edd Posted December 6, 2015 Share Posted December 6, 2015 Found it walking the shores of a lake in Romania, I'm thinking concretion but I like to be wrong. " We're all puppets, I'm just a puppet who can see the strings. " Link to comment Share on other sites More sharing options...

Auspex Posted December 6, 2015 Share Posted December 6, 2015 Looks like pyrite and limonite. Can't completely rule out some kind of organic origin.

abyssunder Posted December 6, 2015 Share Posted December 6, 2015 ...or maybe Siderite?

Auspex Posted December 6, 2015 Share Posted December 6, 2015 ...or maybe Siderite? Also possible; I thought pyrite because they seem to be cubic.

howard_l Posted December 6, 2015 Share Posted December 6, 2015 Could be pyrite altering to Goethite Howard_L http://triloman.wix.com/kentucky-fossils Link to comment Share on other sites More sharing options...
abyssunder Posted December 6, 2015 Share Posted December 6, 2015 For me the crystals on the surface looks like those of this specimen. I'm in the idea of the replacement of Calcite and Dolomite by Siderite. I think, the Siderite crystallites should be oxidized to form a secondary fase of brown ferric oxide, to be Goethite.

Auspex Posted December 6, 2015 Share Posted December 6, 2015 It could also be hematite after cubic pyrite, by oxidation.

abyssunder Posted December 6, 2015 Share Posted December 6, 2015 I agree!The concretion is reddish,could be from the presence of Hematite.Is that possible, in a third phase, Goethite passing through Hematite in diagenetic crystallization and oxidation process?

Auspex Posted December 6, 2015 Share Posted December 6, 2015 No matter the diagenetic process, it is possible that this could have started out as a coprolite. I wish I knew the geology of the area!

edd Posted December 6, 2015 Author Share Posted December 6, 2015 (edited) That's what I was thinking, coprolite... but I'm not familiar with the geology here either, I'm sure abyssunder knows it better then I. It was found in Tulcea region. I'm going to keep this "peanut" and take it back with me Jut noticed it has a little more on its side.

Auspex Posted December 6, 2015 Share Posted December 6, 2015 ...Jut noticed it has a little more on its side. If that is a continuation, and not a separate specimen, it could be a fecal pellet-filled burrow.

abyssunder Posted December 6, 2015 Share Posted December 6, 2015 Yep!I knew, when edd comes back to the original "state" something is wrong...The Tulcea region from the far east of Romania is situated in the Danube Delta( a labyrinth for those who don't know the channels), part of the Dobrogean plateau whit it's eroded mountains of max 467m peak (Devonian - Permian at north, Cambrian - Silurian in central zone), the whole ensemble is arid all of the year looking like in desert.As I know, the sediments of Tulcea are Werferian (Lower triassic) conglomerate, limestone and dolomite.Maybe, is coprolite...

edd Posted December 7, 2015 Author Share Posted December 7, 2015 Hahaha, don't worry, I'll leave some stuff behind for you. Soon I'll post some things I found from a 6000 year old settlement... including a human tooth. " We're all puppets, I'm just a puppet who can see the strings.
