Fault in the Boulder Batholith
Posted by Callan Bentley
Last week, we took a closer look at the xenoliths (MME’s?) in the Boulder Batholith. Here is a look at a fracture, perhaps a small fault, in that same outcrop.
There are no marker units by which we could detect offset here, so we can’t say for sure it’s a fault. But definitely weathering has been strongly enchanced along the trace of this planar feature.
I have found that some of the faults on earth may have been caused by some type of wave from a supernova that hit earth sometime around 250 million years ago. What would you say is the age of this structure?
Hi James,
The Boulder Batholith is Cretaceous in age, like all the major western North American batholiths. So this fracture / putative fault must be younger than that.
When you say “I have found that,” do you mean “I have heard that,” or “I have concluded that”? I’m a little confused – since I can’t for the life of me figure out how a supernova triggers faulting in rocks in another solar system (or perhaps another galaxy). Maybe you could explain your logic (or the logic of whoever told you this idea) about supernovae being capable of making faults.

I have to laugh at how long I wrote this! But, I do my own research and what I say is all true. Based on my findings and comparing photos from space to rocks on earth.
