WOODWORTH: GEOLOGICAL EXPEDITION TO BRAZIL AND CHILE. 695 
Signor Cicero de Campos (1908, p. 3) of the Brazilian Geological 
Service states that between the port of the Indias and Salto-Maua in 
Parana there outcrops a little below the falls on the left bank of the 
Rio Tibagy a vellow sandstone with enormous blocks of pink porphyry 
granite and of porphyry. The fall is caused by basalt. Campos 
refers the strata of the hilltops to the Carboniferous (Permian?). 
Near the sixty kilometer post on the railway from Ponta Grossa to 
Porto da Unido I noted an exposure of the compact yellowish beds 
which appear to be the weathered phase of the tillite as at Conchas. 
A large boulder was also seen in a cut a short distance north of this 
locality. 
Boulders and Pebble Beds near Palmeira.— On the divide south of 
Palmeira yellowish compact beds with blackened joints exhibit a few 
pebbles north of the 133 km. post. These beds continue in the railway 
cuts to and somewhat beyond the 130 km. post, then laminated yellow 
beds come in and a boulder about three feet (1 meter) in diameter 
appears onthe surface west of the track near a house north of 128 km. 
post, about eleven kms. north of Restinga Secca Station. Large 
blocks appear in a cut between 122 and 121 km. posts, north of branch 
road to Amazonas. Beyond 105 km. post, pink pebbly beds are 
intersected by the railway in the long descent, with tilted pebble 
bearing beds near 103 km. post. Tilted beds also occur near the 
ninety-nine km. post, possibly faulted beds. Tamandué4 Station is 
at the ninety-three km. post. Beyond this Station pebbles occur in 
sandstone at eighty-five km. post; again at eighty-three km. post. 
At seventy-eight km. post there is a good pebble bed and north of . 
seventy-six kms. gravels appear in a cut. 
The Glacial Conglomerate at Serrinha.— At Serrinha in the gorge of 
the Iguassti, where that river has cut deeply into the sandstones at 
the southern limits of the sandstone cuesta locally known as the 
Serrinha (little serra), there is a good exposure of beds, the general 
characters of which are shown in the annexed unmeasured section, 
(Fig. 16). . 
There is here east and west of the railroad station an exposure of 
small pebbled conglomerate rising about twenty-five feet above the 
level of the track. Quartz pebbles either angular or well rounded occur 
in this bed, with occasional pebbles of gneiss and possibly granite, 
together with quadrangular fragments of a now reddish friable sand- 
stone, presumably a rock derived from underlying beds. East of the 
station between the 69th and 70th kilometer posts, Dr. Euzebio 
Oliveira found in the conglomerate beneath the sandstones a dis-
