Geological Map The accompanying geological sketch map shows a large area of limestone in the interior of Bahia. The limestones of the region, however, are not all represented on the map, and no attempt is made to show them in detail. This lack of detail is partly due to the scale of the map, which does not admit of it, and it is partly owing to the fact that their exact distribution has not been worked out over any considerable part of the region.
The geologic relations of the Bahia limestones to the other rocks of the State will be seen in the following tentative table of the general groups or divisions of the rocks:
