U.S. Geological Survey Scientific Investigations Map 3131

Bedrock Geologic Map of the Seward Peninsula, Alaska, and Accompanying Conodont Data

By Alison B. Till, Julie A. Dumoulin, Melanie B. Werdon, and Heather A. Bleick

Introduction

This 1:500,000-scale geologic map depicts the bedrock geology of Seward Peninsula, western Alaska, on the North American side of the Bering Strait. The map encompasses all of the Teller, Nome, Solomon, and Bendeleben 1:250,000-scale quadrangles, and parts of the Shishmaref, Kotzebue, Candle, and Norton Bay 1:250,000-scale quadrangles (sh. 1; sh. 2).

The geologic map is presented on Sheet 1. The pamphlet includes an introductory text, detailed unit descriptions, tables of geochronologic data, and an appendix containing conodont (microfossil) data and a text explaining those data. Sheet 2 shows metamorphic and tectonic units, conodont color alteration indices, key metamorphic minerals, and locations of geochronology samples listed in the pamphlet.

The map area covers 74,000 km², an area slightly larger than West Virginia or Ireland.
