| 中文摘要: |
| 在覆盖区,常规填图方法填制的地质图,由于信息量少导致整体质量不高。钻探作为获取深部地质信息的最直接手段,可揭露第四系、控制基岩顶面埋深与起伏、验证推测模型、研究地质构造、圈定地质体间的重要接触关系,服务于覆盖区填图,同时,可对残积层、基岩芯(样)进行地球化学元素分析,直接指导找矿。本文总结了一套适用于内蒙古中东部荒漠草原浅覆盖区填图的钻探技术方法组合,为相似景观区区域地质调查和矿产调查提供技术支撑。 |

| In shallow overburden areas, the overall quality of conventional geological maping is poor due to the lacking of necessary information.As the most immediate way used to obtain deep geological information, drilling can provide service for geological mapping in overburden area through its ablities of explosing the Quaternary cover,controlling the depth and boundary of bury of bedrock, verifying the prediction modle and geological structure and delineating the important contact relation between geological bodies.Meanwhile, through drliing,geochemical analysis can be done on the samples and cores obtained from residual layer and bedrock, and the result of analysis will play a guiding role on further minerals exploration activities directly.A shallow drilling technology for geological mapping in the desert and vegetation-covered areas of Eastern Inner Mogolia has been presented in this paper which aims to provide technical support for regional geological survey and mineral resources exploration in areas with similar conditions. |
