PLATE 18. 



Augite porphyrite dike with numerous inclusions of sandstone, shale, and 

 fragments of vesicular lava, about six miles north of Lages on the road to 

 Corytibanos, Santa Catharina. 



The cutting edge of the palaeontological hammer points out a small block 

 of red sandstone. The upper long hunting knife point rests on a fragment of 

 included trap; the German army knife lower down points to a light colored 

 sandstone. View taken in a roadside wash-out, August 28, 1908. Page 95.
