摘要
In this paper using Q-type clustering analysis and R-type clustering analysis, coupled with the independent system’s ZTR maps, allow robust identification of specific directions of sediment source in each depositional stage. The result shows that there are four distinct sediment sources in the submember in the study area. These are the northwest source, the southwest source, the northeast source, and the east source. The directions of different sediment sources identified are in accordance with the main building directions of fans delta or alluvial fans. Using heavy mineral suites generated from cluster analysis to identify source area in the Weixinan Depression is quite effective. hemas-microsoft-com:office:office" />
