Naughty Geology

A few months back, I blogged about the client with a spam filter so tight that it embargoed emails about single young zircon dating. After conferring with said clients, it turns out that they’ve had other issues as well. In its animatronic zeal to rid the internet of pornography, this filter also blocks image files that it suspects are explicit. What sort of images? Well, anything containing a lot of pink, as it turns out. So, rose quartz, rhodocrosite, Mg-rich garnets, and other titillating mineral images have been known to disappear into the computer program’s private locker. Luckily they ship geologic maps as GIS files instead of images, or I’m sure they’d be targeted as well.

This got me thinking. How common are explicit geologic formations? You’d think that will all the zillions of folded, rounded, curved, or protruding structures on this planet, at least a few would be shaped like something that would constrict the coronary arteries of a shrill old censor. So, this is my challenge to the blogosphere: Find juiciest, most risqué geologic image that you feel comfortable posting, and put it out on the internet. Your traffic in tragically maladjusted lapidarians will expand tremendously, I guarantee.

Sadly, all I can offer in this department is this backscattered electron image of a rutile. To most people, it is simple igneous compositional zoning of Nb, Sn and W, which reflect electrons more efficiently than titanium and therefore appear bright. But to the dirty regolithic mind, this only needs legs, arms, and a head to become a swimsuit model. And no, I don’t need to leave the lab more often.
