    A HISTORY OF THE GILSONITE INDUSTRY by NEWELL C. REMINGTON m A HISTORY OF THE GILSONITE INDUSTRY by Newell C. Remington This paper was submitted by the author in unpublished form in April, 1959, to the Department of History, University of Utah, in partial fulfillment of the re­ quirements for a Master of Science Degree. Typed by Pauline Love and Lithographed by Robert L. Jensen Salt Lake City, Utah Digital Im age©2006, Newell C. Remington. All rights reserved. Copyright Newell C. Remington 1959 Manufactured in the United States of America Digital Im age©2006, Newell C. Remington. All rights reserved. DEDICATION --To the Indomitable miners who, with crude imple­ ments and disregard for hazards and physical discomfort, helped to develop a prosperous, modern gilsonite industry. Digital Im age©2006, Newell C. Remington. All rights reserved. PREFACE In 1957 the American Gilsonite Company opened a revolu­ tionary refinery near Grand Junction, Colorado, which had cost them $16,000,000 to build, and began reducing the gilsonite--a solid hydrocarbon--to high-grade gasoline and pure carbon-coke at the rate of about 700 tons per day. Just as incredible is the fact that gilsonite was and is conveyed from Bonanza, Utah, across the precipitous Book Cliffs to the refinery through a pipeline. The opening of this magnificent plant was eighty-eight years removed from the year 1869 when the blacksmith of the Whiterocks Indian Agency attempted to b u m gilsonite as coal in his forge with rather dreadful results. During the interval so many human events occurred in relation to gilsonite--a rare bitumen closely related to grahamite and glance pitch--that it was felt to be an adequate and deserving topic for thorough historical treatment.

  • UINTA-PICEANCE BASIN PROVINCE (020) by Charles W
    UINTA-PICEANCE BASIN PROVINCE (020) By Charles W. Spencer INTRODUCTION This province trends west-east, extending from the thrust belt in north-central Utah, on the west, to the southern Park Range and Sawatch Uplift in northwestern Colorado on the east. The northern boundary is defined roughly by the Uinta Mountain Uplift, and the southern boundary is located along a line north of the axis of the Uncompahgre Uplift. The province covers an area of about 40,000 sq mi and encompasses the Uinta, Piceance, and Eagle Basins. Sedimentary rocks in the basin range in age from Cambrian to Tertiary. Spencer and Wilson (1988) provided a summary of the stratigraphy and petroleum geology of the province. The Uinta and Piceance Basins were formed mainly in Tertiary time. The Eagle Basin is a structural feature east of the Piceance Basin and coincides in part with the Pennsylvanian-age Eagle Evaporite Basin, although the present-day Eagle Basin is much smaller than the paleodepositional basin. Numerous oil and gas fields have been discovered in the Uinta and Piceance basins; however, there have been no fields discovered in the Eagle structural basin. The lack of exploration success in the Eagle Basin is attributed to very thermal maturity levels in source rocks (Johnson and Nuccio, 1993) and the generally poor quality of reservoirs, and although gas might be present, the expected volume is small. The Uinta Basin of Utah is about 120 mi long and is bounded on the west by the thrust belt and on the east by the Douglas Creek Arch. It is nearly 100 mi wide and bounded on the north side by the Uinta Mountains Uplift.

This is one of many related papers that were included in the 1981 NMGS Fall Field Conference Guidebook. Annual NMGS Fall Field Conference Guidebooks Every fall since 1950, the New Mexico Geological Society (NMGS) has held an annual Fall Field Conference that explores some region of New Mexico (or surrounding states). Always well attended, these conferences provide a guidebook to participants. Besides detailed road logs, the guidebooks contain many well written, edited, and peer-reviewed geoscience papers. These books have set the national standard for geologic guidebooks and are an essential geologic reference for anyone working in or around New Mexico. Free Downloads NMGS has decided to make peer-reviewed papers from our Fall Field Conference guidebooks available for free download. Non-members will have access to guidebook papers two years after publication. Members have access to all papers. This is in keeping with our mission of promoting interest, research, and cooperation regarding geology in New Mexico. However, guidebook sales represent a significant proportion of our operating budget. Therefore, only research papers are available for download. Road logs, mini-papers, maps, stratigraphic charts, and other selected content are available only in the printed guidebooks.
