THE CARBONIFEROUS SUCCESSION IN THE KIRKBY MALZEARD AREA, YORKSHIRE

Abstract
Summary: Beds described range from the Sabdenian (H) to the Halifaxian (G 2 ) stage. The sequence is thinner stage for stage than in the Bradford area, with the most marked attenuation in R 2 . A shelly siltstone in R 1 , the Ure Shell Bed, and its associated shales yield a fauna rich in brachiopods. Above the persistent Brimham Grits are fifty feet of measures with two Lingula bands, thought to be the sole representatives of R 2 . Measures in G 1 and G 2 , include the Gastrioceras cumbriense band and two beds with Lingula. Some eight square miles of country hitherto mapped as Millstone Grit are considered to be of Westphalian age.
