Description

It is becoming increasingly clear that Arizona's.Basin and Range Province contains an abundance of low-angle tectonic phenomena that are diverse in space, time and tectonic significant. It is the purpose of this field trip to examine a representative sample of·these tectonic phenomena, emphasizing their geometry, timing, kinematics and regional significance to Arizona's tectonic and mineral-deposit framework (Figure 1). With this goal in mind we will discuss from a distance the complex low-angle fault, mylonitic, and plutonic terranes in the eastern Tortolita,Santa Catalina, and Picacho Mountains (DAY 1: STOPS 1 AND 2). These mountains contain Laramide through mid-Tertiary mylonitic phenomena that geologists have variously related to early Laramide northeast-vergent thrusting, late Laramide southwest-vergent thrusting and two-mica granite magmatism, mid-Tertiary regional crustal extension. These stops will be primarily lead by Stan Keith.
