EDIT
It is not possible.
We do not accept proposals for identify-this style sites. – animuson♦
Ok, so I went to Area51 and I posted a proposal to open a new site.
If we remember it, we received ~5 questions each day wich is more than Earth Science ratio (2.6 questions/day). This is enought traffic for a new site.
I think we could manage it better on a separate site with the guideliness we posted with effort.
Reasons to open a new site
There are a lot of users on the net searching to identify the minerals or rocks they find. The site would have yes or yes traffic. We received ~5 questions each day.
Reasons not to open a new site
The posters use not to post info and a bad picture. We tried to help them ask better with this post, leaving an example about how to ask.
It is sometimes difficult to identify the pieces and geologists may don't want to participate.
