UNDERSTANDING BLOCK ROTATION ALONG STRIKE-SLIP FAULT ZONES IN YUNNAN (CHINA): PALEOMAGNETIC AND STRUCTURAL APPROACH
I dati raccolti durante i tre anni di attività di Dottorato di Ricerca riguardano il paleomagnetismo di rocce sedimentarie e vulcaniche affioranti lungo due importanti zone di taglio che caratterizzano la provincia dello Yunnan (Cina): la faglia Gaoligong e la faglia del Red River. Durante il …

Multidisciplinary investigations of the Chaman strike-slip fault along the western Indo-Asian collision boundary, Pakistan
The Chaman left-lateral strike-slip fault bounds the collision zone between Indian and Eurasian plates at the western end of the Himalayan-Tibetan orogen and connects the Makran subduction zone to the Himalayan convergence zone. This western collision boundary received extensive magmatism as …

Structural Analysis of Ernst Tinaja Canyon Focusing on Strike-Slip Faulting and Folding, Big Bend National Park, Texas
… study area including folds, normal and thrust faults and a previously unmapped, large dextral strike-slip fault, with associated negative flower structure. Theories for the mechanisms and kinematics of deformation are discussed and a model is presented for the overall tectonic history of the …

The geology of the Waterberg group in the southern Portion of the Waterberg basin
… Ma old. The depository evolved as a continental, fault-bounded basin in the northern part of the Kaapvaal craton. The basin is bounded in the south by the Murchison lineament and in the north by the southern part of the Pal al a shear zone. The Murchison lineament is interpreted to be a …

Integrated, Basin-To-Reservoir Scale, Geologic and Geophysical Studies of a Carbonate-Hosted, Hydrocarbon Reservoir of the La Vela Basin, Northwestern Venezuela
… Caribbean arc along the Adícora-Pueblo Nuevo strike-slip fault system bounding the northern edge of the LVB. Basement in the LVB consists of three types of allochtonous, metamorphosed, basement of Neoproterozoic, Permian, and Cretaceous age. The differences between the carbonates that develop …

Models of interseismic deformation with an analytic framework for the inclusion of general linear viscoelastic rheologies
… using two-dimensional models of a vertical strike-slip fault in an elastic layer over a viscoelastic region. Central to this, I derive an analytic framework to include general linear viscoelastic theologies into models of interseismic deformation. Models with multi-viscous viscoelastic …

The geology and geochemistry of volcanic rocks in the Lava Mountains, California: Implications for Miocene development of the Garlock Fault
… 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 the 9-km diameter Western Lava Mountains …

Soil-pipeline interaction in unsaturated soils
… to simulate the soil-pipeline interaction under strike-slip fault movements. The finite element model was first validated by comparing the computed results to the data produced from a full scale experiment carried out at CU. The analysis was then further extended by varying the initial conditions …

Numerical simulation of selected geologic processes based on Discrete Element Method
… in releasing sidestep systems with pure strike-slip, transtensional, and transpressional master faults, respectively. In each system, three typical models including 30° underlapping, 90° non-overlapping, and 150° overlapping releasing sidesteps are chosen. The modeling results are …

The Box Ankle and Ocmulgee shear zones of central Georgia: a study of geochemical response to Southern Appalachian deformation events
… Is bounded on the east by the Box Ankle thrust fault which juxtaposes basement lithologies from hanging wall paragneiss, schist, and metavolcanic rocks of the Piedmont terrane. The Ocmulgee strike-slip fault separates Piedmont Terrane rocks from Avalon Terrane lithologies to the south and east …

Geology of the Northern Alto Relex Area, Big Bend National Park, Brewster County, Texas
… is a prominent, near vertical, ~1000 foot-high fault-line scarp. Cretaceous rocks in the area were folded and faulted by Laramide compression, intruded by Tertiary sills and overprinted by high-angle normal faults from Basin and Range extension. During the Laramide Orogeny and Basin and Range …

Stratigraphy and Structure of the Miocene "Esmeralda" Formation in Stewart Valley, Mineral County, Nevada
… Range was uplifted along the Battle's Well Fault. However, this fault is mainly a strike-slip fault associated with Walker Lane and most of the displacement on the fault was horizontal.</p> <p>During most of the Miocene the valley was tectonically stable and the main drainage was south. The …
