This south coast beach just south of Brighton near Dunedin / New Zealand gets golden sand sprinkled in patches, randomly over the mostly white sand. It’s a very pretty effect. When we visited on Christmas morning there was way less gold sand than when we’d visited a few weeks before but I found a nice gold streak at the base of the sand dunes.

Good title, and the golden sand is quite striking. It would be fun to hear a geologist’s ideas on its origin.

Thanks for your mention of the title Gary! I agree it’d be fun to know more, I’ll remain alert to any learning opportunity that may arise 🙂

I did a quick search but couldn’t find an explanation for the golden sands. Does wind expose them? Are they a result of something leaching from the dunes? Something in the ocean water there? In any event, it’s a pleasing effect. It must be lovely as they shift and change.

Hi Linda. I don’t know where it comes from. My guess is that the golden sand comes in from certain currents or during storms and I wouldn’t have a clue where the actual source is. Puzzling!

That makes sense. We have certain seaweeds that wash in on seasonal currents, though they’re not as attractive as your sands.

When I did a little searching yesterday I didn’t find anything, either, but today I came across an article that explains the color of the sand in Golden Bay:

Whether that’s also the explanation for the sand near Brighton, I don’t know.

I really like the look and feel of the dunes in your photos, Liz. My parents retired to a small house in Maine, only a few minutes walk from the ocean and I have fond memories of walking down narrow wooded boardwalks through the dunes to the water.
