Tree mold

[Marsrocks]

A "tree mold" is created when a lava flow hits a tree. The lava begins to wrap around the tree, and then solidifies in place as rock. Later, the tree burns, dies, deteriorates, and nothing is left of it. The only thing left is the rock that was wrapped around it. Now, a round shape might also be created if lava flow hits a softer rock column (that later deteriorates), or a boulder that later deteriorates and disappears. Nevertheless, this is something we should be on the lookout for.


This is a possible tree mold from the Curiosity rocknest pan.  I have not located the raw image.

There are two more tire-shapes like tree molds in this image from curiosity sol 1049:

Shallow depth points to remnant of volcanic mud pool. There are many other examples highlighted by Curiosity.
