Dark regions on Mars made of glass

From the article: On Earth, such rinds coat volcanic glass weathered by water. How the glassy grains formed on Mars is unknown, but Horgan says magma from Martian volcanoes interacting with water ice and snow is a possibility. That would make these regions (pictured right) potential hotspots for alien life because they would have held chemical-rich water - a key ingredient for life.\ More disclosure.

Was it volcano's or did they have a nuke war and were turned into glass ?...

Mars was supposedly inhabited in ancient times, and 2/3 of the atmosphere destroyed. Supposedly. I would suspect something nuclear because that's the only temperature sand can turn to glass, other than lightning or meteor, but those two would only create small areas of glass. In Libya there is tens of kilometers of fields of shards and plates of glass. "Some geologists associate the glass not with impact melt ejecta, but with radiative melting from meteoric large aerial bursts." - Wiki. In my opinion there is no way a meteor could be responsible, glass on a massive flat surface, and lightning?... [More]

Im trying to find the article now but I remember reading that there was evidence of a natural nuclear explosion millions of years ago.

Heres the article: Natural nuclear explosion on mars And a UM thread on it: Thread

Send a manned mission to Mars and a lot of mysteries will be cleared up.

It is just the glass formed due to volcanoes or it is volcanic glass.There can't be any other source.

Send a manned mission to Mars and a lot of mysteries will be cleared up. Probably to everyone except the tax payers who paid for the mission.
