Open access and geochemistry, what’s the rule?

A long time ago, in a galaxy, far, far away when I was an undergraduate student (I guess it must have been around 2002), I first met the principles of Open Access (OA). A few years later (in 2006 or 2007), I deposited my PhD manuscript in the French repository HAL (a name chosen in memory of Stanley Kubrick’s film “2001: A Space Odyssey”!?) and started to use HAL as my repository for all of my articles: OA the GREEN way! Today, all of my publications are accessible there with OA. Unfortunately, too many colleagues still don’t pay much attention to OA, and a part of their work is not freely accessible, placed behind a paywall.
