Found around some plants in my yard.  Very bright color,  a few different shapes.  Would appeciate any help in ID.  and age would be great.

It would really help if you would include the location in your post. The more information you can give for ID the better.

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.

I agree that this looks like a sedimentary structure. 

Geological in origin, rather than biological.

Thank you.  I’m very new to this.  Auke Bay Alaska.  Glacial silt.  This is the other side. AF89F8AA-31E9-43EF-9FCD-806A5CE512B6.thumb.jpeg.e45b45e35532d72dd904b65345285a2f.jpeg

Is this material blueish when it's first exposed ?

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.

So, it might be considered claystone?

Glauconite is mentioned in the makeup of a similar formation here in Maine. Such clays make good impermeable layers.

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?
