In the valley at Frampton, about four miles from the 
Cotteswolds, and not more than 60 feet above the sea level, 
are two remarkable pits, of which the following is a general 
section :— 
GRAVEL AND SAND 
3ft. 6in. 
5ft. Oin. 
The gravel is composed of Oolite, and Marlstone, with some 
Fossils from both, but Lower Lias Gryphites are most abundant. 
In the clay pockets rounded bits of Quartz are met with of 
exactly the same kind as those found in the clayey seams of 
the Oolite quarries on the tops of the Cotteswolds. The clay 
I submitted to Professor Cuurcu, who informed me that it is 
“full of brown Hematite fragments and colourless granules of 
Quartz, the total per centage of Silica being 69 - 60.” 
The following analysis of the various Clays I have mentioned 
shew an average of about 68 per cent of Silica, already proving 
they are not of local Oolite origin, and I believe they are 
mostly derived from the denudations of the New Red Sunstone.

The close agreement of the quantity of Silica of the valley 
clays as shewn in the section at Frampton, and the Quartzite 
character of the Clay at Todenham, with the Clay of the Cottes- 
wolds, points to a common origin: and the Clays now in the 
valley, which I believe were once on the high ground, suggest 
a vast amount of denudation by land ice, snow, and rain of the 
escarpment, to bring it into its present position.
