Fault in the Boulder Batholith

Posted by Callan

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.
