摘要
无人机对野外地质工作有促进作用,然而其在金矿区野外地质填图中应用仍待探索。位于西秦岭造山带的李坝金矿区,其典型的露天开采模式及周边区域地貌,为探索轻量级无人机在矿床野外地质填图中的应用提供了良好的天然场地。通过使用轻量级无人机对李坝金矿区进行从矿区全貌到中段剖面露头等尺度的航空遥感影像拍摄,结合地面野外工作,从宏观到微观尺度解译了李坝金矿床的蚀变分带及断裂,在进一步阐明地质特征的基础上,建立了无人机地质填图工作流程。该工作是无人机航拍技术在野外实践中的积极探索,可以极大地促进在地质填图过程中对区域地质信息的了解与解读。
Unmanned Aerial Vehicle(UAV)can improve outdoor geological mapping.However,applications of UAV in the investigations of gold districts remain to be explored.The Liba Gold District is located in the western Qinling orogenic belt.The typical open-pit gold district development pattern and the peripheral landscape are favorable natural fields to explore UAV application to outdoor deposit geological mapping.Here,lightweight UAV-based aerial photogrammetry was performed to get the photos in the degrees from the whole landscape of the mining district to the level profiling outcrop in the Liba Gold District.With the help of outdoor fieldwork,alteration zoning and faults in Liba Gold Deposit can be interpreted,both from the macro to micro scale.Based on the further explanation of the geological characteristics,a UAV geological mapping workflow is established.The work is an active exploration of UAV aerial photogrammetry application to outdoor practice and can greatly promote the understanding and interpretation of regio-nal geology during outdoor field mapping.
