PROCEEDINGS OP GEOLOGICAL SOCIETIES.

Liverpool Geological Society. — Oct. 23rd, 1860. 

 The following papers were read : — 



" On Fulverites from the Red Crag of Suffolk." By Henry Duckworth, 

 Esq, F.R.G.S. and F.G.S. 



" On the Geology of the Neighbourhood of Shelve, Shropshire." By George 

 H. Morton, Esq, F.G.S. 



This paper was illustrated by sections; also by a large and interesting collection 

 of both upper and lower Silurian fossils collected in the district by the author 

 of the paper and several other members of the society. The longitudinal range 

 of hills present very high land to the east of Shelve. Reposing thereon ai e the 

 Stiper Stones, rugged hills of siliceous sandstone, dipping west-north-west, 

 the summits being about one thousand six hundred feet above the level of the 

 sea. These are considered to represent the Lingula flags of North Wales. 

 Small cavities are common in the hard sandstone, some of which Mr. Salter 

 considers to show traces of Lingulse. Annelide-burrows have also been observed. 

 Above these rocks, which are some three thousand feet thick, is a series of dark 

 slaty strata, containing the following fossils : — Didymograpsus geminus, Ogygia 

 Portlockii, JSgii?ia bhiodosa, Theca simplex, Cucidlela anglica, Redonia com- 

 planata, TAngula plumbea ; also one or two species of Orthoceras, and several 

 indistinct forms. These have been found in the lowest accessible strata, and 

 may be considered the earliest fossils in the district. The Llandeilo rocks, 

 above the Stiper Stones, are about fourteen thousand feet thick. The strata 

 dip sixty degrees and seventy degrees, and at smaller angles. Excepting in 

 particular beds, fossils are rarely to be found ; but in several places they occur 

 in profusion, such as Dictyonema sociale, Ogygia Burchii, Belleroplion pertur- 

 batus, all of common occurrence in the upper Llandeilo. Glyptocrinus basalis, 

 (McCoy,) has also been found associated with Trinucleus Lloydii, and Orthis 

 striatida, &c, high in the series at Meadon Town. Many of the Shelve fossils 

 are figured in the second edition of Siluria. 



The " Corndon," the highest isolated hill in the locality, is a great outburst 

 of trap rock. Beds of volcanic ashes several feet thick, are interspersed with 

 strata several feet thick, containing organic remains, at Marrington Dingle. 

 At Hope quarry, two miles from Shelve church, the upper (Silurian) Llandovery 

 rock is seen, reposing unconformably upon rounded bosses of trap and Llandeilo 

 rock. Near that place are high cliffs of contorted strata. The district is of 

 extreme interest to geologists ; for within a circular space of country some seven 

 miles across, so many geological phenomena are to be studied under great 

 advantages. 



Dec. 11, 1860. 



Thomas Urquhart, Esq, presented to the "Liverpool Free Museum," 

 through the medium of the society, a beautiful series of Devonshire fossils, 

 under the name of the "Pengelly Collection," many of the specimens having 

 been cut and polished in order to show their internal structure, Mr. Morton 

 made some remarks upon them, and on the geographical distribution of Devonian 

 fossils in Europe. 



The following paper was then read . — 



" On the Oolite beds of Yorkshire as compared with their equivalent deposits 

 in Wilts and Gloucestershire. By W. S. Horton, Esq. 



This communication was illustrated by a vertical section taken from Swindon 

 to Birdlip, and compared with one of the Yorkshire coast from Filey to Whitby, 

 also a horizontal one from Oxford to Shortover Hill. After a short description 

 of each bed, down to the cornbrash, reference was made to the extreme variation 

 exhibited by the succeeding strata, which were co-ordinated as follows : —
