Description Microcraters attributable to impact have been discovered on an Australasian microtektite from a core in the Central Indian Basin. The craters resemble lunar microcraters and those generated during impact experiments. The largest crater here, which has a welded promontory, is unique. The projectiles that produced the impacts defined varying trajectories and velocities, ranging from hypervelocity to low velocity (a few 10 m/s). The impacts took place while the microtektite was in flight at an elevated target temperature. This is the first observation of the microimpact phenomenon on a microtektite
