| 中文摘要: |
| 白杨河矿床的构造体系可分为接触带构造体系和走滑构造体系。接触带构造体系围绕花岗斑岩的边部发育,走滑构造体系发育于花岗斑岩北缘接触带部位。根据控矿特征,划分出成矿前走滑拉伸阶段、成矿期构造活动阶段和成矿后构造改造活动阶段,并分析了各阶段的断裂运动方式及成矿作用的产物。根据对白杨河矿床构造控铀体系及模式的分析,结合已发现铀矿体的空间展布特征和产状变化,圈定了下一步扩大铀资源量的3片重点找矿靶区,并描述了各靶区内的构造控矿特征。 |
| 英文摘要: |
| The tectonic system within Baiyanghe deposit is composed of contact zone structure system and slide structure system. The contact zone structure system distributed around the edge of granite porphyry, and the slide structure system distributed in the contact zone structure in the northern granite porphyry. According to the ore-controlling characteristics, metallogenic evolution stage is divided into pre-mineralization strike-slip stretching stage, the construction phase of metallogenic phase, post-mineralization tectonic reformation stage. The fault movement in different stages and the mineralization product were analyzed. According to the analysis of tectonic system and pattern of uranium deposit, in combination with the spatial distribution characteristic of uranium orebodies, three prospecting target areas for uranium orebody were delineated for the next stage exploration, and the structural ore-controlling features within each target area was described in detail. |
