Contrasting styles of superposed deformation in the southernmost Andes

Article Abstract:

Geophysical and geologic data from the southern end of the Magallanes foreland basin were investigated in the discussion of deformation patterns and regional trends affecting the development of the unusual geologic features in the Andes. Over 100 kilometers of multichannel seismic reflection data were analyzed and synthesized with results from structural mapping, satellite gravity data and published seismic data. The results suggested that the southern rim of the Magallanes basin was influenced by four contradicting styles of superposed deformation.

Kinematics, topography, shortening, and extrusion in the India-Eurasia collision

Article Abstract:

A study was conducted to analyze the partitioning problem between shortening and extrusion in the India-Eurasia collision. Measurement of the amount of shortening predicted from India's kinematic motion with respect to Eurasia is computed by reconstructing collision time to set limits on possible surface loss within both regions. Results show that lower crust transfer to the mantle and lateral extrusion must have caused a fractional part of total shortening amount between the subject areas.

Systematic analyses of the large-scale topography and structure across the Dead Sea Rift

Article Abstract:

A study analyzes the large-scale topography and structure over the central part of the Dead Sea Rift (DSR) between lake Kinneret and the Gulf of Elat, and the regional morphology, paleomorphology, geological history and crustal structure is described. It is suggested that the asymmetric large-scale topography and structure reflects a wide half-graben and a regional uplift.
