The chief merit of Lehmann is his accurate description of the stratified rocks (Flötzgebirge). He distinguished thirty successive bands of rock in the stratified system of Ilfeld and Mansfeld, and set forth the geological structure of that district in an accompanying series of diagrams and sections. Many of the terms in his description of the Thuringian deposits were adopted by him from the miners, and have been retained in geological literature; for example, Zechstein or mine-stone, corresponding to the
Dyassic group in England; and rothes Todtliegendes (Rothliegende) or red underlayer, the unproductive basement beds below the ore-bearing, and the equivalent of the Lower Dyassic.[3].Lehmann died in Saint Petersburg from injuries caused by the explosion of a retort filled with arsenic
