Blast from the Past: It’s all about scales

It has often been said that geology is the study of scales. Time scales, large scales, small scales and many others. Indeed, one of the most crucial parts of any photo or map is the scale.... [[ This is a content summary only. Visit my website for full links, other content, and more! ]]

Imaggeo on Mondays: A fold belt within a grain

 CH,
Tiny crinkly folds form the main basis of today’s Imaggeo on Mondays. Folding can occur on a number of scales; studying folds at all scales can reveal critical information about how rocks behave when they are squeeze and pinched, as described by Sina Martin, from the University of Basel. Although many geoscientists have seen such fold structures many times before, if you noticed the scale bar in the lower left of the image, you might be surprised of the small scale of these folds! The [...]

fun stuff to drill through (3)

This is another entry in the intermittent series I started in October (previous installments are here and here) regarding material that is a giant pain to drill through. Another material that causes headaches is bedrock which changes drastically and unpredictably over small scales. Examples include small-scale fault zones, which may include significant fractures and breccia zones above or

It has often been said that geology is the study of scales. Time scales, large scales, small scales and many others. Indeed, one of the most crucial parts of any photo or map is the scale. Furthermore, geologic concepts can be applied from the planet scale to the atomic scale and every size in between.

Diamond as an Ultradurable Component in Micromachines

“Diamond may be the ideal substance for MEMS devices,” says NIST’s Craig McGray. “It can withstand extreme conditions, plus it’s able to vibrate at the very high frequencies that new consumer electronics demand. But it’s very hard, of course, and there hasn’t been a way to engineer it very precisely at small scales. We think

A River Runs Through It - Sometimes At Flood Stage 

En Tequila Es Verdad [2011-09-15 09:25:25]  recommend  recommend this post  (167 visits) info
Before Anne Jefferson, floods bored me. I didn't used to put a lot of thought into how rivers overran. I knew the basics: too much water = overflowing banks. Simple equation, one even an Arizonan can solve. We watched it happen. Rain had a difficult time soaking into hard desert earth. So, every rainstorm, there would be flash floods, and every monsoon season, at least a few people who didn't quite grasp the fact that those floods were, in fact, flash, and furious: they'd get caught by [...]

Eater of Ammonites

Durophagy is technically the adaptations involving consuming foods that require crushing. At small scales, this can include insects, while at larger scales (where insects wouldn’t be consumed) this typically involves: cracking nuts, eating eggs, cracking crustacean or mollusk shells, etc. One of the most interesting durophages out there are the placodonts, but in the absence
