Sand & geology
Maspalomas Dunes
lithic-rich (volcanic/collisional terrane)
They were formed by sand from the now subdued marine shelf, when it was laid dry during the last ice age and the wind blew the sand towards the coast of the island.

Predicted regional composition
Q-F-L (quartz, feldspar, lithic) fractions sampled from the GloPrSM global sand model at this beach's location.
F 24%
L 68%
GloPrSM v1.0.0 (IJ_QFL). GloPrSM is calibrated on modern river sand; beach sand in the same watershed is a reasonable proxy but not identical.
Got a close-up photo of the sand here?
Take a picture with a coin for scale and send it over. We're building a global grain-photo library and this beach isn't in it yet.
