Assise e, 

 its fossils. 



Assises of 

 Division 2. 



ASSISE e. The fossils of this assise are contained in greenish-gray- 

 sand, alternating with layers of lavender-gray clay. The sand is 

 mostly pellucid quartz, and there are diffused pale green particles and 

 films, which may be glauconite or some magnesian silicate. There are 

 also black grains and a few lumps of calcium phosphate. Some of the 

 fossils are fragmentary.

DIVISION 2. 151 feet. 

 Assise a consists of 



3 feet of gray fine-grained felsite-conglomerate and grit. 

 33 "" dark purplish gray feldspathic sandstone with some 



slate conglomerate. 



37 " same rock with beds of gray quartzite about the 

 middle. The fossils are in the lower half of the 

 assise. 



Assise b consists of 



57 feet dark purplish-gray feldspathic sandstone. Fossils are in 



the lower part of the assise. 

 Assise c consists of 21 feet of similar sandstones, with a bed of gray 



conglomerate holding pebbles of purplish-gray (and a few of red) 



felsite, with some of black flinty slate. Fossils at the top of the 



assise. 



Notes on the fossUs of Division 2. 



ASSISE a. Fossils are rare and poorly preserved in these coarse 

 beds. Only a Lingulella was seen. 



ASSISE b. In the sandstones of this assise are abundant grains of 

 non-kaolinized red feldspar. The rock is strongly cemented and has 

 some small calcite veins : the cement is partly calcareous, but there is 

 enough iron to give the rock a rusty-brown colour when weathered.
