Importance of Predecessor Basin History on the Sedimentary Fill of A
EAGE Basin Research (2010) 22, 640–658, doi: 10.1111/j.1365-2117.2009.00443.x Importance of predecessor basin history on the sedimentary fill of a retroarc foreland basin: provenance analysis of the Cretaceous Magallanes basin, Chile (50^521S) B.

Covaultn nDepartment of Geological & Environmental Sciences, Stanford University, Stanford, CA, USA wChevron EnergyTechnology Company, Clastic Stratigraphy R&D, San Ramon, CA, USA zDepartment of Geoscience, University of Calgary,Calgary,AB, Canada ABSTRACT An integrated provenance analysis of the Upper Cretaceous Magallanes retroarc foreland basin of southern Chile (501300^521S) provides new constraints on source area evolution, regional patterns of sediment dispersal and depositional age. Over 450 new single-grain detrital-zircon U-Pb ages, which are integrated with sandstone petrographic and mudstone geochemical data, provide a comprehensive detrital record of the northern Magallanes foreland basin- ¢lling succession (44000- m-thick). Prominent peaks in detrital-zircon age distribution among the Punta Barrosa, CerroToro, TresPasos andDoroteaFormations indicate thatthe incorporation and exhumation ofUpperJurassic igneous rocks (ca.147^155Ma) into the Andean fold-thrust belt was established in the Santonian (ca. 85 Ma) andwas a signi¢cant source of detritus to the basin by the Maastrichtian (ca.70 Ma). Sandstone compositional trends indicate an increase in volcanic and volcaniclastic grains upward through the basin ¢ll corroborating the interpretation of an unroo¢ng sequence. Detrital-zircon ages indicate that the Magallanes foredeep received young arc-derived detritus throughout its ca. 20 m.y.¢lling history,constraining the timing of basin- ¢lling phases previously based only on biostratigraphy. -

Sedimentary basins evolved in a wide range of Foreland basins structural settings on both flanks of the Andean magmatic arc, with strong signatures of retroarc crustal Orogeny shortening, flexure, and rapid accumulation in long-lived foreland and hinterland basins.

Along-Strike Variation in Structural Styles and Hydrocarbon Occurrences, Subandean Fold-And-Thrust Belt and Inner Foreland, Colombia to Argentina
The Geological Society of America Memoir 212 2015 Along-strike variation in structural styles and hydrocarbon occurrences, Subandean fold-and-thrust belt and inner foreland, Colombia to Argentina Michael F. McGroder Richard O. Lease* David M. Pearson† ExxonMobil Upstream Research Company, Houston, Texas 77252, USA ABSTRACT The approximately N-S–trending Andean retroarc fold-and-thrust belt is the locus of up to 300 km of Cenozoic shortening at the convergent plate boundary where the Nazca plate subducts beneath South America. Inherited pre-Cenozoic differences in the overriding plate are largely responsible for the highly segmented distribution of hydrocarbon resources in the fold-and-thrust belt. We use an ~7500-km-long, orogen- parallel (“strike”) structural cross section drawn near the eastern terminus of the fold belt between the Colombia-Venezuela border and the south end of the Neuquén Basin, Argentina, to illustrate the control these inherited crustal elements have on structural styles and the distribution of petroleum resources. Three pre-Andean tectonic events are chiefl y responsible for segmentation of sub- basins along the trend. First, the Late Ordovician “Ocloyic” tectonic event, recording terrane accretion from the southwest onto the margin of South America (present-day northern Argentina and Chile), resulted in the formation of a NNW-trending crustal welt oriented obliquely to the modern-day Andes. This paleohigh infl uenced the dis- tribution of multiple petroleum system elements in post-Ordovician time. Second, the mid-Carboniferous “Chañic” event was a less profound event that created mod- est structural relief. Basin segmentation and localized structural collapse during this period set the stage for deposition of important Carboniferous and Permian source rocks in the Madre de Dios and Ucayali Basins in Peru. -

Detrital Thermochronologic Record of Burial Heating and Sediment Recycling in the Magallanes Foreland Basin, Patagonian Andes Julie C

Fosdick,* Marty Grove,† Stephan A. Graham,† Jeremy K. Hourigan,‡ Oscar Lovera§ and Brian W. Romans¶ *Geological Sciences, Indiana University, Bloomington, IN, USA †Geological & Environmental Sciences, Stanford University, Stanford, CA, USA ‡Earth Sciences, University of California, Santa Cruz, CA, USA §Earth & Space Sciences, University of California, Los Angeles, CA, USA ¶Geosciences, Virginia Polytechnic Institute and State University, Blacksburg, VA, USA ABSTRACT The Patagonian Magallanes retroarc foreland basin affords an excellent case study of sediment burial recycling within a thrust belt setting. We report combined detrital zircon U–Pb geochronology and (U–Th)/He thermochronology data and thermal modelling results that confirm delivery of both rap- idly cooled, first-cycle volcanogenic sediments from the Patagonian magmatic arc and recycled sedi- ment from deeply buried and exhumed Cretaceous foredeep strata to the Cenozoic depocentre of the Patagonian Magallanes basin. We have quantified the magnitude of Eocene heating with thermal models that simultaneously forward model detrital zircon (U–Th)/He dates for best-fit thermal his- tories. Our results indicate that 54–45 Ma burial of the Maastrichtian Dorotea Formation produced 164–180 °C conditions and heating to within the zircon He partial retention zone. Such deep burial is unusual for Andean foreland basins and may have resulted from combined effects of high basal heat flow and high sediment accumulation within a rapidly subsiding foredeep that was floored by basement weakened by previous Late Jurassic rifting. -
Structure of the Southern Cordillera Oriental (Argentinean Andes)
6th International Symposium on Andean Geodynamics (ISAG 2005, Barcelona), Extended Abstracts: 154-157 Structure of the southern Cordillera Oriental (Argentinean Andes) Nuria Carrera \ Josep Anton Mufioz \ Francesc Sàbat ', Ricardo Mon 2, ft Eduard Roca 1 1 Dpt. de Geodinàmica i Geofisica, Facultat de Geologia UB, Marti i Franqués sin, 08028-Barcelona; [email protected], [email protected], sabat@edu, [email protected] 2 Dpt. de Geologia, Facultat de Ciencias Naturales e Instituto Miguel Lillo, Universidad Nacional de Tucurnàn, Miguel Lillo 2054000 Tucurnàn (Argentina) Introduction This communication is aimed to describe and discuss the generaJ structure and the tectonic evolution of the southern edge of the Cordillera Oriental, next to the Puna. The structure of the study area consists of a system of N-S trending Andean thrust and fold structures, which are superimposed on a Cretaceous rift system (Salta rift). Inversion of the Salta Basin has been documented from surface data in the Cordillera Oriental (Grier at al., 1991) as weil as from seismic data east of the studied area in the Santa Barbara system (Cristallini et al., 1997). In most of the stu died area there are not sei sm ic data. This work has taken advantage of the excellent outcrops presents in the area, thus this is a field based work. Satellite image interpretation has also been incorporated. Detailed mapping of new areas as weil as re-interpretation of previously described areas brings new insights into the tectonic evolution of the southern Cordillera Oriental. Stratigraphy The southern edge of the Cordillera Oriental is characterized by the presence of extensive outcrops of Precambrian basement rocks, the absence of Paleozoic seri es and the irreguJar distribution of very thick Mesozoic and Tertiary continental clastic sequences (3-12km) (Figure 1). -

Basement inheritance and Foreland basin progressive shallowing of an east-dipping subducting slab are important mechanisms of foreland partitioning, as Provenance dictated by the preexisting (pre-Andean) structural architecture and forelandward (eastward) advance of Late U-Pb geochronology Cretaceous arc magmatism. Previously recognized growth strata help define the timing of fold-thrust belt Hf isotopes shortening and retroarc basement-involved uplift, but the precise consequences for sediment routing remain poorly understood, with uncertainties in patterns of basin evolution before, during, and after shallowing and resteepening of the subducting slab. -
