Irradiation history of lunar cores and the development of the regolith.
Abstract
Detailed studies by the nuclear particle track method of lunar core sections 70009, 70008, 60007, 60010, and 60009 indicate that the irradiation and depositional histories of individual lunar cores vary greatly. The presence of layers a few cm thick which have remained largely undisturbed for periods ranging from 1 to 100 m.y. is a common feature although the development of the regolith usually proceeds through the accumulation of smaller increments of heavily irradiated material that do not result in distinct layers. Typical accumulation rates are on the order of 1 cm/m.y.
