This volume investigates the mechanisms of planetary accretion and the earliest geological history of the Earth, specifically focusing on the formation of the moon. The editors, Horton E. Newsom and John R. W. D. Jones, compile research from 28 subject-matter experts to evaluate the Giant Impact model. The text synthesizes geochemical, geophysical, and astronomical data to construct a comprehensive framework for understanding the conditions of the early solar system and the subsequent development of the Earth's crust and mantle.

Experts recognize this volume as a significant reference for students and researchers in planetary geology. Readers frequently note the technical density of the prose, which assumes a foundational understanding of geological and astronomical principles.
