The Sierra Nevada and the Klamath Mountains were the result of continental magmatic arc and then oceanic arc accretion during the Nevadan Orogeny between 155 and 145 Ma. [ 12 ] [ 2 ] [ 1 ] At nearly the same time the Eastern Belt of the Sierra Nevada was forming, the Western Hayfork Terrane of the Klamath Mountains was being constructed.
In the United States, Mother Lode is most famously the name given to a long alignment of hard-rock gold deposits stretching northwest-southeast in the Sierra Nevada of California, [2] bounded on the east by the Melones Fault Zone. [3] It was discovered in the early 1850s, during the California gold rush.
In Nevada's recent geologic past, tectonic changes have created normal faults and creating the basin and range horst and graben terrain. Thinning of the upper crust caused deeper, highly metamorphosed rock masses to rise to the surface, where it is overlain by younger faulted and domed rocks.
The Pyramid Lake Fault Zone is an active right lateral-moving (dextral) geologic fault located in western Nevada. It is considered an integral part of the Walker Lane.. The fault zone extends to the southeast from Pyramid Lake roughly parallel to the course of the Truckee River between the Truckee Range to the northeast and the Pah Rah Range to the southwest.

The north-northwest end of the Walker Lane is between Pyramid Lake in Nevada and California's Lassen Peak [1] [2] where the Honey Lake Fault Zone, the Warm Springs Valley Fault, and the Pyramid Lake Fault Zone [3] meet the transverse tectonic zone forming the southern boundary of the Modoc Plateau and Columbia Plateau provinces.
The Rescue Lineament-Bear Mountains fault zone, in eastern California, is a series of co-axial faults located in the western foothills of the Sierra Nevada (mountain range). [ 1 ] The fault zone represents an ancient suture, the boundary where an ancient oceanic crustal block known as an exotic terrane , named by geologists the Smartville Block ...
The Independence Valley fault system is a group of interrelated normal faults located in northeastern Nevada in the United States. The fault system is characteristic of faulting throughout the Great Basin region.
