New Questions Raised in Mars' Geomorphology

A study done by the Universitat Autònoma Barcelona (UAB) on subterranean springs in the central pre-Pyrenees of Catalonia has revealed new findings into the formation of the Martian terrain. Several previous studies had been conducted, comparing various features of Earth to several of Mars' geological formations. However, this new research focuses on the study of geological records originated by ancient karstic springs. It specifically studies forms dating back over 250,000 years -- tufa mounds -- which are practically unknown in Europe, having been until now only described in Australia.

It is always interesting to apply knowledge of our own planet to help explain certain features of other planets. This is an especially neat finding because it suggests that these giant formations on Mars greatly resemble the subterranean springs on Earth. As the subterranean springs in Spain were formed by underwater cold springs, this makes it possible that the mounds on Mars may have required water as well. This just proves that in order to learn about other planets and study them in depth, we must understand our own planet first.

That in an interesting connection between the subterranean springs in Spain and these mounds on Mars; this could be a newfound discovery that might further support water on Mars at one point. Given all the evidence for water on Mars, I believe water must have been present for a substantial amount of time on Mars. My theory about Mars, although there has been no discovery of fossils or anything of that kind, is that Mars was once very similar to Earth, with living organisms etc. until the planet became geologically inactive and everything living and existing (including water) was eventually wiped out, leaving Mars as the dead planet we know it to be today.
