Martian Gullies and their Earth Analogues (2019; Geological Society of London Special Publication)
Edited by S.J. Conway, J.L. Carrivick, P.A. Carling, T. de Haas and T.N. Harrison
Gullies on Mars resemble terrestrial gullies involved in the transport of abundant material down steep slopes by liquid water. However, liquid water should not be stable at the Martian surface. The articles in this volume present the two main opposing theories for Martian gully formation: climate-driven melting of surficial water-ice deposits and seasonal dry-ice sublimation. The evidence presented ranges from remote-sensing observations, to experimental simulations, to comparison with Earth analogues. The opposing hypotheses imply either that Mars has been unusually wet in the last few million years or that it has remained a cold dry desert – both with profound implications for understanding the water budget of Mars and its habitability. The debate questions the limits of remote-sensing data and how we interpret active processes on extra-terrestrial planetary surfaces, even beyond those on Mars, as summarized by the review paper at the beginning of the book.

Encyclopedia of Planetary Landforms (2015)
Edited by Henrik Hargitai and Ákos Kereszturi
This encyclopedia provides a snapshot of our current geological knowledge on solid-surface Solar System bodies. Each entry contains information about the features’ morphology, its interpretation, proposed formation models, distribution and occurrence, planetary or terrestrial analogs, and research history. The entries are fully referenced. All image captions include original image IDs.
More than 600 named planetary feature types are discussed in the encyclopedia, covering a wide range of scales–from micrometers to global scale–and also include landform types (structural or topographic features), parts of landforms, terrain types or surface textures, surface patterns, and features identified at wavelengths extending from visible to radio waves (e.g., albedo, thermal infrared, and radar features). The book covers features formed by impact, aeolian, magmatic, volcanic, tectonic, fluvial, lacustrine, marine and coastal, mass movement, sedimentary, desiccation, liquefaction, periglacial, glacial, nival, sublimation, collapse, weathering, and selective erosion or other, including complex processes.

  Planetary Geology Field Symposium, Kitakyushu, Japan, 2011: Planetary Geology and Terrestrial Analogs (PSS Special Issue)
Edited by Goro Komatsu, Kazuhisa Goto and Kenneth L. Tanaka
This special issue is a collection of papers from Asian and non-Asian scientists who participated in the 2011 Planetary Geology Field Symposium in Japan. The topics are wide-ranging, encompassing papers on Mars, asteroids and Mercury, and focussing on methodology, modelling, interpretation of remote-sensing data and terrestrial analogue work. — link to table of contents
Fluvial-like gullies in Gasa Crater, Terra Cimmeria, Mars. Martian Geomorphology (Geological Society of London Special Publication)
Edited by Matt Balme, Alastair Bargery, Colman Gallagher and Sanjeev Gupta
The collection of papers that compose this Special Publication was inspired by contributions to the planetary geomorphology sessions at the European Geophysical Union’s annual General Assembly between 2007 and 2010. The aim of these sessions has been to bring together scientists specializing in remote sensing of planetary surfaces with terrestrial geomorphologists who have in-depth knowledge of specific landforms and processes. The selection of topics covered here, therefore, represents a snapshot of what was most significant at the interface between these two communities at that time. — link to table of contents
A Photographic Atlas of Rock Breakdown Features in Geomorphic Environments
Edited by Mary Bourke and Heather Viles
A comprehensive image collection of breakdown features that are commonly observed on boulders in different geomorphic environments. The atlas is intended as a tool for planetary geoscientists and their students to assist in identifying features found on rocks on planetary surfaces. — Free Download
