I was searching for the meaning of the, " seek past life" as on the logo 2020 .
I was concerned about the way that opposites are related to ,"action and reaction" of the sides to certain events. So I looked up where the exact opposite to my place of birth was located on the Earth map. So i found the area as the one directly opposite. It's name is ,"southern Australia" and it's probably one of the nest places to train for walking and living on Mars. I have included some images from google Earth and some nasa images of regions that look similar. In this way i could search for the place and the types of hard rock samples to be found there and why they are there. It seems that much of the details around the ,"blue dunes" may be answered by looking into the article : /www.energymining.sa.gov.au/minerals/geoscience/geology/regolith_of_south_australia Some interesting quotes about the cementing of rock matter just as the blue dunes on mars must be cemented. Also some crucial information about geological features that have remained as they were long long ago. This geological age where the Earth remains as it was, could be the way that Mars also appears to be. |
Here are some facts concerning the images from the south Australian region:
I found them interesting because they describe the possible types of geological
details that are observable on Mars.

Preservation potential of regolith, already poor due to its formation close to the earth’s surface, decreases generally with time, thus only fortuitous and major culminations of regolith development will be retained in the older rock record.
The formation of regolith is closely related to weathering driven dominantly by changes in climate.
Increased aridity and persistent strong winds during the Pleistocene caused the development of extensive dunefields like the Simpson and Great Victoria deserts.
Regolith is an integrated expression of geology, climate, groundwater, topography, geomorphic processes and landscape evolution and has a very close empirical relationship with landforms, both present-day and past. Landforms are themselves a reflection of climate, geology and predominantly near-surface geomorphic processes (Craig 2005).
insight
why this are is good for astronaut training for mars.
the article continues:
In situ regolith refers to weathered rock that has undergone either no or minimal physical transport (Eggleton 2001) and accounts for 25% of South Australia’s regolith by area.
insight
why there are blue areas on mars.
Induration is defined as ‘the hardening of a rock, rock material or regolith by the action of heat, pressure, or the introduction of some cementing material not commonly contained in the original mass:
