Heavy Minerals Of The Cretaceous Hell Creek And Paleocene Ludlow Formations Of Slope And Bowman Counties, North Dakota, Robert A. Farris
Theses and Dissertations
The Cretaceous Hell Creek and Paleocene Ludlow Formations of southwestern North Dakota are nonmarine sediments of alluvial origin. The heavy minerals of these formations were specifically studied to determine the source rock types and their provenance, and generally assess the diagenetic processes which affected the heavy minerals.
The heavy minerals include zircon, rutile, tourmaline, garnet, ilmenite, spinel, apatite, epidote, sphene, pyroxene, dolomite, biotite, andalusite, pyrite, monazite, and barite. Most of the heavy minerals have angular shapes, indicating one cycle of erosion and deposition.
The heavy mineral percentages of the concretions and surrounding sediments were compared within and between the Hell …
