It most generally forms small euhedral rhombs, but also some knotlike pellets and
a few well-rounded radially fibrous grains similar to grains of sphaerosiderite. A
few boulder-like masses several inches in diameter are composed almost ...
Sergeant Bluff cores show that sphaerosiderite nodules are arrayed along dark
clay-filled horizontal root traces. Dakota sphaerosiderites are largely free of
detrital inclusions, and comparison with their modern analogues (Stoops, 1983) ...
