ering index is useful for ordinary chondrites. Three band strength ratio method utilizing the reflectance spectrum over the 1- m band is less subject to space weathering than the common BAR method in estimat-ing the olivine/pyroxene ratio of ordinary chondrites.

Introduction. A long-standing issue in planetary science is the connection between individual meteorites and their asteroidal parent bodies. Based on telescopic observation, one of the largest groups of asteroids (S-type) was found to have a mineralogy (low-calcium pyroxene and olivine) similar to that of the most common class of meteorites (80%, ordinary chondrites) 1
