Evidence for a correlation between total lead concentrations in soils and the presence of geological faults
The emission of radon gas in regions of geological faults, during the radioactive decay of uranium and thorium, results in the formation of lead isotopes 210Pb, 208Pb, 207Pb and 206Pb. As a consequence, the lead contamination ...
Submarine earthquake rupture, active faulting and volcanism along the major Liquiñe-Ofqui Fault Zone and implications for seismic hazard assessment in the Patagonian Andes
The Liquiñe-Ofqui fault zone (LOFZ) in the Patagonian Andes is an active major transpressional intra-arc fault system along which Quaternary faulting and volcanism develop. Subaerial and submarine geomorphologic and structural ...
The use of apatite fission track thermochronology to constrain fault movements and sedimentary basin evolution in northeastern Brazil
(Elsevier B.V., 2005-12-01)
An apatite fission track study of crystalline rocks underlying sedimentary basins in northeastern Brazil indicate that crustal blocks that occur on opposite sides of a geological fault experienced different thermal histories. ...

The geometry of the active strike-slip El Tigre Fault, Precordillera of San Juan, Central–Western Argentina: integrating resistivity surveys with structural and geomorphological data
The geometry and related geomorphological features of the right-lateral strike-slip El Tigre Fault, one of the main morphostructural discontinuities in the Central– Western Precordillera of Argentina, were investigated. ...
Tectonic styles and crustal shortening of the Central Andes “Pampean” flat-slab segment in northern Chile (27–29°S)
The Andean orogenic belt, located in the Central Andes "Pampean flat-slab" segment in northern Chile (27-29 degrees S), is composed of two major tectonic regions: the Coastal Cordillera and the Frontal Cordillera. To ...
States of stress and slip partitioning in a continental scale strike-slip duplex: tectonic and magmatic implications by means of finite element modeling
Orogenic belts at oblique convergent subduction margins accommodate deformation in several trench parallel domains, one of which is the magmatic arc, commonly regarded as taking up the margin-parallel, strike-slip component. ...
Control of strike-slip fault on dyke emplacement and morphology
(Geological Society of London, 2016-07)
Strike-slip faults are commonly assumed to influence magma transport and emplacement in the Earth’s crust. However, direct observations of magma conduits within strike-slip faults are lacking. Here we provide some of the ...
