Grande do Sul. Its association with granitic rocks leads to the inference 

 that it is to be looked for throughout the Archean area of Brazil. (Fran-

Coal, lignite, and peat. — The known coal deposits of Brazil are confined 

 to the States of Parana, Santa Catharina, and Eio Grande do Sul, where 

 it occurs in beds of lower Permian age. The mines have long been 

 worked in Santa Catharina and Rio Grande do Sul. In Minas lignites 

 are found in the Tertiary lake deposits. Lignite occurs over a wide area 

 in the Tertiary beds of the western part of Amazonas. See under 

 "Amazonas." Peat is known near Campos, in the State of Eio de Janeiro. 

 Brazilian coal is high in sulphur, but recent experiments show that it 

 can be successfully used on locomotives in pulverized form.* 



A full list of references to coal in Brazil is given at pages 287-300 of 

 I. C. White's Report on the Coal Measures and associated rocks of south 

 Brazil, published in English and Portuguese, xxviii -j- 617 pages, 4°, 

 illustrated, Eio de Janeiro, 1908.

Petroleum and oil shales. — Up to the present time petroleum has not 

 been found in paying quantities in Brazil. Petroliferous shales, however, 

 have been reported from Alagoas, Bahia, Ceara, Goyaz, Maranhao, Minas 

 Geraes, Parana, Santa Catharina, Sao Paulo, Rio de Janeiro, and Rio 

 Grande do Sul. They are found from the Permian to the Pliocene. The 

 most important papers thereon are those of —
