- •
Two mafic–ultramafic intrusions yield consistent magma emplacement ages of 129 to 126 Ma.
- •
Partial melting of the relatively juvenile SCLM in response to the peak of extension.
- •
Fault reactivation and structural constraints played an important role.
- •
The composition of mafic–ultramafic intrusions provides a snapshot of SCLM in a reactive tectonic belt.
