That's a good question...but I don't think sedimentary rock such as limestone, etc., can be molten and then, when cooled, return to a
'sedimentary' state...the heating and cooling process would cause molecular changes so that the stone would be igneous, rather than sedimentary,
after it cooled.
Also, very few human artifacts would survive immersion in magma, as the temperatures at which stone becomes a liquid
(700 °C to 1300 °C
) is high enough to either completely melt or completely incinerate most materials
we commonly use except for some metals, and gemstones. The iron head of the Texas Hammer would probably have survived immersion relatively intact,
though it would have been brought very near to it's melting point and would have undoubtedly suffered some visible effects of that, perhaps some
slumping or other distortion of its shape...you do not have to liquefy iron in order to make it soft and malleable, as any blacksmith would tell
The wooden handle would most certainly not have survived immersion in magma, however. So for this artifact, and probably any artifact caught in
sedimentary rock, it seems to me that we can rule out magma intrusion as an explanation.
I could be wrong though.
