Tectonic Deformation of a Lacustrine Mudstone at Soda Lake Geothermal Field, Western Nevada, USA, from 3D Seismic Interpretation

چکیده
The transition between the two structural regimes of the Walker Lane and the Basin and Range allows for complex transtensional fault interactions. NWtrending dextral shear in the Walker Lane and WNW extension in the northern Great Basin imparts enhanced extension and pull-apart basins that bring about structural controls for geothermal systems. The Carson Sink is the surface expression of this complex interaction of shear and extensional forces that cause crustal block rotation. This study investigates this tectonic shift in the Carson Sink using the fault offset of a paleo-planer lacustrine mudstone in 3D seismic at the Soda Lake Geothermal Field. With few mapped intrabasin faults, this gives a unique view into fault offsets inside this basin. Abstract

Anelastic properties beneath the Niigata–Kobe Tectonic Zone, Japan
We estimate the three-dimensional (3D) P-wave attenuation structure beneath the Niigata–Kobe Tectonic Zone (NKTZ), central Japan, using high-quality waveform data from a large number of stations. The obtained results confirm the segmentation of the NKTZ into three regions, as suggested by 3D seismic velocity models, and reveal characteristic structures related to surface deformation, shallow su...

[1] We have estimated patterns and rates of crustal movement across 800 km of the Basin and Range at 39 north latitude with Global Positioning System surveys in 1992, 1996, 1998, and 2002. The total rate of motion tangent to the small circle around the PacificNorth America pole of rotation is 10.4 ± 1.0 mm/yr, and motion normal to this small circle is 3.9 ± 0.9 mm/yr compared to the east end of...

Fish Lake Valley, in Esmeralda County, Nevada, sits at the southern end of the Mina Deflection where the very active Death Valley-Furnace Creek-Fish Lake Valley fault system makes a right step to transfer slip northward into the Walker Lane. Northern Fish Lake Valley has been pulling part since ca. 6 Ma, primarily along the Emigrant Peak normal fault zone (Stockli et al., 2003). Elevated tecton...
متن کاملNorthwest Basin and Range tectonic deformation observed with the Global Positioning System , 1999 – 2003
[1] We use geodetic velocities obtained with the Global Positioning System (GPS) to quantify tectonic deformation of the northwest Basin and Range province of the western United States. The results are based on GPS data collected in 1999 and 2003 across five new quasi-linear networks in northern Nevada, northeast California, and southeast Oregon. The velocities show 3 mm/yr westward movement of...

The western segment of the Churchill Province of Canada, west of Hudson Bay, was divided by Hoffman (1988) into the Archean Rae and Hearne domains separated by the Snowbird Tectonic Zone (STZ) (Fig. 1), defined on the basis of potential field data. The Hearne domain has been further subdivided into the northern Hearne and southern Hearne subdomains (Davis et al., this volume). There is little d...
