Abstract
In northwestern Germany most natural gas deposits have been sourced by coalification gases derived from the coal-bearing Upper Carboniferous. This is the reason why a new coalification map for the top surface of the Carboniferous (1:500 000) is presented as a supplement and revision of a former map published in 1979 by the same authors. 130 new measurements of vitrinite reflectance (% Rm) from 72 deep boreholes and 60 outcrops have been introduced into the new map. Recent data on the stratigraphy of the top surface of the Carboniferous and its depth below the Permian, Mesozoic and Cainozoic cover, as well as new gas fields (found since 1978) have likewise been incorporated.Keywords
