ECONOMIC GEOLOGY OF THE SAN BERNARDINO MOUNTAINS, CALIFORNIA
<p>The San Bernardino Mountains are well known for their rich mining history, especially, gold in the mid-1800s and the current mining of one of the world’s largest deposits of high purity limestone. The purpose of this study was to compile new, current, and historical data of the major economic …

Characterizing the deformation history of the southern Mina Deflection: field and structural studies in the Huntoon Mountains, California-Nevada
… studies in the Huntoon Mountain area (HMA), California-Nevada document the volcanic and deformation histories across the south-central Mina Deflection (MD). Our work allows us to (a) test whether present-day GPS predicted sinistral slip rates are the same as geologic slip rates in the …

The geology and geochemistry of volcanic rocks in the Lava Mountains, California: Implications for Miocene development of the Garlock Fault
The Lava Mountains are located in the Mojave Desert, southern California along the Garlock Fault, a major continental strike-slip fault that separates the southwestern Basin and Range to the north from the Mojave block to the south. Chemical similar dacitic lava and pyroclastic flows erupted from …

Geologic mapping and zircon (U-Th)/He thermochronology of the Avawatz Mountains, California; Implications for the eastern terminus of the Garlock fault
The Avawatz Mountains are located at the eastern tip of the left-slip Garlock fault where the fault intersects the NW-striking right-slip Southern Death Valley fault (SDVF). The Avawatz Mountains were constructed via late Cenozoic contractional deformation involving active thrust and/or …

Structural and petrologic aspects of the emplacement of granitoid plutons : case studies from the western margin of the Joshua Flat-Beer Creek-Pluton (White-Inyo Mountains, California) and the Flasergranitoid zone (Odenwald, Germany)
… Flat-Beer Creek Pluton (JBP) in the White-Inyo-Mountains, California, is part of the Inyo batholith and was emplaced 180-160 Ma ago. The intrusion consists of three phases. Field relations, remote sensing data and major element geochemistry suggest an intrusion sequence Marble Canyon Diorite --> …

Kinematics and timing of the Pinto shear zone, New York Mountains, northeastern Mojave Desert, California
New studies of the Pinto shear zone, New York Mountains, California, improve our understanding of the importance of Mesozoic extension in Mojave Desert and also contribute to the growing body of evidence for syncontractional extension in the Mesozoic Sevier orogen. The Pinto shear zone has a …

Paragenesis, fluid origin, and thermal history of a low-sulfidation epithermal gold-silver system
… breccias +/- Au in the southern Castle Mountains, California were collected from four different zones within and up to 5 km outside the mine area in order to construct a paragenesis, interpret fluid origin, describe the thermal history, and examine fluid inclusion gas compositions as an …
