Interpretations of the geological processes operating on Mars are based on our knowledge of processes occurring on Earth. This 2007 book presents contributions from leading planetary geologists to demonstrate the parallels and differences between these two planets, and will therefore be a key reference for students and researchers of planetary science.

Often thought of as a volcanically dominated planet, the last several decades of Mars exploration have revealed with increasing clarity the role of sedimentary processes on the Red Planet. Data from recent orbiters have highlighted the role of sedimentary processes throughout the geologic evolution of Mars by providing evidence that such processes are preserved in a rock record that spans a period of over four billion years.

Mars Geological Enigmas: From the Late Noachian Epoch to the Present Day presents outstanding questions on the geology of Mars and divergent viewpoints based on varying interpretations and analyses. The result is a robust and comprehensive discussion that provides opportunities for planetary scientists to develop their own opinions and ways forward. Each theme opens with an introduction that includes background on the topic and lays out questions to be addressed. Alternate perspectives are covered for each topic, including methods, observations, analyses, and in-depth discussion of the conclusions. Chapters within each theme reference each other to facilitate comparison and deeper understanding of divergent opinions. Offers a transchronological view of the geological history of Mars, addressing thematic questions from a broad temporal perspective Discusses outstanding questions on Mars from diverging perspectives Includes key questions and answers, as well as a look ahead to which puzzles remain to be solved

Planetary scientist and educator Ken Coles has teamed up with Ken Tanaka from the United States Geological Survey's Astrogeology team, and Phil Christensen, Principal Investigator of the Mars Odyssey orbiter's THEMIS science team, to produce this all-purpose reference atlas, The Atlas of Mars. Each of the thirty standard charts includes: a full-page color topographic map at 1:10,000,000 scale, a THEMIS daytime infrared map at the same scale with features labeled, a simplified geologic map of the corresponding area, and a section describing prominent features of interest. The Atlas is rounded out with extensive material on Mars' global characteristics, regional geography and geology, a glossary of terms, and an indexed gazetteer of up-to-date Martian feature names and nomenclature. This is an essential guide for a broad readership of academics, students, amateur astronomers, and space enthusiasts, replacing the NASA atlas from the 1970s.

The Volcanoes of Mars offers a clear, cohesive summary of Mars volcanology. It begins with an introduction to the geology and geography of the red planet and an overview of its volcanic history, and continues to discuss each distinct volcanic province, identifying the common and unique aspects of each region. Incorporating basic volcanological information and constraints on the regional geologic history derived from geologic mapping, the book also examines current constraints on the composition of the volcanic rocks as investigated by both orbiting spacecraft and rovers. In addition, it compares the features of Martian volcanoes to those seen on other volcanic bodies. Concluding with prospects for new knowledge to be gained from future Mars missions, this book brings researchers in volcanology and the study of Mars up to date on the latest findings in the study of volcanoes on Mars, allowing the reader to compare and contrast Martian volcanoes to volcanoes studied on Earth and throughout the Solar System. Presents clearly organized text and figures that will quickly allow the reader to find specific aspects of Martian volcanism Includes definitions of geological and volcanological terms throughout to aid interdisciplinary understanding Summarizes key results for each volcanic region of Mars and provides copious citations to the research literature to facilitate further discovery Synthesizes the most current data from multiple spacecraft missions, including the Mars Reconnaissance Orbiter, as well as geochemical data from Martian meteorites Utilizes published geologic mapping results to highlight the detailed knowledge that exists for each region

This text focuses on the environmental evolution of Mars. Particular emphasis is given to the understanding of Mars as a cold planet throughout its entire geological evolution, starting as a wet world where liquid water was abundant on the surface, albeit the low temperatures, and its sequential transition into a dry planet as temperatures turned even colder.
