Book excerpt: Excerpt from Memoirs of the Geological Survey of India, 1871, Vol. 7 And although less varied in their geological relations than those of other districts of smaller extent, they are not wanting in many points of interest to lead one to their examination. Numerous, however, as the observers have been, their labours were all confined to limited portions, and the vastness of the area which the Vindhyans occupy rendered it impossible for one geologist to co-ordinate with certainty his results with those of others in distant localities. Even now large tracts of country exist in India concerning which our knowledge is so scanty as to prevent our deciding whether the rocks there belong to this formation or not. As, however, the survey of the Vindhyans has now been in progress for some years, and it must still be long before the examination is complete, it has been thought advisable no longer to delay the publication of the results hitherto obtained. It is in the area now finished that the formation is typically displayed. It is to a certain extent independent; and the description of its geology is not likely to be seriously affected by the working out of the remaining districts. Before entering on this description, it may be useful to give a brief summary of what had been effected by our predecessors in the same field. Of these Captain Dangerfield seems to have been the first, but only a small section of his memoir refers to the Vindhyan area. He found that the northern part of Malwa is chiefly occupied by sandstones and sandstone-slates, and that these rocks, after passing round at a short distance south of Jowra, also extend down its western boundary. The sandstones are generally very fine grained, some varieties affording very valuable building stone. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
