New GSA Special Paper takes us to the Moon
Boulder, CO, USA – Lunar missions over the past 15 years have brought to Earth data that is greatly improving geoscientistsí understanding of the stratigraphic features and characteristics of Earth's Moon. Missions targeting basins, highlands, mare deposits, and the lunar poles provide information to aid planetary geologists in piecing together, through maps and models, the nature of our closest neighbor.
Lunar stratigraphic relationships and issues relating to their resolution occur at a wide variety of scales — from the very largest (impact basins) to smaller scales (large impact craters, discrete highlands, and volcanic terrains), where detailed mapping of structural, volcanic, and impact-related features has increased understanding of three-dimensional lunar stratigraphic relationships in areas where the chronological history has been unknown or incomplete.
Editors William A. Ambrose of The University of Texas at Austinís Jackson School of Geoscience and David A. Williams of the University of Arizonaís School of Earth and Space Exploration have brought together 17 authors sharing the latest knowledge to help provide a complete picture as possible of the current status of the science.
Their investigations address several major questions regarding the Moon's origin and basin history, including (1) the lunar cataclysm hypothesis; (2) the timing and relative age of major basins such as South Pole-Aitken; (3) stratigraphic relationships of basins and mare-fill units within the South Pole-Aitken basin; (4) recognition of cryptic basins from recent topographic data, leading to a more comprehensive lunar stratigraphic sequence; (5) internal mare stratigraphy and history of emplacement of volcanic strata in major basins; and (6) understanding the formation of lunar sinuous rilles through analysis of their final morphology, providing insight into lunar volcanic processes and local stratigraphy.
