Lootport as the former is a little flue shale that weathers not readily leaving the Lootport orthogneis in small projecting cliffs. The Archostin-Lootport contact is clearly a broken one. The evidence is lost in the physical side and is as much torn out by the fauna. Is the check of the Lootport here due to diagenetic changes? This is these beds that the springs come from. Also Dictyonema (?) amyiforms. The check is hardly due to weathering corrosion and is probably one due to diagenetic conditions derived largely from the springs. The Archostin shale is from 10-16 foot thick. It comes in suddenly as a shale above the very thin bed of Clinton and then the veins alternate between two beds of very fine grained dolomite and shale that more or less weather or looks like the Archostin at first, but is hardened with time. Fossils are practically absent in the upper 6 foot directly below them there is a zone of a few inches
