We wish to extract the topology from scanned maps. In previous work [ 151 this was done by extracting a skeleton from the Voronoi diagram, but this required vertex labelling and was only useable for polygon maps. We wished to take the crust algorithm of Amenta, Bern and Eppstein [3] and modify it to extract the skeleton from unlabelled vertices. We find that by reducing the algorithm to a local test on the simple Voronoi diagram of point sites we may extract both the crust and the skeleton simultaneously. We show that this produces the same results as the original algorithm, and illustrate its utility with various cartographic applications.

Except for radiogenic components, the amount of noble gases in the solid crust is safely assumed to be insignificant in terrestrial noble gas inventory. In general, except for in situ derived radiogenic and nucleogenic noble gases, trapped noble gases in crustal rocks are of an atmospheric origin. Because of the higher concentration of U, Th in the crust than in the mantle, however, nucleogenic Ne isotopes are often discernible in crustal materials. Near the Earth's surface, down to a few meters in depth, cosmic ray-induced cosmogenic Ne and He isotopes can also be observed. In deepocean bottom where sedimentation rate is extremely slow, extraterrestrial noble gases carried by cosmic dusts become conspicuous. In this chapter, we will discuss these unique features of noble gases in the crust.

On my paranormal-themed sub-podcast Crust to Crust AM, I investigate the connection between McDonald's experimental new beverage restaurant CosMc's and extraterrestrials from outer space.

In the mirror I'm giving a lecture on geology, but when I touch my mouth, there's just some clay beads standing in for teeth.I think, Yeah, I ate the stamp with the wildflowers, but this is a whole passageway I was hoping to ditch.Dan and Julie are in the next room making out, so I splash some root beer on my face and continue preaching science.This time I'm on in Spanish, and I'm laughing a little, 'cause it's not the talking I took in school.I'm pretty good, I think, and I'm wondering if somehow there's a videotape of all this I might watch later.There's always that rocky part in the afternoons that gets me real lonely, and this is just the thing to shepherd me back up top.Another minute goes by, or an hour or four, and I'm making lists of the ways wincing is spelled.I can think of seven when the door opens, and it's Julie, who's ready to go, and she's hugging the doorframe loose, with no connection, but I'm so close to the tiles that I have trouble not kissing each one goodbye.
