Mesoproterozoic tectonothermal development of southwestern Sweden : new age constraints using field relationships and U-Pb geochronology
The Atran terrane of southwestern Sweden is a Mesoproterozoic, polydeformed terrane and a product of crustal growth westward away from an Archean core. Both Gothian (Labradorian) and Sveconorwegian (Grenvillian) deformations ...
Structural styles of the Andean foothills, Putumayo Basin, Colombia
Interpretation of seismic profiles, earthquake fault-plane solutions, radar images, and geometry of structures suggests that two different structural styles are viable alternatives for the Putumayo basin in Colombia. An ...
Hydrogeological investigations at Diamond Y Springs and surrounding area, Pecos County, Texas
This study presents the results of local hydrogeologic investigations at Diamond Y Springs and vicinity, a 660 mi² (1710 km² ) area of north-central Pecos County, Texas. The data confirm the hypothesis of Rustler aquifer ...
Evolution of Neogene contractional growth structures, southern Gulf of Mexico
Structural analysis of four contractional growth structures in the Southern Neogene Belt of Mexico was undertaken to test conceptual models of folding mechanisms for contractional deformation and to obtain structural ...
Veins and alteration envelopes in the Grasberg Igneous Complex, Gunung Bijih (Ertsberg) District, Irian Jaya, Indonesia
The Grasberg Igneous Complex (GIC) consists of three main phases of igneous activity: the Dalam Igneous Complex, the Main Grasberg Intrusion, and the Kali Intrusion. Each contains veins revealing a history of fluid flow ...
