TALCHEER GOAL FIELD

mucli the appearance of a tesselated pa-vement. (Fig. 5). Owing to 

 its almost invariable appearance at the surface of the ground, its presence 

 is always easily detected. 





Like many other beds of the Talcheer basin, from its nearly hoiizontal 

 position, it frequently covers a considerable area, although its thickness 

 never appears to exceed 200 feet. An obliquely measured section in a 

 nullah near Purongo seems to show that in that place it is about 200 

 feet ; here there are alternations of coarse and shaly sandstones, much
