time resolved construction of a bimodal Laccolith torres del paine patagonia
Earth and Planetary Science Letters, 2012Co-Authors: Julien Leuthold, Lukas P. Baumgartner, Benita Putlitz, Maria Ovtcharova, Othmar Muntener, Urs SchalteggerAbstract:Abstract Granitic and mafic magma pulses were sequentially accreted in the spectacularly exposed shallow crustal Torres del Paine Laccolith, in southern Patagonia. This 12.5 Ma pluton forms a composite intrusion with a subvertical feeding system in the west and a Laccolith in the east. A key unknown in the formation of sill complexes is how individual magma pulses are assembled over time and the geometry and localization of their feeding system. High resolution zircon CA-ID-TIMS U–Pb dating shows that the Laccolith grew first by under-accretion of granitic sills over 90 ± 30 ka, linked to a ‘sheet-like’ feeding system, followed by underplating of mafic sills after ~ 20 ka of quiescence. In the mafic sills complex, individual sills were injected by over-accretion during 41 ± 11 ka. Our data show that successive granitic and mafic magmas emplacement generated a volume of ~ 88 km3 in 162 ± 11 ka.

High resolution zircon CA-ID-TIMS U-Pb dating shows that the Laccolith grew first by under-accretion of granitic sills over 90 +/- 30 ka, linked to a 'sheet-like' feeding system, followed by underplating of mafic sills after similar to 20 ka of quiescence. In the mafic sills complex, individual sills were injected by over-accretion during 41 +/- 11 ka. Our data show that successive granitic and mafic magmas emplacement generated a volume of similar to 88 km(3) in 162 +/- 11 ka. (C) 2012 Elsevier B.V. All rights reserved

Incremental growth of the Patagonian Torres del Paine Laccolith over 90 k.y
Geology, 2008Co-Authors: Jürgen Michel, Lukas P. Baumgartner, Benita Putlitz, Urs Schaltegger, Maria OvtcharovaAbstract:The Miocene Paine Granite in the Torres del Paine Intrusive Complex, southern Chile, is an extraordinary example of an upper crustal mafic and granitic intrusion. The granite intruded as a series of three sheets, each one underplating the previous sheet along the top of the basal Paine Mafic Complex. High-precision U/Pb geochronology on single zircons using isotope dilution-thermal ionization mass spectrometry yields distinct ages of 12.59 +/- 0.02 Ma and 12.50 +/- 0.02 Ma, respectively, for the first and last sheet of the Laccolith. This age relationship is consistent with field observations. The zircon ages define a time frame of 90 +/- 40 k.y. for the emplacement of a >2000-m-thick granite laccollith. These precise U-Pb zircon ages permit identification of the pulses in a 20 k.y. range. The data obtained for the Paine Granite fill the gap between 100 k.y. and 100-1000 yr pulses described in the literature for crustal magma chambers
