The contributions of lunar microcrater studies to understand the overall micrometeoroid environment are summarized and compared to satellite data. In comparison with small-scale laboratory studies, most lunar crater morphologies are compatible only w

A computer model based on Monte Carlo techniques was developed to simulate the destruction of lunar rocks by 'catastrophic rupture' due to meteoroid impact. Energies necessary to accomplish catastrophic rupture were derived from laboratory experiment

Inclusions of granitic basement rocks, collected from the sparse ‘lava’ exposed at the 1.8-km-diameter Tenoumer crater, Mauritania, exhibit distinctive petrographic features considered indicative of shock-wave action and diagnostic for meteorite

Hornblende-rich concentrates from quartz–feldspar gneisses of the Grenville Province near Brent Ontario, have yielded K–Ar apparent ages of 1570 to 1480 ± 80 m.y., while coexisting biotite- and feldspar-rich separates give 'normal' Grenville K

Detailed optical stereomicroscope study of seven lunar rocks (12006, 12017, 12021, 12038, 12047, 12051, 12073) has been made. Common microcraters on crystalline rock surfaces consist of a central glass-lined ‘pit’ surrounded by a crush-zone or

An attempt to measure the relative times of formation of 25 microcraters on lunar rock 60015 is discussed which was carried out as part of a study of the flux of interplanetary dust and possible time variations of that flux over periods of 1000 to 1
