“…The Miocene-Pliocene unconformity was first described in the 1930s along the margins of the asymmetric basins of the Rio Grande rift, and it has since been recognized across most of Española Basin ( Fig. 2; Bryan, 1938;Bryan and McCann, 1938;Wright, 1946;Stearns, 1953Stearns, , 1979Seager et al, 1984;Connell et al, 2013;Koning et al, 2013Koning et al, , 2016aChamberlin et al, 2016), and more recently, outside of the rift zone (for example, Ocate volcanic field east of the rift; O 'Neill, 1998;Nereson et al, 2013). In the rift, the unconformity has been documented from the Arkansas Basin in Colorado to the Rincon Basin in southern New Mexico.…”

“…Extension initiated later in the northern rift (30-26 Ma, possibly 33-26 Ma) than the southern rift . Angular unconformities related to the onset of extension in the San Luis and Española Basins are bracketed at 28-27 Ma and 30-26 Ma, respectively (Lipman and Mehnert, 1975;Koning et al, 2013). In these basins, ca.…”

“…The unconformity is particularly extensive in the Española Basin, where it covers >90% of the basin's area, if one interpolates between areas of preservation (Galusha and Blick, 1971;Spiegel and Baldwin, 1963;Manley, 1979;Baldridge et al, 1994;Koning et al, 2013), and it is absent only in restricted depocenters immediately adjacent to the Pajarito fault system (Fig. 2).…”

“…Outcrop and well data in the Española Basin generally show a sharp lithologic change across the contact corresponding with the unconformity. In the north-central portion of the basin, the unconformity is overlain by basalts that have been dated at 4.9-3.3 Ma (Koning et al, 2011(Koning et al, , 2013Maldonado et al, 2013;Repasch et al, 2017). Underlying strata range from 10 Ma to 6 Ma ( Repasch et al, 2017).…”

We use tectonic subsidence patterns from wells and stratigraphic sections to describe the mid-Miocene to present tectonic subsidence history of the Rio Grande rift. Tectonic subsidence and therefore rift opening were quite fast until ca. 8 Ma, with net subsidence rates (~25-65 mm/k.y.) comparable to those of the prerupture phase of rifted continental margins. The rapid subsidence was followed by a late Miocene-early Pliocene unconformity that developed mainly along the flanks of most rift basins. The age of its associated lacuna is spatially variable but falls within 8-3 Ma (mostly 7-5 Ma) and thus is synchronous with eastward tilting of the western Great Plains (ca. 6-4 Ma). Tectonic subsidence rates either remained similar or decreased after the Miocene-Pliocene unconformity. North of 35°N, our analysis of geoid-to-elevation ratios suggests that, at present, topography of the Rio Grande rift region is compensated by a component of mantle-driven dynamic uplift. Previous work has indicated that this dynamic uplift is caused by focused vertical flow in the upper mantle resulting from slab descent and fragmentation of the Farallon slab, and Rio Grande rift opening, which affected the Rio Grande rift area beginning in the late Miocene. The spatial distribution and timing of the unconformity, as well as eastward tilting of the western Great Plains, can be explained by this dynamic mantle uplift, with contributions from variations in rift opening tectonics and climate. The focused mantle upwelling is not associated with increased rift opening rates.

This paper analyzes throw-depth (T-z) profiles from a high resolution 2D reflection seismic grid in the central basin of Lake Malawi to investigate whether evidence exists: 1) for migration of faulting away from the border fault of the half-graben; and 2) that faults in the hangingwall lengthened over the last 1.3 million years. We use the high-precision age model from a 2005 scientific drilling project in our study area to constrain the ages of our seismic horizons and examine a fault array and two individual faults within the hangingwall of the central basin border fault. We account for climatic and sedimentological controls on stratal growth with a lake-level curve that accompanies the age model. A comparison of our hangingwall T-z profiles with published throw-distance (T-x) profiles for the border fault shows synchronous faulting over the last 1.3 m.y. rather than basinward migration of faulting. Furthermore, we find no evidence for significant propagation of the tips of the hangingwall faults in the last 1.3 m.y. and conclude that the lack of basinward migration of faulting is a consequence of strain localization on faults established at an early stage in basin development.
