At this stage the entry point and its antipode virtually converge This convergence results in an almost entirely parallel and horizontal crustal magnetic field.

I believe that there is a relationship between this crustal magnetic pattern and the cloud pattern that is common to all the outer gas giants. If a hypothetical gas shroud were placed over Mars It appears that the storm clouds of the red spot of Jupiter would hang over the point where the entry point and its antipode meet. It is perhaps a shadow of the original impact, influenced in some way by the remnant surface magnetic field. I believe there is a direct relation between Mars as the last stages of a rocky, inner planet, and the outer gas planets.

The process that begins the transformation from rock planet to gas giant and starts to develop the gas clouds around these planets, which serve as rock cores, contributing to the 300 fold increase in mass and the unearthly chemical make-up found in the Gas Giants, I believe is related to their passage through the asteroid belt.
