The elusive Rivera-Cocos plate boundary: not diffuse

Román Alvarez; Vsevolod Yutsis

Abstract Inland and offshore gravimetric determinations in the Southern Colima rift in western Mexico allowed for the construction of a Bouguer anomaly map of the area. Four submarine canyons of tectonic relevance are located in the offshore area. Gravimetric models of the oceanic subducting slab were calculated from the residual Bouguer anomaly along six trench-parallel lines and three trench-perpendicular lines including the area of the canyons. The former lines show considerable distortion of the slab that we attribute to compression, while the latter show distinct dipping angles of the oceanic slab at distances of around 75 km from the trench: the westernmost line shows a dip angle of 55° between depths of 20 and 70 km, while the easternmost shows a dip angle of 32° at depths between 18 and 50 km. We submit that the former represents a section of the subducting Rivera plate, and the latter represents a section of the Cocos plate. Extracting coordinates of representative points on the surface of the nine slab models allowed for a reconstruction of the slab surface: the transition from the Rivera to the Cocos plate is marked by topographic gradients in the modelled slab surface suggesting the trajectory of the boundary between the plates. We propose a tectonic model that includes a transpression zone involving the marine platform and the Southern Colima rift and a transtension zone in the Northern Colima rift: the Colima Volcanic Complex is located in the transition zone between them.

Bottom topography, recent sedimentation and water volume of the Cerro Prieto Dam, NE Mexico

The Cerro Prieto dam, a relatively small water reservoir in NE Mexico, is one of the main resources of potable water for Monterrey, a city with a population of about four million inhabitants. A high resolution seismic study using non-linear parametric sub-bottom echo-sounder SES-2000 was carried out in this water reservoir. High resolution acoustic data interpretation shows that the thickness of recent sediments due to siltation of the reservoir reaches 3.5-4.0 m. It shows a high recent sedimentation rate (1-2 up to 14 cm/ year). Based on the echo-sounder data, the first bathymetric map and a digital model of recent sediment thickness were designed. A significant (5-12%) difference between the volume capacity value used by National Commission of Water (CNA) and acoustic survey results was revealed. Differences between the CNA and acoustic data indicate storage losses from 12-17 up to 30 million cubic meters. The results obtained through study such as this one, could be useful to improve a water resources management.

A volcanic centre in Mexico's Pacific continental shelf

Román Alvarez; Fernando Corbo Camargo; Vsevolod Yutsis; Jorge Arzate

Abstract On the continental platform of western Mexico, there is a young island of volcanic origin: Isla Isabel. It is the only volcanic manifestation in the region, contrasting with Islas Tres Marías, which are not volcanic. We aim at characterizing the source of the volcanic activity present in this particular location. Under Isla Isabel there is a bathymetric bulge that rises 60–80 m above the platform, and extends 20 km in the NW–SE direction and 17 km in the perpendicular direction. Isla Isabel is the only emerged portion of the bulge, extending only 1.8 km in the NW–SE direction. The island shows Plio-Pleistocene volcanic activity, including the formation of maars and the presence of mantle xenoliths. Using independent 2D modelling and 3D inversion methods for the gravity and magnetic fields, we analyse the nature of the bulge and its surroundings. A magnetotelluric station yields information about the electrical resistivity under the island, with penetration depths of approximately 20 km. The models are consistent with the presence of dense bodies of varying magnetizations that are interpreted as intrusive bodies. Results support the presence of an intrusion that locally has raised the ocean-floor topography. Volcanic activity projected from the bulge created Isla Isabel; the existence of additional, submerged volcanic centres in the area is most probable. We are inclined to identify the Isabel Bulge as a laccolith.

Geophysical modelling of Isla Isabel: a volcanic island on the Mexican continental margin

Román Alvarez; Fernando Corbo Camargo; Vsevolod Yutsis

Abstract Isla Isabel is a small island located on top of a 20 km-long bathymetric bulge, part of the continental shelf of Nayarit in the vicinity of the mouth of the Gulf of California; it is of volcanic origin with tuff cones, basaltic flows and Surtseyan-type explosion craters exposed. Geophysical surveys were carried out in order to model the geological bodies associated with the local gravity and magnetic fields. 2D and 3D models are presented, and a 1D inversion model is derived from magnetotelluric data. Analysis of the density models of the upper 1400 m suggests two growth stages for Isla Isabel in this depth range: the first one reaching 800 m in depth and the second one projecting from that depth to the surface. The corresponding magnetic susceptibility models concur with this observation. The bodies projected to the surface appear to correspond to diatremes. The 1D magnetotelluric inversion shows two conductive anomalies within the crust between 3–5 and 8–17 km, followed by a resistive substratum that coincides with the seismically derived limit of the Earths crust at the islands position.

Structural evidence of enhanced active subsidence at the bottom of a maar: Rincón de Parangueo, México

Abstract Rincón de Parangueo is a Quaternary maar that has been recently desiccated. The crater was partially occupied by a soda lake, and near the shoreline microbialites have formed. Evaporites (mainly trona and halite) precipitated as the water level dropped. Active subsidence of the lake floor (c. 24 m since 1980) produced countless structures close to the lakeshore, where deformation is extensional. Closer to the depocentre, in the western half of the basin, gliding/spreading produced folds and mud-injection domes. The most remarkable structure throughout the basin is a monocline that forms a ring-like, nearly continuous scarp, approximately 15 m high, which in the eastern half of the basin was produced as a fault-propagation fold developed above the buried diatreme–country rock boundary. A more diffuse (wider) monocline, locally associated with compressive structures, occurs in the western half of the basin. These structures are interpreted as having developed above a gently inclined, irregular lake sediment–country rock (andesite) interphase. The monocline was modified by high-angle extensional faults/fractures with large heaves/apertures. In the eastern half of the basin, there is a second (outer) scarp, approximately 13 m high, formed by a high-angle, listric, normal fault. Rollover antiforms occur in the hanging wall of this structure. Rincón is an example of centripetal gravitational gliding/spreading.

Application of Spectral Decomposition Methods to the Definition of Stratigraphic Features Associated with Channel Reservoirs in the Southeast Petroleum Province, México

Fernando Alvarez San Román; Vsevolod Yutsis

Spectral decomposition transforms seismic data into the frequency domain via mathematical methods such as the discrete Fourier transform, S-transform, time–frequency continuous wavelet transform and continuous wavelet transform. The transformed results include tuning cubes and a variety of discrete common frequency cubes, which reveal structural and stratigraphic features, such as channels, thin bed reflections, and subtle faults. When a spectral decomposition algorithm is applied to seismic reflection data, it breaks down the seismic signal into its frequency components and this allows visualization of the data at specific frequencies, and identification of stratigraphic and structural features that would otherwise be overlooked in full bandwidth displays. The stratigraphic features delineated through the different algorithms, such as channels and their sedimentary facies, could be related to the presence of reservoir rock, i.e., underground rock units where the oil migrates and accumulates. An example from the Southeast Petroleum Province in México is presented.
