空心微子区法在大兴安岭森林沼泽景观区区域化探异常圈定中的应用
Application of the hollow micro-area method for anomaly delineation in regional geochemical surveys within the forest swamp landscape area,Great Xing'an Range
摘要
Abstract
For regional geochemical surveys in the forest swamp landscape area,Great Xing'an Range,a variable main geological set-ting can lead to significant element background variations,posing challenges to anomaly extraction.After gridding the original data,this study compared the anomalies delineated by the commonly used anomaly threshold method with the anomalies obtained from the hollow micro-area method.The comparison reveals that the latter could effectively suppress the variations in the geochemical field caused by different geological settings,enabling more objective anomaly extraction.Based on a systematic summary of the area's geo-logical and geochemical characteristics,this study conducted anomaly screening and verification,achieving satisfactory prospecting re-sults.Finally,this study preliminarily summarized the dominant prospecting indicators and orientations for the area.关键词
