The coal has been exploited to a small extent by surface strip- 
ping. 
Eastward from Treviso, there rises a high (300 meters) mountain 
of eruptive rock (diabase) known as Belvedere, and it separates the 
drainage of Rio Mée Luzia (which reaches the Atlantic through Rio 
Ararangua) from th? waters of Rio Urussanga which empties into the 
sea between Laguna andthe mouth of Rio Ararangua. In the summit 
of this mountain north from the church, coal is reported as present, 
but the only substance resembling coal that could be found isa dark 
bituminous shaly deposit greatly decomposed, along the bed of a 
small stream. It is possible that the eruption of the great mass of 
diabase may have lifted some blocks of the coal-bearing strata from the 
valley below to the summit of the mountain. 
Rio Carvao, a tributary of Rio Urussanga, rises on the eastern slope 
of Belvedere, and cuts down through the Barro Branco coal horizon, 8 
to 10 kilometers above the village of Urussanga. 
The following section is exposed at a water-fall over the massive 
sandstone above the coal just below the road leading from Belvedere to 
Urussanga :
