A collection of geological facts and practical observations, intended to elucidate the formation of the Ashby Coal-field. In the parish of Ashby-de-la-Zouch and the neighbouring district; being the result of forty years' esperience and research / By Edward Mammatt. Illustrated by a map and profiles, coloured sections of the stratification and one hundred and two plates of vegetable fossils, after drewings taken from nature, by Robert Ironmonger.
A privately printed local geological survey of the Ashby-de-la-Zouch coal-field, compiled by mining agent Edward Mammatt in 1834 with 102 plates of plant fossils drawn from specimens by Robert Ironmonger, aimed at coal proprietors and geologists. The lithographs show numbered rock fragments floating on blank paper, their irregular silhouettes filled with ribbed, striated and leaf-print textures useful as isolated organic shapes or pattern fills.
