The text mainly focuses on the Noachian, Hesperian, and Amazonian periods in the geological formation of Mars, providing more information on the more recent eras. While the geological record can offer more data on the recent periods, this information is also limited due to the fact that Mars's geological activity has been slowed down with time, to the point where the planet displays little surface action.
Most of the latest geological activity on Mars can apparently be found in the Tharsis and Elysium sectors of the planet. This factor is detrimental for the overall article, as even though it can provide significant information regarding the recent years in the geological evolution of Mars, the fact that the planet's surface did not experience notable changes lately prevents the authors from providing considerable demonstrable information.
Large floods were initially responsible for giving shape to surface of Mars and volcanism continued the process in the years subsequent to the floods. However, the presence of both of these processes is no longer felt on Mars, as it is no longer influenced...
Ice is dominant in the era lasting from the end of the Hesperian and to the present day, and researchers are currently engaged in finding as much as they can, relating to the planet with the help of the ice formations.
Carr and Head III are extremely satisfied with the progress made by the international Mars exploration program and this is clear throughout the paper, as a lot of information they use comes from this source. Nonetheless, they agree that the program has brought much more puzzles than it has solved, as the discoveries it made do not compensate for the mysteries that it brought into public attention.
"Geologic history of Mars" is merely a document intended to raise public attention, informing them with regard to the geological evolution experienced by the planet Mars. Despite the fact that the article cannot be compared to books written on the topic, it still manages to provide notable and ground-breaking data.
