oriented Explanation: Check this sentence, Ailish: "Shape-controlling factors prevailed during growth, shown by parallelism of oriented internal features to outer boundaries, regardless of shape, from crystal centers to margins" (link 1). Layman me thinks that's the idea behind "oriented". Also, you're right with "alteration" and "outcrop" (link 2). Quite, you're very well oriented. Good luck with it, cheers :) Reference: http://www.campublic.co.uk/science/publications/JConfAbs/4/6... Reference: http://www.chamberofmines.bc.ca/prospecting_school/fld_trip.... |
