A crystalline axis is flanked on both sides by highly-inclined and much-altered sedimentary rocks, which probably include the entire series from the carboniferous to the cretaceous rocks, in some parts overlaid by nummulitic deposits.
"The South of France--East Half"
Charles Bertram Black
That solid cretaceous mass is but the remnants of the countless inhabitants of the old seas,-life changed into solid, hard rock; and even now, as the green grass and the sweet sainfoin spring up on the surface, feeding the flocks and herds that will soon in their turn feed mankind, earth is turning back again into life.
"A Cotswold Village"
J. Arthur Gibbs
The Athabasca here cuts through a cretaceous sandstone,-soft, yellowish, homogeneous.
