Structure, emplacement mechanism and magma-flow significance of igneous fingers – Implications for sill emplacement in sedimentary basins
(Pergamon-Elsevier Science Ltd, 2019-07)
Field and seismic observations show that numerous sills exhibit lobate morphologies. Each lobe corresponds to a distinct igneous segment exhibiting a finger-like shape, the long axis of which is commonly interpreted as a ...
Igneous sill and finger emplacement mechanism in shale-dominated formations: a field study at Cuesta del Chihuido, Neuquén Basin, Argentina
(Geological Society of London, 2016-12)
Seismic reflection data and field observations have revealed the presence of voluminous igneous sill complexes emplaced into organic-rich shale formations in sedimentary basins worldwide. Damage and structures associated ...
Implications of longitudinal ridges for the mechanics of ice-free long runout landslides
(2021)
The emplacement mechanisms of long runout landslides across the Solar System and the formation mechanisms of longitudinal ridges associated with their deposits remain subjects of debate. The similarity of longitudinal ...
A view from the roof: Magmatic stoping in the shallow crust, Chita pluton, Argentina
(Pergamon-Elsevier Science Ltd, 2003-07)
Nearly 2 km of vertical relief and exposure of continuous pluton roof-wall corners around the Chita pluton, northwest Argentina, provides constraints on the 3-D host rock displacement field attending magma emplacement in ...
Brasiliano crustal extension and emplacement fabrics of the mangerite-charnockite pluton of Umarizal, North-east Brazil
(Elsevier Science BvAmsterdamHolanda, 1998)
Thermal evolution of upper crustal magmatic systems from the Sierra de Velasco, NW Argentina
(Pergamon-Elsevier Science Ltd, 2019-01)
Detailed mapping of the Huaco intrusive Complex in NW Argentina documents a shift in the emplacement style of successive magma additions in an upper crustal environment as the system evolves thermally. The units of the ...
The Ordovician Las Chacritas pluton (Sierra de Humaya, NW Argentina): origin and emplacement triggered by lateral shortening and magmatic stoping at mid-crustal level
(Springer Verlag Berlín, 2015-04)
Field relationships and structural studies combined with in situ U-Th-Pb dating of monazite from Las Chacritas pluton (LCP), Sierra de Humaya, provide insight into the emplacement of peraluminous magmas triggered by lateral ...
Characteristics and emplacement mechanisms of the Coranzulí ignimbrites (Central Andes)
(Elsevier Science, 2020-07-15)
We present a detailed stratigraphy of the Coranzulí caldera-forming deposits. This caldera, located in the Altiplano-Puna Volcanic Complex (Central Andes), generated four ignimbrite deposits with similar field characteristics ...
