Multispectral data on the composition of rock untis of the surface of Mercury show a widespread role for volcanism and an apparent deficiency in iron in the rocks' minerals.


 

Iron 'Snow' Helps Maintain Mercury's Magnetic Field, Scientists ...

ScienceDaily  Wed, 05/07/2008 - 13:30

New scientific evidence suggests that deep inside the planet Mercury, iron "snow" forms and falls toward the center of the planet, much like snowflakes form in Earth's atmosphere and fall to the ground.

The movement of this iron snow could be responsible for Mercury's mysterious magnetic field.


 

Mercury's shifting, rolling past

Patterns of scalloped-edged cliffs or lobate scarps on Mercury's surface are thrust faults that are consistent with the planet shrinking and cooling with time.

However, compression occurred in the planet's early history and Mariner 10 images revealed decades ago that lobate scarps are among the youngest features on Mercury.

Why don't we find more evidence of older compressive features?
