Bill Friday from the Senior Center gave this to me the other day. Said it was pudding stone and came from a 5'x5' chunk they found on a field trip to Hackleburg.  |

I don't think that is pudding stone... Looks like it was found on a beach.... Based on the way it looks and from my previous experience i an guessing that there is a man made metal object in the center and the rust cemented everything... Try taking a strong magnet to it (rare earth magnet)

well the cementing agent is iron that is for sure... possible it could have been next to something iron

natural iron rich soil. guess ancient river botton rock, maybe of the conglomerate line, but not pudding stone.

Mr broseph82, back in the early 1960's, I went with my uncle to a gravel pit near Haleyville Alabama and the gravel was natural rounded stone. There were agates and petrified wood and quartz gravel stones already tumbled. In sections of the pit were pieces of conglomerate like you posted. The iron maybe a form of bog iron.

it's definitely a conglomerate. hopefully the cementing matrix will be solid enough to allow you to slab it. I would speculate that the slabs will look pretty cool.

As I understand it, there is a type of bacteria that uses iron (in water) as it's energy source. They "deposit" the depleted iron onto the rocks/soil they live on. Some of these iron deposits can weight many pounds and are sometimes mined. I have a piece about 3 lbs that is almost solid iron, but have heard of them in New England that are up to 100 lbs.
I am guessing this is what this is.

love conglomerates. Pudding stone is a sort of generic term used regionally to denote various or general types of conglomerates, and in some cases (like here in Michigan) to denote specific conglomerate types. Here it is usually not considered pudding stone unless the conglomerate contains red and black jasper. I have heard people here use the term to denote any sort of conglomerate as well. Nomenclature is sometimes a real pain especially when we have folks on the forum from so many regions! Good find, show us what it is like if you cut it! |

Lab guy told me it is prohibited to slab or cab this stuff. Said it will eat the the blades and sanding belts. I told him I was going to soak it in iron out and he said "no, no, no, don't do anything to it." Ha ha ha |
