Proceedings of the Fifth Symposium on Antarctic Meteorites



In the last few years, Antarctica has become an important source of meteorites, and the Japanese Symposia on Antarctic Meteorites have emerged as major outlets for data on these objects. The Proceedings volume from the fifth such symposium, held in February 1980, is therefore most welcome.

This volume, like its predecessors, deals almost solely with Antarctic meteorites (exceptions are a paper on synthetic chondrules and two papers on sheet silicates in the Murchison, CM, chondrite), stresses observation rather than interpretation and synthesis, and contains few contributions by non-Japanese authors. Its 26 papers cover a very wide range of subjects, from chondrites to ureilites, from sample recovery and weathering to magnetic properties (four papers), cosmogenic nuclides (three papers), and compressional wave velocities. Though few meteoriticists will find all papers equally interesting, there is something in the volume for everyone. Even nonspecialists should enjoy reading Nishio and Annexstad's discussion of ice flow and the role it played on concentrating meteorites in such happy hunting grounds as the Allan Hills and the Yamato Mountains.
