Seite 79 - ... underlying drift exposed at the lowest part between the broken rock and the level of the railroad is about 7 feet. Unfortunately the character of the neighbouring surface is so much obscured, that it is difficult to estimate the lateral extent of this great mass of disturbed oolite, which, although so distinctly isolated, retains sufficient uniformity of character to lead us to infer that it has not been far removed from its original site.

Seite 75 - Hill in Sheet 70, is . more than 200 yards across and is composed of the Marlstone Rock-bed. It is noteworthy that these masses always belong to the rocks which form the highest ground, and, which in the glacial submergence would constitute the last points remaining above water.
Seite 81 - Jurassic detritus on the western slopes, the fact that enormous masses of raarlstone occur many miles to the eastward of the only place whence they can have been derived, the position of the large boulder of Cornbrash, near Ingoldsby, and the occurrence of Lower Lias Limestone at Croxton, 300 feet above its level, the steep slopes of the Oolitic escarpment up which the ice must have passed, the difficulties in the way of applying the prevalent land-ice hypothesis become considerable.
Seite 81 - It is obvious that the chalk fragments must have been brought from the north-east, the Carboniferous rocks can only have come from the north or north-west, and the marlstone blocks travelled in all probability from west or south-west of the places where they are now found When we consider the remarkable distribution of the stones and boulders in the clay of this area, the greater proportion of chalk detritus on the eastern slopes, and of Jurassic detritus on the western slopes, the fact that enormous...
Seite 116 - Many buildings constructed of a material similar to the oolite of Ancaster, such as Newark and Grantham Churches, and other edifices in various parts of Lincolnshire, have scarcely yielded to the effects of atmospheric influences.
Seite 75 - The transported masses of local rocks are sometimes of enormous size, especially in the northern portion of this area and in that to the south. The attention of geologists was first directed to these great transported masses by Professor Morris, who found that at the south end of the Stoke tunnel on the Great Northern Railway an enormous mass of the Lincolnshire Oolite limestone lay on undoubted Boulderclay.
Seite 116 - Church, built of an oolite from the neighbouring quarry, is in excellent condition, whilst the Abbey Church of Bath, constructed of the oolite in the vicinity of that city, has suffered much from decomposition ; as is also the case with the cathedral, and the churches of St.
Seite 75 - During the mapping by Messrs. Holloway, Skertchly, and myself, of the districts which I have indicated, we have found a number of such transported masses, some of them far exceeding in size that described by Professor Morris, and composed both of the Inferior Oolite and the Marlstone rock-bed.
