Predicted regional composition
Q-F-L (quartz, feldspar, lithic) fractions sampled from the GloPrSM global sand model at this beach's location.
Q 13%
L 86%
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.

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.
