Abstract

Plagioclase and clinopyroxene form subhedral, unaltered grains amongst a background of finer-grained, intermingled iddingsite and zeolites. Iddingsite may be a pseudomorph after biotite. Described by Western Minerals Inc. as an 'interstitial ferrotholeiite, very highly fractionated…textures are similar to those associated with rapidly frozen or highly viscous melts.'
