7. The (Lower?) Carboniferous Grits of Lye, in South Staffordshire. 
By W. Wicxuam Kina, F.G.S., and W. J. Lewis, B.Sc. 
In the ‘Geological Magazine,’ Dec. 4, Vol. ix. (1912), p. 437, we announced 
(inter alia) that purple beds of Lower Old Red Age existed at Saltwells. Since 
then we have ascertained that two miles to the south, at Lusbridge Brook, Lye, 
below the Thick Coal, Carboniferous Beds are exposed for a thickness of nearly 
400 feet as against about 200 feet at Saltwells. These basal beds are difficult to 
interpret. 
The succession below the Thick Coal in Lusbridge Brook is thus : (a2) Various 
Clays and Coals 280 feet; (4) Conglomerate 27 feet; (c) Red Clays (Plants) 
and White and Yellow Clays, in which are embedded many pieces of quite unworn 
pink calcareous Grits, and at base Limestone Grits and a Conglomerate, thickness 
40 feet; (d) White, Red and Yellow Clays. (d) is only exposed for about 30 feet. 
Total below Thick Coal 377 feet. Mr. F. G. Meachem has kindly given to us 
data proving that the beds down to the base of (b) are the same thickness in the 
Freehold Pit, Lye, and that there, below (b), they pierced Red Marls for 150 
feet. 
The interesting zones are those in which the Limestone and pink Grits occur. 
Broken fossils occur in the Limestone Grit, which is made up largely of angular 
pieces of Limestone. In the Conglomerate (6) a pebble 18 inches in diameter of 
highly calcareous grit containing Calamites varians has been found, which is 
probably another type of this Limestone Grit. A precisely similar calcareous 
grit was found in situ at or below (6) in the Freehold Pit, and above (c) a nearly 
similar type occurs in the form of gigantic slabs 25 feet thick in the Lye 
Cemetery. 
Encrinite débris only can be identified in the pink Grits. We found in the 
Clays (c) a minute fragment of a Brachiopoda with a straight hinge-line. 
Lithologically the Lye Grits are identical with the so-called millstone Grits of 
Titterstone Clee Hill (sixteen miles to S.W.), in which Lower Carboniferous 
plants occur; but until further evidence is found, Mr. Dixon suggests these 
Clee Grits be given a non-committal designation. At a later stage it was 
suggested to us that the Lye Grits may be the base of the Middle Carboniferous. 
In the Conglomerates there is distinct evidence of Inter-Carboniferous denuda- 
tion which removed in places, as at Saltwells, Coal Measure Ironstone (Newrop- 
teris), Coal Seams, Grey Limestones (Productus sp.?), and Limestone and Pink 
Grits. 
In ‘Q.J.G.S.,’ Vol. 55 (1899), p. 123, Mr. King showed that all the pebbles 
in the Permian Conglomerates of the Severn Basin are referable to a local 
source, except only those of Lower Carboniferous Age. The last-mentioned 
pebbles contain Syringopora and Caninia of probably D?-$ and Pendleside types. 
Some of the pebbles are identical lithologically with the Limestone and Pink 
Grits now found at Lye. 
In Permian times the Lower Carboniferous Rocks provided, from original 
and derivative local sources, much of the material in the Permian Calcareous 
Conglomerates. 
8. On some of the Basement Beds of the Great Oolite and the Crinoid 
Beds. By Epwin A. Watrorp, F.G.S. 
Sowerby, in Vol. 1 ‘Mineral Conchology,’ describes a brachiopod now known 
as Rhynchonella concinna. It is figured on T. lxxxiii. 6 from Aynhoe in North- 
amptonshire. A note of a quarry in the Great oolite made by the writer in 1883 
fixes probably the source of Sowerby’s shell— 
Aynhoe Allotments Quarry.
