Figure 20 Photographs showing Springfield Coal “split” by massive siltstone in the Millennium Mine. The lower view is a close-up of the upper view. Notice the ragged splaying of coal layers into the siltstone from both above and below, with one coal stringer crossing diagonally from the lower to the upper coal “bench.” Combined with the absence of roots beneath the upper “bench,” such geometry implies that the upper part of the peat deposit was rafted.
