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. Thanks.
