Geology Comments

Dec 07, 2005 (C Papertzian) - On WHR (probably EHR or con 8) lot 35 there is a roadcut with garnetiferous feather amphibolite in a diorite dyke that cuts a marble. On EHR (8) lot 37 there is a feather amphibolite showing boudinage structure. As locations are vague these may actually be in the same roadcut - or at least very close along the highway. On con 9, lot 10 crosscutting garnetiferous feather amphibolite dykes are well-exposed and truncate marble at a low angle (1955).
