Summary:The papers in this volume represent 24 out of a total of 55 papers presented at a Symposium on Alkalic Rocks and Kimberlites held in April 1985, in Fayetteville, Arkansas. The most widely agreed conclusions are that: 1) alkali rocks are present in nearly every tectonic environment, 2) mantle metasomatism is important to their genesis, 3) there is little or no crustal involvement in their production and evolution, regardless of their setting. (Abstracts of each paper are included in this issue of Mineralogical Abstracts.) [R.A.H.]
