چکیده
The Lahontan Mountains quadrangle is located 11 km east of Fallon, Nevada at the southeastern margin of the Carson Sink (Fig. 1). Principal physiographic features include the Lahontan Mountains, collectively consisting of Sehoo, Eetza, Salt Wells, and Rainbow mountains. This quadrangle is part of the greater Lake Lahontan area that in part occupied the southern Carson Desert, previously mapped by Roger B. Morrison between 1947 and 1950. The products of Morrison’s studies are contained in the 1964 U.S. Geological Survey Professional Paper 401, “Lake Lahontan: Geology of the southern Carson Desert, Nevada”, which stands as a seminal study on late Pleistocene Lake Lahontan in western Nevada, and provides the fundamental basis for all subsequent studies of Lake Lahontan geology, including this one. The subtitle to Professional Paper 401 accurately describes the significance of Morrison’s contribution to the field of Quaternary geology in the Great Basin:

INTRODUCTION Precambrian rocks in the Tusas Mountains range from nearly monomineralic quartzite, in which the principal result of metamorphism has been simple recrystallization, through locally metasomatized schist and gneiss profoundly modified by potash-rich fluids during the intrusion of pegmatite. Texturally, the rocks range from schist and phyllite containing penetrative and pervasive clea...

Qs Sand Wind-blown sand blankets a number of areas in the western part of the quadrangle. These well-sorted, mediumto fine-grained quartzose sands are commonly deposited on the east to northeast sides of hills but may extend across some flat areas. The sands are uncemented and loose but most are well stabilized by vegetation, locally including trees. The sands are usually white to tan but local...
