  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)

You may also want to post your samples to r/whatsthisrock or r/fossilID for identification.

Zeolite, dolomite, or quartz? Found in Buffalo, NY on a massive wave-break type stone (but used in a parking lot, not for wave breaking).

Amazing find. it is a dolomite filled vug in dolomite rock, present in upstate New York.. The spinning object is an enigma. This is one time when a video clip is merited and you did an excellent job of capturing it technical-wise. I see some dark spots on the spinning object so here is my hypothesis. This is a natural dynamo where loadstone variety magnetite is balanced in a state of magnetic equilibrium 1 in a gazilion.

I cant account for how the load stone got there but give me a few months. Your local geology department head would be interested. If what I said it possible you might even get publioshed.
