Notes: Comparison made to fresh rocks from the same unit where possible. Samples: 128/124 = 309-1256D-128R-1, 59–65 cm/309-1256D-124R-1, 60–63 cm. 122M/124 = 309-1256D-122R-1, 125–130 cm/309-1256D-124R-1, 60–63 cm. 140/138 = 309-1256D-140R-1, 74–79 cm/309-1256D-138R-1, 9–14 cm. 80/84 = 309-1256D-80R-1, 55–56 cm/309-1256D-84R-1, 54–58 cm. LOI = loss on ignition.
