The Lower part mantle
Plates and Crustal plates are not different it can also be called as Crustal rocks

The tectonic plates are floating on top of the molten rock and moving around the planet.
There are actually at least 31 identified lithospheric plates, the plates consisting of crust and uppermost mantle which float on top of the plastic-like asthenosphere of the mantle.
Worldwide, the mountains are the evidence of crustal plates.
The crustal plates (made mostly of low density granitic rock) float on the mantle (made mostly of high density basaltic rock). Convection cells in the mantle move the floating crustal plates around.
