“…10). Near Camisea, the Manu arch records thinning of the Paleozoic and Mesozoic section atop it (House et al, 1999), which would have had the effect of maintaining Paleozoic source intervals at shallow levels over a long time period. In other words, the basement arch helped counteract the tendency of Paleozoic sources to prematurely yield hydrocarbons (compared with the late Cenozoic age of trap formation) in response to burial by (1) late Paleozoic retroarc basin fi ll, (2) Mesozoic rift fi ll, and (3) early to mid-Cenozoic foreland basin fi ll, thereby preserving and protecting the petroleum system so that young traps could be charged in late Cenozoic time.…”

“…The ~1000-km-long segment of the fold belt in southeast Peru and northwest Bolivia differs from areas to the north and south in that there is little evidence of the pronounced Mesozoic rifting that occurred near the mountain front in Colombia, northern and central Peru, and Argentina. Triassic-aged rift-fi ll units are present in thrust sheets in the Eastern Cordillera in northwest Bolivia and southern Peru, but in the Subandes, the Lower Cretaceous strata typically sit on Permian strata (House et al, 1999), indicating that this area was on a structural high (i.e., Manu and Madidi arches) or perhaps a regional rift shoulder while areas to the west were extending in Permian and Mesozoic time (Figs. 2, 3, and 6).…”

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, orogenparallel ("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 subbasins 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 distribution of multiple petroleum system elements in post-Ordovician time. Second, the mid-Carboniferous "Chañic" event was a less profound event that created modest 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. Third, protracted rifting that lasted throughout the Mesozoic provided the framework for deposition of many of the source rocks in the Subandean belt, but most are not as widely distributed as the Paleozoic sources in Bolivia and Peru. We attribute variations in the style of Andean deformation and distribution of oil versus gas in the Subandes largely to differences in pre-Cenozoic structure along

“…To the southwest, its transition with the Madre de Dios Basin is made by the Fitzcarrald and Manu arches. The Manu Arch corresponds to a structure located in the northwest part of the Madre de Dios Basin, with a general NW‐SE trend, being characterized by an uplift that exposed crystalline basement rocks along their axes during the late Permian to late Cretaceous (House et al, 2000). The positioning of these arches agrees with Stewart et al (2018) and despite having different ages, they represent important highs in the basement of the transition region between the two basins.…”

“…Later, the ANP started to use this name in its bidding rounds for the exploration and production of oil and natural gas. However, the separation between the Peruvian and Bolivian basin and the southern portion of the basin located within the Brazilian territory seems to be very well established by the Manu Arch (Figure 16a), which corresponds to a basement uplift developed during the Late Permian (House et al, 2000). Also, an eventual expansion of the Madre de Dios Basin area towards the Brazilian territory generates operational and criterium confusion since the Acre Basin portion located north of Fitzcarrald Arch did not receive the sub‐Andean Marañon and Ucayali nomenclature in previous studies while both, the Contaya Arch that establishes the northern boundary and the Manu Arch, coincide with the approximate position of the geogra0phical boundaries between countries.…”

The Acre Basin basement (NW Brazil) and the transition from the intracratonic to retroarc foreland basin system

The understanding of the crustal transition between orogenic zones and cratonic portions in distal regions of foreland basins has received increasing attention, but the analysis is often hampered by the sedimentary cover. Despite the peculiar location of the Acre Basin, specifically between the Amazonian Craton and the sub-Andean zone, local basement studies are still scarce due to lacking seismic data and exploratory wells. Therefore, this work aims to map basement depths, estimate crustal compositions and identify the main depocenters, structures and limits of Acre Basin using an integrated analysis to understand better the region lithospheric evolution, its relationship with the Amazonian Craton and its positioning within the Andean orogeny. For that, we used well, 2D seismic reflection, airborne and ground gravity and magnetic data as well as the EMG2008. Tilt Depth estimates indicate basement depths between 500 and 7800 m and larger sedimentary thicknesses in the northern portion. Additionally, we modelled groups of potential sources between 0.1 and 22 km and Moho depths between 26 and 37 km.Compositionally, the upper crust consists dominantly of meta-sedimentary and low-grade metamorphic rocks and granites, indicating that the sub-Andean and Acre Basins share a similar basement. Thus, there are indications that the basement of the Acre Basin is essentially formed by the Sunsás province in the Amazonian Craton. However, local differences in basement depth, magnetic susceptibility and exploratory potential led to the subdivision into Divisor and Xapuri sub-basins, north and south of the Fitzcarrald Arch, respectively. Finally, it was possible to establish the limits of the Andean orogeny influence in the Acre Basin and delimit the area of the Western Amazon Foredeep installed during the Neogene.
