RE: Nature Identification Thread #11- Now Paying out Steem Basic Income Memberships to Participants!
Hey @mountainwashere and followers. I hope all is well? Ok let's take a look at this one.
This is an in-situ photo of a rock cropping out near sea level, on a wave cut platform. This is from sea level next to the Indian Ocean. Looks a bit like coral. But not sure...
Boot and camera case for scale. But what do you and your and followers think?
Thanks!
ps. there is of course sand and shells covering the rock in places as well from the nearby beach...
Oooh, tough one! It could be coral, or coral based limestone, certainly. If there's one thing that these threads (and your submissions) are showing me, it's how reliant on non-optical diagnostic criteria I am for rock identification.
Agreed that looks like coral! But not sure. Your observations are sound however.
Full agreement as well that a picture tells a thousand words but as you mention, non-visual observations are also essential with rocks (e.g. reaction with HCl, etc). Great feedback and insight - thanks!
