Scientists have discovered a new type of “rock” that will
stay in the Earth’s strata forever.
The rock is made out of plastic rubbish and other detritus, and
has been dubbed Plastiglomerate.
Basically, it’s what happens when plastic melts on the beach
and gets a bunch of stuff stuck to it- Shells, more sand, bits of coral,twigs
and bird poop, whatever.
You could call it Metamorphic Garbage, if you were so
There are two types of Plastiglomerates, as discovered by
research done on Kamilo Beach in Hawaii.
In Situ plastiglomerate is the rarer type, which occurs when
plastic melts onto existing rocky outcrops.
Clastic plastiglomerates form as loose structures, and are much more common.
Plastiglomerate was first discovered
by the oceanographer Captain Charles Moore, who thought that molten lava had
melted the plastic to create the new “rock”.
certainly be around long after the human species has died out or evolved into
something else, and will provide a hardy, datable, anthropological record of our
Note: It doesn’t seem that anyone has found a use for it yet, although here
at Australian Mining the idea has
floated that if ever the technology of plastic manufacture is lost, we may well
end up mining Plastiglomerates and trading them as a valuable commodity.
