Update of a Venus deposit on Mars

A recent post (July 13th) discussed an interesting ‘deposit’ on Mars’ surface and cited a published paper giving details. A new paper, “The Medusae Fossae Formation as the single largest source of dust on Mars” by Lujendra Ojha et al., (referencing 70 papers) concludes as stated, that this single ‘formation’ is the origin of most of the dust on Mars surface to this day. The analysis is simplified by the enormous extent of the deposit, its obvious erosion by wind (yardangs) and the unique ratio of sulfur to chlorine (S/Cl) in the deposit which is measurably present over the entire surface of the planet. The authors state:
“The size of the deposit, prior to its global distribution, is estimated at 5 × 106 km2. The current mean thickness of the MFF exceeds 600 m. A comparable mean thickness between 100 and 600 m over the eroded areas would imply an eroded volume exceeding 3 × 105–1.8 × 106 km3. If distributed globally, this eroded volume of the MFF would be equivalent to a 2–12 m global layer of dust.”

The low density and transparency to radar have led to the conclusion that it is similar to tephra, usually formed when hot liquid lava shoots from the Earth and comes in contact with water. However, there is no evidence of active volcanism and the wide extent of the MFF is not characteristic of volcanic activity. Analysis of deposits close to large volcanoes do not show the characteristic S/Cl ratio of the MFF and its distribution across the entire surface of Mars.
Cyclic Catastrophism, based on the ancient myths of diverse cultures, particularly the oldest, the RgVeda, explained in my earlier post, proto-Venus gravitationally deflected Mars from its ancient orbit, similar to Venus’ today, to an orbit which intersected that of the Earth. When both were visible as worlds, proto-Venus, which was an incandescent liquid planet at 10,000 K, was drawn into a droplet shape, with the pointed end extending toward Mars. This white-hot sulfurous liquid material struck the living surface of Mars covered with oceanic waters. The sulfur was the liqiud rocky-iron surface of proto-Venus which is outgassing sulfur to this day and the chlorine was from the salty water on the surface of Mars. The explosion was witnessed by every culture on Earth and recorded in their myths.
This same event raised the Tharsis Bulge on Mars as evidenced by their proximity in Figure 2. The Bulge was an important factor in the process of transferring life from Mars to the Earth in the next 3,000-years because it forced the lithosphere of Mars to rotate with Tharsis remaining on its equator and thereby its north pole facing the Earth during each geostationary orbit, called a kalpa in the RgVeda. and the tekhi-Horus periods or inundations in Egypt. These events occurred after 4000 BC, before the Bible was composed.
Since the first close pass of proto-Venus to the Earth, 4000 BC, the cause of the K-T extinction, covered the Earth with a layer of out-gassed iridium, its close pass to Mars around the same date, when it deposited the Medusae Fossae Formation, it in all likely-hood also deposited iridium on Mars. Not sure whether Curiosity can test for iridium, but if it can, NASA should check it out.
