466 R. A. DALY LITCHFIELDITE AND SODA-SYEXITES OF MAINE 



Locality A is on the road, 310 meters north of Spears Corner. One 

 considerable outcrop is in the middle of the road itself and another larger 

 one is in a field a few meters to the west. Both are probably parts of one 

 body, with total exposed length of 20 meters and exposed maximum width 

 of about 10 meters. The litchfieldite is clearly intrusive into the adjacent 

 schists, sending many tongues into them and inclosing shredded xenoliths 

 (figure 2). On the north, east, and south outcrops are abundant enough 

 to prove that the intrusive mass does not extend more than a few tens of 

 meters in anv of those directions. Its extension to the westward could

not be determined. The maximum width of the body from north to south 

 is less than 75 meters and is probably less than 25 meters. 



The outcrop at locality B measures 30 meters from east to west and 18 

 meters from north to south. Here no actual contact with the invaded 

 schists was seen, but mapping of the neighboring outcrops showed that 

 this mass of litchfieldite is less than 50 meters wide and probably less 

 than 125 meters long. The longer axis seems to be parallel to the bed- 

 ding and schistosity of the inclosing formation, which strikes north 45° 

 east, with steadily vertical dip. 



Both bodies are probably short, thick pods, injected along the planes 

 of the schists, though locally cross-cutting those planes. The concordance 

 of the intrusives with the older structures seems to be like that manifested 

 by the many quartz-pegmatite lenses of the region.
