Thin section of yellow-weathering limestone, Worland Limestone
Thin section of yellow-weathering limestone in the Worland.
This rock
contains much more micrite matrix than the underlying hard gray
limestone, suggesting weaker currents that let more of the fine material
settle to the sea floor. Fusulinid forams dominate this view; the majority
are cut in transverse section. Most of the other skeletal material is finely
fragmented crinoid debris and algal plates. An unidentified non-fusulinid
foram is indicated by the arrow. The scan is in black and white for
maximum resolution.
