Figure 13. Site 1003 variations in the distribution of the subfractions within the coarse-grained sediment (>63 µm), which is subdivided into five component sizes. The solid grey tie lines indicate the positions of the even (glacial) isotope stages, and the broken grey tie lines indicate possible subdivisions of the stages. Both sets of tie lines connect the data to the isotope "age" model, which is based on the ¹⁸O data (the odd numbers represent the interglacials). The gaps in the record are not marked here so that the fluctuations in the graph can be seen clearly.
