It is probably the Barro Branco coal which occurs near the bed of 
Rio Cresciuma in the village of the same name where it was struck 
inthe well of Sr. Joio Targhetta, only 3 meters below the surface. 
It is also the one that has been exploited, 3 kilometers distant 
from Cresciuma, and used for smithing and other purposes in that 
village. Itis there only partially exposed along the bed of a small 
stream where.it showsas follows:

The upper portion of the Barro Branco bed is there concealed 
although its blossom is visible. 
About 15 centimeters of the top of n. 3, the lower bench of the coal 
is fairly good, and has been used for smithing purposes. 
In passing from Cresciuma south-westward to Ararangua, the Tu- 
bardo series dips below water level, and the Jraty black shale comes 
down, cropping along the road 10 to 12 kilometers distant from Cres- 
ciuma, and having been reported as coal at many points in the region. 
It is possibly this bad of black shale that has heen reported as coal 
near the town of Ararangua, since the rocks exposedin the hills there 
belong to the Passa Dois series above the Rio Tubarao beds. 
North-eastward from the Tubaréo region, no developments have 
been made on any of the coal of the series until in the vicinity of 
Quebra Dentes on the road between Florianopolis and Lages, about 60 
kilometers from Minas. There, about 4 kilometers from the 93rd kilo- 
meter post, acoal has been exploited on the fazenda of Messrs. Leonel 
Heliodoro da Luz and Fernando Gil Born, where at one of the strip- 
pings, the following succession is exposed :
