Scientific paper

Laboratory impact experiments in the micron to millimeter projectile size range in silicate and metal targets have been performed in order to clarify the still ambiguously interpreted velocity dependence of the crater diameter to depth ratios (D/T). The experimental results clearly show the independence of the D/T ratio of velocities above a threshold velocity of 3-4 km/sec. The D/T ratio is a function of target properties and of projectile density. For a given target, the resulting approximate relation shows that D/T is exponentially dependent on projectile density, with the negative exponent varying between 1/2 and 1/5.
