Structural geology of South Hadhramaut area Yemen Republic
The northern margin of the Gulf of Aden has a long history of extension from the Cambrian to the present. The dominant structures are related to Oligo-Miocene rifting in the early stages of development of the Gulf of Aden and they overprint Palaeozoic and Mesozoic structures. An area of 170 km by …

Structural Geology of the Caddo Gap Area, Ouachita Mountains, Arkansas
… mapping focused on delineating stratigraphic and structural relationships in the southern part of the quadrangle to improve existing reconnaissance-scale maps of the area. New structures were discovered that provide further information about the structural evolution of the Ouachita fold and thrust …

Structural geology of the southern Silurian hills, San Bernardino County, Calif
In the southern part of the Silurian Hills, seven lithologic units are delineated. They are an earlier Precambrian gneiss complex, the later Precambrian Pahrump Group, a Precambrian (?) metasedimentary complex, a Precambrian (?) metadioritic and metasedimentary complex, the Riggs Formation, basic …

Structural geology of the Gass Peak area Las Vegas Range, Nevada
… developed independently after being separated. Structural evidence indicated that displacement on the Gass Peak Thrust occurred before movement along the Las Vegas Valley Shear Zone. There is little evidence in the mapped area for Tertiary block faulting.

Structural geology, metamorphism and origin of the Kanmantoo Copper deposit, South Australia
On the basis of the present study it is concluded that there is no firm evidence that the bulk of the mineralisation is pre-metamorphic, although the possibility has not been excluded.

The structural geology of the Southern Norwegian Caledonides in the Oslo Graben and Sparagmite region
In order to construct the most continuous balanced cross-section from undeformed foreland to higher thrust sheets in the southern Caledonides of Norway, selected areas of Cambro-Silurian rocks were mapped in the Oslo Graben. Undeformed rocks are only present in the southern part of the Oslo Graben …

Middle Ordovician (Chazyan) conodont biostratigraphy and structural geology of the McMullin Syncline, Smyth County, Virginia
The McMullin syncline is located in Smyth County within the Valley and Ridge Province of southwestern Virginia. The syncline lies in a recess along the northern periphery of the Seven Springs-Pulaski thrust and consists of seven small fault blocks which are complicated by three generations of …

Structural geology and geochemistry of sedimentary rock-hosted gold in the eastern Nadaleen Trend, Yukon Territory, Canada
… are consistently NNE-vergent. This change in structural style suggests that NNE-directed transport in the rocks to the west was obstructed at the latitude of the eastern Nadaleen Trend while transport in the east was unobstructed. Potential causes for the obstruction include rheological …

Structural geology and stratigraphy at the junction of the curral anticline and the moeda syncline, Quadrilatero Ferrifero, Minas Gerais, Brazil
In the map area the rocks are divided into two large subdivisions: the Archaean Nova Lima greenstone and the Bonfim granitoid gneisses, and the overlying Proterozoic Minas metasedimentary and metavolcanic rocks, including abundant iron formation. These groups are separated by a major unconformity. …
