Book Description
This thesis was conducted in the framework of the German Research Foundation’s priority program Mars and the Terrestrial Planets as part of the project Chronostratigraphy of Mars. All global stratigraphic and geologic systems for Mars have been based on remote sensing data gathered during the Mariner 9 and Viking mission (Tanaka, 1986; Tanaka et al., 1992a), culminating in three 1:15M–scale geologic maps by Scott and Tanaka (1986); Greeley and Guest (1987); Tanaka and Scott (1987). Generally, most of the surface–forming processes were placed in the early phase of the Martian evolution. Chrono–stratigraphic schemes for Mars are derived from imagery and crater frequencies observed during Mariner 9 and Viking missions, and however, led to a wide range of chronologic systems with no clear consensus on the absolute ages (Hartmann, 1973b; Soderblom et al., 1974; Neukum and Wise, 1976; Hartmann et al., 1981; Neukum and Hiller, 1981; Neukum, 1983; Strom et al., 1992). Missions launched in the late 1990ies, such as Mars Global Surveyor and Mars Odyssey revealed very young volcanic surfaces, correlating in age with Martian meteorite crystallization ages (Hartmann, 1999a). Additionally, global topography (Smith et al., 1999a,b, Mars Orbiter Laser Altimeter) and gravity data (Zuber et al., 2000) as well as the discovery of strong remnant magnetization of the older Martian crust (Acu˜na et al., 1999), implied a more continual and diverse evolution than previously thought.

Book Description
Mars is about one-eighth the mass of the Earth and it may provide an analogue of what the Earth was like when it was at such an early stage of accretion. The fur ther growth of the Earth was sustained by major collisions with planetesimals and planets such as that which resulted in the formation ofthe Earth's moon (Hartmann and Davis, 1975; Cameron and Ward, 1976; Wetherill, 1986; Cameron and Benz, 1991). This late accretionary history, which lasted more than 50 Myr in the case of the Earth (Halliday, 2000a, b), appears to have been shorter and less catastrophic in the case of Mars (Harper et ai. , 1995; Lee and Halliday, 1997). In this article we review the basic differences between the bulk composition of Mars and the Earth and the manner in which this plays into our understanding of the timing and mechanisms of accretion and core formation. We highlight some of the evidence for early cessation of major collisional growth on Mars. Finally, we reevaluate the isotopic evidence that Mars differentiated quickly. Fundamental differences between the composition of Mars and that of other terrestrial planets are apparent from the planet's slightly lower density and from the compositions of Martian meteorites. The low density is partially explicable if there is a greater proportion of more volatile elements.

Book Description
The Geologic Time Scale 2012, winner of a 2012 PROSE Award Honorable Mention for Best Multi-volume Reference in Science from the Association of American Publishers, is the framework for deciphering the history of our planet Earth. The authors have been at the forefront of chronostratigraphic research and initiatives to create an international geologic time scale for many years, and the charts in this book present the most up-to-date, international standard, as ratified by the International Commission on Stratigraphy and the International Union of Geological Sciences. This 2012 geologic time scale is an enhanced, improved and expanded version of the GTS2004, including chapters on planetary scales, the Cryogenian-Ediacaran periods/systems, a prehistory scale of human development, a survey of sequence stratigraphy, and an extensive compilation of stable-isotope chemostratigraphy. This book is an essential reference for all geoscientists, including researchers, students, and petroleum and mining professionals. The presentation is non-technical and illustrated with numerous colour charts, maps and photographs. The book also includes a detachable wall chart of the complete time scale for use as a handy reference in the office, laboratory or field. The most detailed international geologic time scale available that contextualizes information in one single reference for quick desktop access Gives insights in the construction, strengths, and limitations of the geological time scale that greatly enhances its function and its utility Aids understanding by combining with the mathematical and statistical methods to scaled composites of global succession of events Meets the needs of a range of users at various points in the workflow (researchers extracting linear time from rock records, students recognizing the geologic stage by their content)

Book Description
This book's main themes focus on the environmental evolution of Mars and the exploration of the planet. 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. The evolution of the environmental conditions is regarded as a determinant for the emergence and maintenance of life. The book will give insights into the evolution of a variety of landscapes relating to the geological development of Mars, and their potential to harbor life, including the analysis of relevant terrestrial analogs in Antarctica. Also discussed is the cold hydrogeological evolution of Mars as recorded in the types and sequence of deposition of the aqueous minerals existing in the surface and subsurface of the planet.

Book Description
Asteroid science is a fundamental topic in planetary science and is key to furthering our understanding of planetary formation and the evolution of the Solar System. Ground-based observations and missions have provided a wealth of new data in recent years, and forthcoming missions promise further exciting results. This accessible book presents a comprehensive introduction to asteroid science, summarising the astronomical and geological characteristics of asteroids. The interdisciplinary nature of asteroid science is reflected in the broad range of topics covered, including asteroid and meteorite classification, chemical and physical properties of asteroids, observational techniques, cratering, and the discovery of asteroids and how they are named. Other chapters discuss past, present and future space missions and the threat that these bodies pose for Earth. Based on an upper-level course on asteroids and meteorites taught by the author, this book is ideal for students, researchers and professional scientists looking for an overview of asteroid science.
