WOODBURN GLEN. 



The Geological Section of the Club visited Woodburn Glen 

 on Saturday, 25th September, to investigate a section of Creta- 

 ceous rocks exposed at the Woodburn River, Mr. Robert Bell 

 kindly acting as field conductor. 



There was a large attendance of members, and the party pro- 

 ceeded by the 1-50 p.m. train to Trooper's Lane; whence a walk of 

 about an hour brought them to the entrance of Woodburn Glen. 

 To reach the section the bed of the stream had to be taken in 

 several places, and the unusual amount of water at the present 

 season added to the difficulties. The beds examined for fossils 

 were Professor Tate's " Chloritic Sandstones " and " Glauconitic 

 Sands." A large number of fossils were obtained from an 

 exposure of the former in the east bank of the river. These 

 included Rhynchonella robusta, Ventriculites gibosus, Etheridgia 

 mirabilis, Inoceramus crispi, Ostrea semiplana, Terebratula carnea f 

 T. semiglobosa, and Pecten cequicostatus. A piece of chert was 

 also found. The "Glauconitic Sands," recognised by their deep 

 green colour, are well exposed in the west bank of the river, but 

 the water was so deep they were inaccessible to most of the party. 

 One member, however, waded across, and obtained specimens of 

 Exogyra conica, the most characteristic fossil of the zone. The 

 " Yellow Sandstones " were observed above the " Glauconitic 

 Sands," but were in an inaccessible position. A little higher up, 

 on the west side of the river, between the greensand outcrop and 

 the waterfall, a basalt dyke was noted traversing the chalk, which 

 in its vicinity was converted into marble, some specimens showing 

 a beautifully banded structure. 



The Geological Section of the Club had a most interesting 

 excursion to the Moira district on 9th October. A large number 

 of members, conducted by Mr. Robert Bell, started by the 1-50
