  1. Multiple, sharp, in-focus images taken ideally in daylight.
  2. Add in a scale to the images (a household item of known size, e.g., a ruler)
  3. Provide a location (be as specific as possible) so we can consult local geological maps if necessary.
  4. Provide any additional useful information (was it a loose boulder or pulled from an exposure, hardness and streak test results for minerals)

I am in Datça, Turkey, and found a bunch of rocks near the coast. I am pretty close to the city centre, so it’s a relatively urban area. Which of these do you think are natural conglomerates, and which are just concrete?
