Polished stone axes, and similar axes made of copper and bronze, are sometimes thought to represent lightning stones – which suggests a connection with lightning or meteorites. However, Gene Gangle of Oregon says that polished or flat surfaces of quartz, when rubbed together, create electrical discharges that can, theoretically, ionise the air and create ozone.
Whilst some people have claimed the solar wind affects ozone levels in the atmosphere, pushing it away from the poles and creating the illusion of an ozone hole, we may wonder what else the solar wind is capable of doing as far as ozone is concerned. After all, a large part of the atmosphere is ionised.
