Extract

The geology of Charnwood Forest appears to have been first systematically investigated by Professors Sedgwick, Whewell, and Airy in 1833. A very brief notice of their labours by C. Allsop, Esq., is appended to the history of Charnwood Forest by J. R. Potter, 1842, as is also a valuable and detailed memoir on the geology of the district, by J. B. Jukes, Esq.

page 112 note 1 The syenite of Mount Sorrel has yielded several minerals, amongst which may be mentioned Molybdenite (sulphuret of Molybdena), by no means of common occurrence in England. Associated with it, in the same quarry, occur copper and iron pyrites, the latter but sparingly distributed. These minerals appear to occupy definite planes, or points, in the syenite.—R. E. Geol. Mag., Vol. III., p. 525.Google Scholar

page 114 note 1 In the extensive syenite quarry at Markfield, a vein of compact calcite occurs of considerable extent; it has a red or pink tinge, and possesses throughout the welldefined rhombic cleavage. It has been proposed to use this for economical purposes, owing to the extent of the vein and its pure character.
