caldigger Posted December 23, 2018 Share Posted December 23, 2018 It would really help if you would include the location in your post. The more information you can give for ID the better. Link to comment Share on other sites More sharing options...
Rockwood Posted December 23, 2018 Share Posted December 23, 2018 It's quite likely that this is a dewatering feature. They form as fluids are being pressed out of pore spaces when sediments are accumulating. Often relatively impermeable layers being breached are the cause. 3 Link to comment Share on other sites More sharing options...
Fossildude19 Posted December 23, 2018 Share Posted December 23, 2018 I agree that this looks like a sedimentary structure. Geological in origin, rather than biological. 2 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Bryon K Young Posted December 23, 2018 Author Share Posted December 23, 2018 Auke Bay is in the Mendenhall Glacier area. When digging we often run into what we call blue clay. It has been explained as glacial silt from retreating Mendenhall. Link to comment Share on other sites More sharing options...
abyssunder Posted December 23, 2018 Share Posted December 23, 2018 So, it might be considered claystone?

Rockwood Posted December 24, 2018 Share Posted December 24, 2018 Glauconite is mentioned in the makeup of a similar formation here in Maine. Such clays make good impermeable layers. Link to comment Share on other sites More sharing options...
KimTexan Posted December 24, 2018 Share Posted December 24, 2018 Could you please post a couple more pics of the top side from different angles? Is that top layer kind of mother of pearl iridescent or more like oil slick rainbow colors type thing? Link to comment Share on other sites More sharing options...
