Summary:Calcite spheres and ellipsoids = or <0.4 mm in diameter occur abundantly in Pliocene sediments in a well drilled in the Beaufort Sea. They consist of fibrous and platy calcite enclosing grains of baryte, quartz, feldspar and clay minerals, the last three being predominantly detrital. The spheres and ellipsoids are interpreted to have formed during early diagnesis as micronodules, probably at or near the sediment-water interface. However, a faecal pelletoidal origin cannot be totally ruled out. [R.A.H.]
