      It is located along the trace of the Vincent Thrust in the San Gabriel Mountains of southern California. Mineralization occurs in the northeast-striking, 15? to 30? northwest-dipping Vincent Thrust zone. The thrust forms the contact between upper plate San Gabriel Gneiss (Precambrian) and lower plate Pelona Schist. (Precambrian or Mesozoic?). More than potassium-argon apparent ages on minerals from crystalline rocks, chiefly from the San Bernardino and eastern San Gabriel Mountains and the southern Mojave Desert, define an area greater t km 2 in which the potassium-argon isotopic systematics have been highly disturbed.

the eastern San Gabriel Mountains (Premo et al., ; personal commun. with J. Nourse, in Hoyt et al., 20 18). The Proterozoic basement of southern California is intruded by numerous.

The evidence for such a claim stems from the relation between the present-day Banning and San Gabriel faults with an ancient thrust fault known as the Vincent Thrust.

This thrust fault appears both in the San Gabriel Mountains and the San Bernardino Mountains, near each of the supposed sections of the ancestral San Gabriel fault in such a way. The east-central San Gabriel Mountains reveal a folded stack of crystalline sheets constituting the lower and upper plates of the latest Cretaceous-Paleocene Vincent thrust (Figs.

2 and 3). shown in Figure 4. The San Gabriel Mountains, as outlined above, will be designated tectonically as the “San Gabriel uplift” (Dibblee, ). The San Gabriel Mountains uplift is highest in its eastern part, where it narrows and wedges out eastward into an alluvial plain.

This part includes its highest point, Mount San Antonio. The basement rocks of the eastern San Gabriel Mountains have been the subject of many studies in the last several decades. The Pelona Schist in this region is disrupted by both NE-striking and NW-striking fault systems that intersect one another.

The nature of intersections of such faults in the eastern San Gabriel Mountains is enigmatic. Does. The San Gabriel Mountains (SGM) is an east–west trending range formed from the uplift of the basement rocks along the southwest side of the ‘big bend’ portion of the SAF ().Recent fission track and U–Th/He analysis by Blythe et al.

() suggest that the high elevations (–3 km) of the SGM are largely uplifted within the last 7 Ma, with differential uplift patterns (including rate.

This age assignment suggests that the Mill Canyon mylonites are correlative with the Vincent thrust mylonites in the eastern San Gabriel Mountains (Jacobson et al., ). The gneissic, granitic, and sedimentary rocks of the San Gabriel Mountains lie within the upper plate of the Vincent thrust (e.g., Ehlig, ).

The lower plate is composed of Pelona Schist, which is predominantly meta-arkose (Haxel and Dillon, ; Ehlig, ; Jacobson et al., ).

This relationship is exposed in a structural window in the.
