STRUCTURAL DATA
PETROLOGIC DATA
Rock Number: 1
Footwall contact with chill margin. Transition upward through pyroxenite into anorthositic gabbro. Between pyroxenite and anorthositic gabbro is a zone of screens (?) of older grantitoids. Looks like some 30-50cm pegmatites may be younger and intrude gabbro but all is sheared and unclear.
Plagiocalse glomerocrysts cluster around inclusions. Anorthositic gabbro contains several cognate inclusions of chill margin.
