Beginning in March 1964, the Apollo astronauts participated in a number of geology field trips designed, firstly, to introduce the astronaut corps to geologic concepts and, laterly, to give crews assigned to specific missions detailed training in the types of observations they might expect to make on the Moon.
The file linked below was supplied by Glen Swanson, historian at NASA Ôs Johnson Space Center. It comes from a "draft copy of a book that was never published entitled Science Training History of the Apollo Astronauts by William Phinney. Phinney worked under contract to JSC in the early 1990s to work on this book but the project ran out of money and never got beyond the first draft stage. Phinney was the former Chief of the Geology Branch at JSC as well as former Associate Curator for Lunar Samples."
The file contains appendices, entitled "Geology Field Exercises: Early Training" and "Geology Field Exercises for Apollo Missions".
