Excerpt from The Economic Geology of the Central Coal-Field of Scotland, DescriptionCarboniferous Limestone Series. Calciferous Sandstone Series.The Calciferous Sandstone Series is divided in the map into lavas (whinstone) and overlying sediments. Similarly the Coal Measures are divided into Productive Measures, and the overlying Barren or Red Measures.The lava ¿ows of Calciferous Sandstone age are the Oldest rocks exposed in the area. They form part of the Cathkin Hills, which may be regarded as an elevated fault-block, Since it is bounded on almost every side by faults.The Carboniferous Limestone Series is subdivided into three groups, not shown separately on the Index Map, viz.Upper Limestone Group. Limestone Coal Group. Lower Limestone Group.These will be shown by separate colours on one-inch sheets 23 and 31 which still remain to be published. In the same way the Productive Coal Measures have been divided into two subordinate groups, the line of division being the Splint Coal. This subdivision has been shown by difference of colour in the geological one-inch map of the Glasgow District.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
