of the 610 orefield and the northeast end of the Zoujiashan-Shidong fault zone, adjacent to the 622 ore deposit (Figure 1). Is a volcanic uranium-thorium mixed deposit. The strata in the deposit are simple and complex in structure with frequent hydrothermal activities. The basement is Sinian phyllite, quartz mica schist and other super-metamorphic rocks (Z), not exposed to the surface. The caprocks are purplish-brown siltstone, conglomerate (J_3d ~ 1) and rhyolite diorite (J_3d ~ 2) of the Jurassic Upper Triassic, and the J3e ~ 1 and Crust lava (J_3e ~ 2). Debris lava
