If peridotite (mass) remains at the same temperature but begins to melt as it if uplifted closer to Earth's surface....
what would this process be called?
is it decompression melting?
can anyone name/describe a process that could uplift mantle peridotite to start it melting in this way,?
any specific plate tectonic setting where this may be happening now?
Thanks, i appreciate it.

This is indeed decompression melting. This generally occurs in two settings:
1) In 'hot spots' where convection causes the mantle rocks to rise towards the surface.
2) In areas of rifting (including mid ocean ridges) where the overlying crustal rocks are bing streched and thinned.

I'm no genius. I hope this helps you.
thermal ... deformation and crustal uplift.
