Hiya.
I'm sure you will get useful information from your email, and hopefully offers of additional specimens, but I hope you have the two ring-binders for the Ward's Collection (original 1960s? in old black binder and revised 1978? In newer brown binder). These have locations, references, and "decent" petrographic descriptions.
The Pateca sample is even worse, of course. Only a few crumbs left after we made sections. I tried to get more, and even followed the trail to some of the original researchers, but nobody was quite sure of the outcrop. Jane Selverstone may be the most help if you still use the sections. On the other hand, the hand sample sucked. Just a brown blob with no discernible minerals to speak of. But what textures in section!

Subject: [geo-metamorphism] looking for lineated amphibolite schist
Hi all,
I have a teaching sample reputedly from "Elkin Peak" that is a black, fine- to medium-grained, lineated and foliated hornblende schist. It's a great teaching sample but one small piece among 20+ students in lab is just not working. Can anyone help me find/acquire more? I do not have any other location information. (Sample also has ~15% plag and quite a bit of titanite as well as quartz, zircon, apatite, biotite, and magnetite.) Any ideas?
Thank you,
