REPORT OF THE GEOLOGICAL AND CHEMICAL 

 SECTION, 1887—88. 



Chairman— Horace T. Brown, F.G.S., F.I.C., &c. 



This Section of the Society has confined its labours chiefly to Geo- 

 logical field-work, and there have not been as yet any regular Sectional 

 Meetings for the purpose of discussing subjects of Geological or Chemical 

 interest. 



No Sectional Excursions were arranged for the Summer of 1887, but 

 two of the General Excursions were of special Geological interest, and 

 the Chairman of the Section issued the Notes which follow with the 

 Excursion notice. 



Several working Excursions were arranged for the Summer of 1888, 

 but owing partly to unforeseen obstacles, and in part to unfavourable 

 weather, these were abandoned, with the exception of one which took 

 place on May 12th, and had for its object an examination of several 

 sections at Boothorpe, Woodville, and Swadlincote. At Mr. Wragge's 

 clay pit there is an interesting exposure of the Permian Breccias and 

 Sandstones, which has been described in detail by the President (H. T. 

 Brown. Esq.,) in a Paper, which he read before the Society, on April 6th, 

 1888. 



The members had a very good opportunity of examining this inter- 

 esting Section, and of seeing the striking unconformity of the Breccias, 

 both to the over-lying Trias, and the underlying Coal Measures. 



The party was then conducted to another Section in the neighbour- 

 hood, which has been recently opened out by the Boothorpe Clay Works 

 Company. Here the Permians are to be seen resting on the Coal 

 Measure Clays which exhibit signs of great disturbance and slicken- 

 siding. It was pointed out that this disturbance was due to the close 

 proximity of the great Boothorpe Fault, and that whilst the great 

 dislocation which marks this line of fault must be of post-Carboniferous 

 and pre-Permian date, subsequent earth movements on a much smaller 

 scale must have taken place along the same line of fracture in past 

 Permian times. 



After a visit to the open working of the RafTeree Coal on the up- 

 throw side of the Boothorpe Fault, the party walked home along the 

 Burton high road, and examined en route the outliers of Bunter Conglom- 

 erate at Midway, and the Boulder Clay, near Moat Bank.
