Oct 24 Friday Andmrs
Started out at 8.30 for Bradford to see the Bradford chalk. It is a flint chalk interlarded with much blue-black thin zones of fine sand - long gaps that rather act as chalk.
We then went up Skelley Crags and saw the agulatum succession from the Greta-Dimpson-Hunter (Clinton- Heldwy shale- Upper Hunter li) and then the Durdfer chalk. Then followed a curved zone about 10 ft deep over the agulatum & came sandstone followed.
Then came in a series of blue to flint chalks with an occasional thin sandstone. About 110 ft down here for Buntay
a small Oengella fauna. Forty foot higher we get the Chrostyphia zone with many Orbitoides and Lenticulites
Then came a thin sandstone beneath which I saw for a form Phylidomella? (see the specimen)
The whole of the Crag above Durdfer is 1600 ft thick ascending to the first prominent sandstone 20 ft thick. Then come an unexposed zone followed immediately by the Penn- sylvanian. As this sandstone is like that of the Pennsylvania and oddly unlike that of the Crag are in the present drew the Tenn-Penn line at the bottom of this sandstone.
We then concluded to go on to Burngr and re-ex- amine the Crag 2 1/2 to 3 mile north of Burngr, the same place we saw on Oct 21st.
