| Abstract: | Using the Shanxi Formation in the eastern Ordos Basin as an example, the authors employed several software programs to construct a 3-D model of lithofacies palaeogeography from 2-D lithofacies data. They also designed MATLAB algorithms to cut sections in different angles and multi-layer sections. This study helps to visualize lithofacies palaeogeographic maps and to facilitate space-time analysis of lithofacies data. It provides an efficient tool to study lithofacies palaeogeography. |
