Earth-like Habitats in Planetary Systems

, 2014
Understanding the concept of habitability is related to an evolutionary knowledge of the particular planet-in-question. Additional indications so-called "systemic aspects" of the planetary system as a whole governs a particular planet's claim on ...

Absolute ages from crater statistics: Using radiometric ages of Martian samples for determining the Martian cratering chronology [PDF]

In the absence of dates derived from rock samples, impact crater frequencies are commonly used to date Martian surface units. All models for absolute dating rely on the lunar cratering chronology and on the validity of its extrapolation to Martian ...

The Cratering History of Asteroid (2867) Steins

, 2010
The cratering history of main belt asteroid (2867) Steins has been investigated using OSIRIS imagery acquired during the Rosetta flyby that took place on the 5th of September 2008.

The KREEP-rich circum-Lalande region: A candidate landing area for future lunar crewed missions

Earth and Planetary Physics
The lunar magma ocean hypothesis suggests that the primordial KREEP (an acronym of potassium (K), rare earth element (REE), and phosphorus (P)) was the final product of fractional crystallization. However, the primordial KREEP (a.k.a.

Revision of the Martian relative age chronology [PDF]

This study has provided a more detailed chronology than currently exists in the literature and has created some changes to the currently accepted geological evolutionary sequence of Mars.

Glacial and marine chronology of Mars [PDF]

A hydrological model involving episodic oceans and ice sheets on Mars has been presented by Baker, et al. One of the main uncertainties concerning this model is the age and correlation of these events. Even more uncertain are their absolute ages. However,

Identification of tephra horizons in a glacier on the Ushkovsky volcano (Kamchatka)

Лëд и снег
Identification of tephra and its allocation (association) with known eruptive events allows obtainng chronostratigraphic markers, on the basis of which an age scale for dating glacial strata can be developed.

Lakes [PDF]

, 1992
Lakes have always held an aesthetic fascination for people; they figure prominently in both art and literature and have even been endowed with spiritual qualities. For example, the nineteenth century American writer Henry D.

Terrestrial Impack Cratering Chronology : A Preliminary Analysis

Journal of Astronomy and Space Sciences, 2001
We have recently compiled a database of the properties of 192 impact craters, which supercedes previous compilations. Using our database, the impact structures found in North America, Europe and Australia have been examined; these cratonic areas have been relatively stable for considerably long geological periods, and thus have been best preserved.
