There's been very few scientific studies published on slickensides. The term was first used used in England in the early 19th century to describe the polished, ribbed and fluted faces found in lead ore-bearing veins along a fault.The common slickenside is no thicker than the width of a hair and seldom exceeds the thickness of a playing card.
The greatest thickness of coating and deformed layering in research documents I can access is less than 5 mm. Here's photos of my find that is 3X thicker! This is indicative of a very high slip-rate and suggests a cataclysmic event happening right here in Colorado. I'd be interested in any information on similar slickensides.

Here's a set of pics of the "best" slickenside I had ever collected...until I found the one at the new crater. It is easy to see that even an intense slickenside is usually very thin. Many times, folks won't even notice a slickenside feature while rockhounding. Since mineral deposits and slickesides are commonly found together, it is always a good idea to keep an eye out for them when prospecting.
