"Esssays on the Study of Pegmatites" on PIG
Hello PIGs:
I have recently retired, and by my reckoning, with perfect timing. This gives me an opportunity to do more with the PIG web page, and here is what I will be doing: in my own works, I cite some of the same published sources over and over again. This is because they are so fundamentally important for their contributions to the understanding of pegmatites, or because they convey insights of the authors that helped to explain the course of their own investigations and provided direction for others. So, I will begin to post essays on these papers that have helped shaped my own views of the pegmatite-forming processes. I will try to explain what makes each publication worthy of a close read. The essays will be, more or less, in the chronological order of the publications themselves. Where possible, I will provide copies of the papers, pending approval of the publisher. Otherwise, some are available for purchase from on-line sources, and I will provide links to those sources when I can. The series of essays begins with:
Cameron, E.N., Jahns, R.H., McNair, A.H., and Page, L.R. (1949) Internal structure of granitic pegmatites. Economic Geology Monograph 2, 115 p.
Without credible argument to the contrary, this is the most important paper ever written on the geology of pegmatites. It is worthy of several individual essays, the first of which – an overview of the work – is on the PIG webpage now under the new heading “Essays on the Study of Pegmatites.”
I remind you that you are welcome to submit your own articles, photos, notices, and questions pertaining to pegmatites. These must be sent directly to me at my email address, which is now
dlondon1@memphis.edumailto:dlondon1@memphis.edu
I will vet them for content, and when ready send them to the office manager of the Mineralogical Society of America. The MSA will in turn assess the suitability for the website, and post approved submissions.

All sounds good, Dave! We'll look forward to reading your essays.
Congratulations on your retirement... I'm sure you'll still be working on many facets of pegmatite research.
Fact is, I'm retiring too, as of October 2 (9 days from now!). Which means that I need to switch my email address for the Peg group, from this USGS address to my personal one, pmodreski@aol.com. Not sure if I can do that online, or if you need to change it for me; in fact, I guess I should just log in to my account on the MSA site, and change my contact information there.
