Hey Everyone,
Just got this stone in and wondered what it was?
Hope it's clear enough...

Thanks,

Looks like some slabs that i have, but not sure that i ever really got a name with it.  Really nice little globules that look like chalcedony to me.  If i ever can figure where i got it, i will see if there was a name with it.  I actually think, that someone here sold it to me 4 or 5 years back.

Can you give us more hints?  What is the matrix like, is the cut surface as smooth as it looks or is that from being wet, etc. It looks really neat whatever it is.

The top one is a picture of the matrix...  The last one shows the meat of the rock...
the main part of the rock is very smooth...

Thanks for any help you can give....  :)

  I will venture a guess  =  dunno28  = a chunk of silicified
 mudflow with brecciated rock throughout.

Saw this in Patti Polk's agate/Jasper book. Looks similar?

Yukon's jades theory sounds plausible but I think it may be a type of limestone initially . Many limestones actually have large amounts of silica and can be very hard. At times this silica is part of the initial deposition and at times it is because of the intrusion of silica by hydrothermal injection. The differential weathering of the surface shows that the inclusions are a bit harder than the matrix. This is often true of pebble conglomerates because the pebbles tend to be very hard chert. Flat pebble conglomerates also have differential weathering like this despite the fact that the pebbles and the surrounding matrix are limestone. I think it may be a disturbed , brecciated flat pebble conglomerate.You can find google images of  flat pebble conglomerates and I have bought slabs of them at rock shows so they are being collected by someone other than me..
