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.

That's a fantastic find Johnny!!
 Why does the cut look so rough though? What kind of blade are you using to slab them on the diamond saw if you don't mind me asking.

What kind of blade are you using to slab them on the diamond saw if you don't mind me asking.Good Morning Mrs. CP, True story...I swear! Years ago my wife agreed to spend $75 our of our company budget to purchase a used diamond saw that was being advertised in the local paper. The nice lady that owned the saw had used it to "rough" material for many years before we took it over. Our vintage Star Diamond Industries Model 10c is still running on all original factory equipment including blade and belt! It has cut A LOT of meteor wrongs along with a good share of hard space rock. Man can you hear the difference in the blade singing when it gets hold of a real meteorite. Our old saw wobbles a bit when it eats through the chondrites but still gets the job done, eventually. A few hours of hand polishing selected specimens with wet/dry sandpaper and the rough saw marks disappear. I know there is a great need for me to upgrade my equipment but most of the company resources go to prospecting...travel, gas, food, claim maintenance fees, etc. Now that I've retired from my scientist/researcher position with the Colorado Department of Natural Resources, I have more time to follow-up on my projects but less disposable income to invest in other things like work saving devices. Have a great day. We've got snow over here.  Good time to break out the sandpaper  -------------------- Annual Dues Paying Member Since 2008
