Cratering Rates, Dating: Argon/Argon, Spherules: Lunar
Scientific paper
One of the primary goals of the Apollo missions was to provide information about the crater production rate on the moon, and hence on the Earth. Before the Apollo missions relative ages of different surfaces could be calculated by comparing the number of craters of a given size on the different surfaces. By returning samples from different lunar surfaces for radiometric dating, it became possible to attach absolute ages to different surfaces and to re-construct the cratering history of the early solar system. Our primary goal is to provide data about the crater production rates within the last 3 Gyr, although the method we propose will determine relative rates only, not absolute rates. We will do this by 40Ar/39Ar dating glass spherules from random craters. Initially we will measure the ages of 30 to 40 lunar spherules; ultimately we would like to obtain the ages of several hundred to a thousand or more.
