Are there any areas on Earth with purplish-colored soil/sand/rock/land? This sort of comes from my related question, but only sort of. Are there any areas on Earth with purplish-colored soil? The purple tint would come from some mineral, perhaps deposited by rivers or volcanic activity.

I don't know exactly what mineral. The only purple mineral I know for sure is amethyst. It does not hafta be pure purple. A purple-brown mix would be just fine.

The line "purple mountains majesty" comes to mind here, but that appears to be just a reddish/purplish sunset reflecting off of brown mountains. I'm looking for something real in the soil/rock, not an illusion.

Purplish sand and purplish rock are okay too. Really whatever the land is, that's what I'm asking for purple color.

One more semi-reference: Apollo 17 actually discovered orange soil on the Moon.
Soil color is highly dependant on the oxides and other minerals in the composition.  Purplish tones appear to be possible by inclusion of manganese oxide compounds.  There are locations in China that have markedly violet soils. 

If you broaden your search to sands as well as soils, there are plenty of examples of garnet-based sands that can appear markedly purple.  California's Pfeiffer Beach is one such location.
