The Uinta - Gold Hill Trend: An Economically Important Lineament

A. J. Erickson, Jr.

Abstract

Stretching across the Middle Rocky Mountain Province in northwestern Colorado and eastern Utah and into the Basin and Range Province of central and western Utah is a linear crustal feature active during a considerable portion of geologic time. This linear feature, the Uinta-Gold Hill Mineral Trend, is the northernmost of several easterly trends in Utah and has been the site of varied geologic processes since at least early Paleozoic time.

The trend has been the site of uplift as early as Ordovician time, again in Devonian, and more recently during the Tertiary Laramide orogeny.

The trend is marked by a pronounced narrow aeromagnetic high and several individual smaller highs. Numerous intrusive bodies are present at various points along the aeromagnetic high. Associated with the intrusives are the major mining districts of Park City and Bingham (West Mountain) as well as the smaller districts of Big and Little Cottonwood, Stockton, Gold Hill and several others.

The trend has been pointed out by various authors, at various times in the past. The present paper summarizes the features associated with the trend and concepts concerning the trend.
