The most easterly sample (178) at approximately 3 km. from the coast is sand, comparable to the well researched ‘Old Red Sands of Guangdong’ (Zheng and Wang, 1998). Samples were taken from road cuts, approximately 1.5m below the surface and grain size analysis was performed by dry sieving and wet hydrometer method. For location see Figure 1, and for sample characteristics see Supplementary table 1. The Hainan samples are generally redder and appear more weathered than those farther north.|

The foreground is not bedrock, but compacted loess, and the exposed section represents the summit of a loess hill approximately 30m high. Photo taken after rain, explaining darker tone of lower section.|
