Charged-particle and micrometeorite impacts on the lunar surface.
Abstract
The main lines of the investigations reported in this paper are (1) experimental studies of anisotropies in the registration and development of charged-particle tracks in various types of crystals, and the effect of these on the interpretation of solar-flare and galactic cosmic ray record in lunar crystals; and (2) analysis of natural microcraters on lunar glasses with special reference to simulation experiments carried out with an electrostatic dust accelerator and to the fossil tracks present in the same lunar spherules. The latter studies indicate that impacts by iron and stone micrometeorites on lunar material can probably be distinguished on the basis of the morphology of natural craters. Evidence is also presented which suggests that the micrometeorite flux probably went down with time over an interval of about 10,000-100,000 yr during an unspecified epoch of lunar history.-
