This report is written with the hope of stimulating new and further interaction between research scientists in the earth and the materials sciences. Workers in these fields often study the same natural phenomena and use similar instruments. The chief differences are the actual substances used in the experiments, and, sometimes, the questions that are being asked of nature. In qeneral, the earth scientist is studying the structure and coapoaition of natural materials to find out how the earth has been formed; the materials scientist is studying the structure and composition of both natural and processed materials so as to control their properties and behavior. The overall similarity of methods and instruments used suggests that frequent interchange between the two fields would be mutually profitable. Indeed, such interchange, when it has occurred, has been beneficial.
