The following report presents a regional study of the extent, thickness, lithology, stratigraphic relations, age, depositional environment, and tectonic history of thick sulfate deposits and associated salts of sodium and potassium.

The following document is a third-year progress report for the period June 1, 1978 to May 31, 1979. The overall objective of the project is to study the effects of seeding techniques, species mixtures, fertilizer, ecotypes, improved plant materials, mycorrhizal fungi, and soil microorganisms on the initial and final stages of reclamation obtained through seeding and subsequent succession on disturbed oil shale lands. Plant growth medias that are being used in field-established test plots include retorted shale, soil over retorted shale, subsoil materials, and surface disturbed topsoils. Because of the long-term nature of successional and ecologically oriented studies the project is just beginning to generate significant publications. Several of the studies associated with the project have some phases being conducted principally in the laboratories and greenhouses at Colorado State Univerisity. The majority of the research, however, is being conducted on a 20 hectare Intensive Study Site located near the focal points of oil shale activity in the Piceance Basin. The site is at an elevation of 2,042 m, receives approximately 30 to 55 cm of precipitation annually, and encompasses the plant communities most typical of the Piceance Basin. Most of the information contained in this report originated from the monitoring …

"This report summarizes published geotechnical properties of raw and retorted oil shales from the Green River Formation. Basic physical properties including gradation, specific gravity and Atterberg limits and engineering properties including compaction, permeability, settlement, soundness, and strength are summarized and discussed. Where appropriate, conclusions are drawn about the suitability of retorted oil shales as a geotechnical construction material. Appendix A discusses three retorting processes used to extract oil from oil shale" (abstract, para. 2-3).

"CER Geonuclear has developed, in cooperation with the Atomic Energy Commission, a set of detailed plans utilizing nuclear explosives for an underground engineering experiment called project Rio Blanco. The overall objective is to prove the commercial feasibility of using nuclear explosives to recover commercial quantities of tightly held natural gas in the Piceance Basin."
