This is what I found in a geology text: something to the effect of
several thousand degrees, at least, but almost certainly not as
hot as 10,000 degrees.
Congratulations on asking a question for which we do not yet know
the answer!

My geology text concurs. The temperature is probably
around between 3000 and 5000 degrees Celsius. For comparison,
the temperature at the surface of the Sun is about
5500 degrees Celsius.
