PLATE 16. 
Ture Serra GERAL FROM MINAS IN THE TUBERAO VALLEY. 
The dim wall in the background is the escarpment of erosion formed by the 
Triassic trap sheets and the underlying sandstones, below which comes the 
Permian shales. The foreground, looking up the Tuberdo just east of the 
Lauro Miiller railway station is on the Permian plant-bearing shales. The 
coal mines at Minas occur at a higher level to the left of the view. According 
to Dr. I. C. White this wall from the top down presents the following section : — 
1. Eruptive rocks, mostly diabase, amygdaloidal and otherwise, 600 M. 
2. Massive grey and red sandstones and conglomerates with intruded sheets 
and dikes of diabase. 200 M. 
Red sandstones and shales, a massive red sandstone at the base resting with 
slight unconformity upon limestone, approximately 100 M. The rocks 
below are referred to in the accompanying text. Page 92.
