194 TUE MAltQUETTE lEOXBEAEING DISTRICT. 



Although more abundant in this portion of the southern area than 

 elsewhere, the hornblendic and micaceous schists are not contined to it. 

 Small exposures of them are found scattered among the granite knobs 

 as far east as the east line of sec. 34, T. 47 N., R. 26 W. (Atlas Sheet 

 XXXV), and as far west as Republic (Atlas Sheet XI), forming almost as 

 great a proportion of tlie rocks in this ^^cinity as they do in the neiglil)or- 

 hood of Cliampion. In the interior of the area they are jn-obabh- also quite 

 common. Wherever found, most of the schists are more or less detinitely 

 banded and always distinctly foliated. The general direction of their 

 banding varies in its strike from north to northeast, and in its dip from 45° 

 northwest or west to as much southeast or east. Usually the dips are very 

 steep, and often they are perpendicular. 



Occup-snng less extended areas are the other foliated rocks of the 

 Southern Complex. These are the greenstone-schists and tlie various 

 gneisses. The former occupy a distinct but very small area near the shore 

 of Lake Superior (Atlas Sheet XXXIX), where they ])resent the same 

 featm-es as some of the corresponding rocks in the Xorthern Comjdex. 

 Their foliation strikes about east and west, and their dip is nearly vertical. 

 Occasionallv similar schists are found in other parts -of the southern area, 

 interspersed among the other rocks. Under these conditions they appear to 

 be mainly schistose dikes. 



The gneissoid granites are more common in the western ]X)rtif)n of the 

 Southern Complex than in its eastern portion, though they are found also in 

 the latter area. Their distribution is quite uniform throughout the granite, 

 but their abundance is inconsiderable when comjiared with their abundance 

 in the Northern Complex. Xo definite relations as to distribution have 

 been determined to exist between these gneisses and the massive granite. 



The Palmer gneisses are found only along the southern side of the 

 Marquette svncline. Their general distribution is indicated on the map 

 (Atlas Sheet IV). Further reference to them and to tlie gneisses is deferred 

 until the granites are discussed. 



From the statements already made it is e\'ident that cm" information 

 concerning the distribution and relations of the schists of the Southern 

 Complex is very incomplete. So little detailed work has been done in
