Map showing general chemical quality of surface water in the Richfield Quadrangle, Utah

This is one of a series of maps that describe the geology and related natural resources of the Richfield 2° quadrangle, Utah. The purpose of this map is to show the general chemical quality of surface water in the area by ranges of dissolved-solids concentrations.Data used to compile this map were collected by the U.S. Geological Survey in cooperation with the Utah Department of Natural Resources,

Map showing the distribution of minerals in the heavy-mineral concentrate of stream sediments in the Sierra Ancha Wilderness and Salome Study Area, Gila County, Arizona

Reconnaissance geochemical and mineralogical sampling was done in the Sierra Ancha Wilderness and Salome Study Area during April and May 1978. This map shows the distribution of chalcopyrite, florite, galena, scheelite, and lead-rich iron oxides in the nonmagnetic fraction of the heavy-mineral concentrate of stream sediment samples collected during the reconnaissance study.

Map showing the Elko crater field, Elko County, Nevada

The Elko crater field consists of two arrays of rimmed craters in the valleys of Dorsey, Susie, and McClellan Creeks, 30 to 50 km north of Elko, Nevada. In the principal array, more the 165 craters are scattered irregularly in an area 3 km wide and 20 km long. Most of the the craters are circular but some, formed by overlap, are oval or irregular. They range from 5 m to 250 m in diameter and the r

Map showing the late preglacial (Teays-age) course and pre-Illinoian deposits of the Licking River in north-central Kentucky

A considerable body of writing exists on the geological evolution of the Ohio River and some of its principal tributaries, among which is the Licking River of Kentucky (fig. 1).
