Not illustrated. 1910 edition. Excerpt: ...fact that they occur on the eastern, or coastal, side of the outcrop of the Palaeozoic roe!.8 on which they have boen laid down. As in the other areas, thoy are associated at their base with the volcanic tuff, and are overlain also by a thick series of barren sandstone. The nature of the coal found, so far, is characteristic also of the same measures in other parts, and there appears to be no reason to conclude that the conditions of sedimentation differed to any great extent from those prevailing on the western side of the schists. Over the greater part of the area between the Palaeozoic rocks and Moreton Bay, and within the limits of this report, the paucity of outcrops renders the information obtainable from the surface scanty and indefinite, and gives to the mapping a corresponding amount of uncertainty. That the measures are, however, overlain by a considerable thickness of practically barren sandy strata is rendered certain by the Lindum Mere bore, and, more recently, by the bore at Toorbul Point, some distance north of the present map. In his Annual Progress Report for the year 1895, Dr. Jack gives the following record of the strata met with in a well sunk in portion 50, Parish of lingalpa (mistaken by him for portion 92). The well is sunk in a clay quarry, the property of Mr. Kelly, who gave Dr. Jack the information: --Ft. 111.
