Paleomagnetic dating of dedolomitization in Cambrian-Ordovician Arbuckle group limestones and Pennsylvanian Collings Ranch conglomerate, southern Oklahoma

OSTI ID:5797882

Paleomagnetic and petrographic techniques have been used to date dedolomitization in stratigraphic and tectonic dolomites exposed in the Arbuckle Mountains, southern Oklahoma. The authors examined red dedolomites and their dolomite precursors from the Cambrian-Ordovician Arbuckle Group and dolomite clasts in the Pennsylvanian Collings Ranch Conglomerate. Authigenic hematite is associated with the dedolomite and precipitated as a result of the dedolomitization process. Dedolomite is associated with paleokarst and fractures, burrows, Liesegang bands, and red rims on conglomerate clasts.
