11 11.51 m |
Second recessive section | ||
12 12 m |
S/D: 152/34NW -slitstone due to grain size -when hammered the rock chips off like shale -plant trace fossils -blocky and fizzes when HCL is added -bedding planes are visible with jointing and fractures -highly weathered compared to unit 10 |
||
13 1.2 m |
S/D: 153/40NW -trace fossils -platy and fissile |
||
14 1.5 m |
S/D: 153/40 -grass vegetation on most surfaces -an erosional or rock/mud slide may have been occurred(some recessive areas) |
||
15 3.2 m |
S/D: 150/40 -shale in blocky pieces -large volume of mudstone(slilt?) -softer shale -most likely siltstone (changed in depositional environment) |
||
16 7.5 m |
S/D: 150/42 -interbeded with shale(evident by the patterns of weathering/colour) -composition of layers in this unit sightly changes from NE to West (right to left) -some large blocks of rocks appeared for the first time(compared to the previous lower numbered units) -thickness of the beds has increased to about 30 m |
||
17 5.63 m |

18 7.5 m |
S/D: 147/41 -largely covered with grass and vegetation –any other data??? |
||
19 6 m |
S/D: 147/42 -a lot of shale; not much silt -interbeded with thin layers of siltstone -the middle parts of the bed is covered with vegetation(may have been due to an erosional and/or land/rock/mud slide events) |
||
20 9.75 m |
S/D: 150/40 -blocky and massive -shale with yellowish weathering colour -about 30% lamination on slit layers |

Second recessive section | ||
23 4 m |
S/D: 145/40 -mostly shale with heavily weathered surfaces -flakey |
||
24 6.3 m |
S/D: 160/40 -most parts are covered with vegetation(may be due to erosional and/or mud/rock slide events) -more siltstone |

Third recessive section | ||
26 15.56 m |
Pylons recessive section | ||
27 5.51 m |
S/D: 158/45 -trace fossils in the clay-rich areas -platy clay-reach slitstone -dark grey layers forming bands in about 5% of the unit(chert layers-did not reacted with HCL and chert nodules also found) |
||
28 4.7 m |
S/D: 155/42 -layered and platy -chert layer has disappeared(compared to unit 27) -calcite has recrystallized on the surface -distinct weathering patterns |
||
29 10.5 m |
S/D: 155/40 -siltstone -fracture patterns has changed compared to the units above(less random; more uniform fractures) -medium bed thickness with some lamination -fractures are mostly thin straight lines -less black minerals than unit 27 and 28 |
||
30 14.75 m |
S/D: 160/41 -thin curved fractures -when hammered, the rock breaks into smaller, thinner and platy pieces -reacted with HCL(fizzes) -carbonate rock and most likely siltstone -rounded corners can be seen on grains -rusting was observed for the first time(red-yellow weathering colour) -presence of pyrite and metalic minerals may be the cause of these “rust” weathering patterns -stiltstone |
||
31 13 m |
S/D: 160/40 -trace fossils(shiolthes/p?) -cryonide/brachiopod body fossils -ammonites and gastropods -cross cutting planes; softer beds -fizzes when HCL was introduced -yellowish weathering -wackstone(large % of grains) -calcium carbonates with body fossils -gradual contact between cross cuttings(grey bandings) |
||
32 4 m |
S/D: 160/40 -calcareous limestone(but almost a boundstone) -easily broken; platy and thin; aka not blocky -in situ growth of fossils; brachiopods(not fossils transported from the original deposition) -calcite nodules YOUNGEST unit |
