Detailed investigations of the microimpact phenomena on Australasian microtektites from four samples in the Central Indian Basin reveal an array of features such as very low velocity captured droplets, welded projectiles, angular fragments and dust, craters generated by projectiles defining an oblique trajectory, high velocity `pitless' craters and the conventional hypervelocity craters with a well defined central pit, radial and concentric cracks - found commonly on lunar surface materials. The microimpacts are a consequence of interparticle collisions within the ejecta plume (as suggested by their chemistry ) subsequent to a major impact and therefore reveal processes inherent in an impact generated plume. All the impact phenomena observed here have taken place while the targets and projectiles were in flight and are therefore secondary impacts in lunar terms. However, some of the resultant features are analogous to lunar microcraters attributed to primary impacts by cosmic dust. Therefore, ballistic sedimentation on the moon is likely to contain plume collisional debris as well.
