| Many sediment-hosted gold deposits occur along linear trends in the Great
Basin.
The distribution and genesis of these deposits in the Great Basin is not
fully
understood. In general, most models agree that regional structures played
an
important role in the spatial distribution of these deposits (e.g. Arehart
and
others, 1993; Ilchik and Barton, 1997; Radtke, 1985; Shawe, 1991; Sillitoe
and
Bonham, 1990; Tosdal, 1998). To investigate crustal structures that may
be
related to the genesis of gold deposits in the Great Basin, a regional
south-north profile of magnetotelluric (MT) soundings was acquired in 2003.
Resistivity modeling of the MT data can be used to investigate buried structures
or sutures that may have influenced subsequent tectonism, sedimentation,
and
regional fluid flow. The goal of this survey is to infer the location of
the
Archean/Proterozoic suture zone in east-central Tooele County, Utah. The
purpose of this report is to release the MT sounding data; no interpretation
of
the data is included. |
