Thanks Carl;
I guess a lot of it depends on how you define "ore deposit".
Presumably, an ore deposit could be huge .. or say one tiny nugget.
I guess ore could form, the external environmental conditions could reverse the process, and then deposition could happen again … the net result might still be said to be an "ore deposit" but microscopically/sub atomically, not exactly identical to the first one.
All sounds like scale/word definition stuff.
I think the scale limits of what one defines the system to be acting over is key, also. (As are the time limit parameters)
Cheers
