This paper reports our studies of HASP glasses with an ion microprobe. Our studies of lunar volcanic glasses demonstrated that we can measure Li, Be, and B with great precision and accuracy. Brearley and Layne (1995) measured Li, Be, and B in chondrules and considered their volatile behavior. They found that Be is positively correlated with Al, showing that its behavior is strongly refractory and that Be is negatively correlated with the volatile LLE, B. We now want to see if these same systematics hold for HASP glasses which show a range of Al/Si ratios and have specifically targeted Apollo 14 impact glasses. The experimental design is to determine the behavior of elements with a variety of volatilities, with emphasis on the light lithophile elements (Li, Be, and B), the REE (La, Ce, Nd, Sm, Eu, Dy, Er, and Yb) and Sr, Y, and Zr.
