Overview

This book relates to many of the geological features of the Earth and Moon. It represents an update to the author’s book: The Twin Sister Planets Venus and Earth, published in 2015. The origin of the Earth’s Moon is one of the unsolved problems in the natural sciences. Although the investigators promoting the Giant Impact Model for the origin of the system claim to have solutions for some geological features of the Earth and Moon, much of their story is not consistent with the early history of these bodies. The time of capture is recorded in some detail on both the Earth and Moon at about 3.95 billion years before present and this date has not changed since 1977. The capture event/episode in this version of gravitational capture on Earth is the boundary between the Hadean Eon and the Archean Eon. On the Moon it is the time of the oldest mare basalts and also relates to the formation of a great circle pattern of large circular maria (Malcuit et al., 1975). This great circle pattern of large circular maria is a signature of close gravitational interaction between Luna (a name for the large planetoid before capture) and the Earth.

Author Information

Bob Malcuit earned his Bachelor and Master degrees in Geology from Kent State University in 1968 and 1970 and his Ph.D. in geology from Michigan State University in 1973.  He taught in the Geosciences Department at Denison University from 1972 to 1999.  His main research interests throughout his teaching career and in retirement are in the field of Planetary Science.  His first research article in 1975 was on a “great circle pattern of large circular maria” a pattern that he thought at the time was associated with a capture origin of the lunar body.  The place of origin of the lunar body was a mystery to Bob, as well as the other scientists that shared an interest in the capture model, until May 1999.
