“…Comparable interpretations are given for similar deposits of the Higueruelas Fm in other areas of the Iberian Basin (Zaragoza province) by Ipas et al (2004). Similar deposits have been also described in the Bovalar Fm (middle Tithonian-early Berriasian) at the Penyagolosa sub-basin (Maestrat Basin), which have been interpreted as highly-agitated shoals developed in the inner ramp of a carbonate platform (Bádenas et 1975;James, 1977;Enos, 1983, Caron et al, 2005Diedrich et al, 2011;Sano et al, 2012). These sequences were occasionally subaerial exposed, as suggested by the presence of irregular and brecciated tops and the thinning-downwards vertical structures, typically caused by edaphic processes (e.g.…”

The study of the Upper Jurassic-Lower Cretaceous deposits (Higueruelas, Villar del Arzobispo and Aldea de Cortés Formations) of the South Iberian Basin (NW Valencia, Spain) reveals new stratigraphic and sedimentological data, which have significant implications on the stratigraphic framework, depositional environments and age of these units. Moreover, these new data encourage revising the previously proposed stratigraphic correlations between the studied units and those deposited in adjacent areas of the Iberian Basin.The Higueruelas Fm was deposited in a mid-inner carbonate platform where oncolitic bars migrated by the action of storms and where oncoid production progressively decreased towards the uppermost part of the unit. The overlying Villar del Arzobispo Fm has been traditionally interpreted as an inner platform-lagoon evolving into a tidal-flat. Here it is interpreted as an inner-carbonate platform affected by storms, where oolitic shoals protected a lagoon, which had siliciclastic inputs from the continent. The Aldea de Cortés Fm has been previously interpreted as a lagoon surrounded by tidal-flats and fluvial-deltaic plains. Here it is reinterpreted as a coastal wetland where siliciclastic muddy deposits interacted with shallow fresh to marine water bodies, aeolian dunes and continental siliciclastic inputs.The contact between the Higueruelas and Villar del Arzobispo Fms, classically defined as gradual, is interpreted here as gradual and rapid, because the transition between both units comprises few meters. More importantly, the contact between the Villar del Arzobispo and Aldea de Cortés Fms, previously considered as unconformable, is here interpreted as gradual.The presence of Alveosepta in the Villar del Arzobispo Fm suggests that at least part of this unit is Kimmeridgian, unlike the previously assigned Late Tithonian-Middle Berriasian age. Consequently, the underlying Higueruelas Fm, previously considered Tithonian, should not be younger than Kimmeridgian. Accordingly, sedimentation of the Aldea de Cortés Fm, previously considered Valanginian-Hauterivian, probably started during the Tithonian and it may be considered part of the regressive trend of the Late Jurassic-Early Cretaceous cycle. This is consistent with the dinosaur faunas, typically Jurassic, described in the Villar del Arzobispo and Aldea de Cortés Fms Keywords: Mixed carbonate-siliciclastic platform, coastal wetland, Foraminifera, Spain, Kimmeridgian, Tithonian Resumen El estudio de los depósitos del Jurásico Superior-Cretácico Inferior (formaciones Higueruelas, Villar del Arzobispo y Aldea de Cortés) de la Cuenca Suribérica (NO provincia de Valencia, E España) ha revelado nuevos datos estratigráficos y sedimentológicos, que tienen implicaciones importantes sobre el marco estratigráfico, el ambiente sedimentario y la edad de estas unidades. Además, estos nuevos datos sugieren que se deberían revisar las correlaciones estratigráficas realizadas previamente entre las unidades estudiadas y aquéllas depositadas en otras áreas adya...

“…Landsat TM images have been used with mixed success to map igneous and metamorphic units (e.g., [11,[13][14][15][16][17]), as well as clastic, carbonate, and evaporitic lithologies (e.g., [18][19][20][21][22]). TM data have been applied with some success in the mapping of prominent zones of mineral alteration such as those marked by the presence of abundant oxides and hydroxides (e.g., [23,24]).…”

Abstract:In order to better constrain the utility of multispectral datasets in the characterization of surface materials, Landsat Thematic Mapper (TM) data were evaluated in the discrimination of geological classes in the Cape Smith Belt of Quebec, a greenstone belt that hosts Early Proterozoic units including those of the Purtuniq ophiolite. Ground-based measurements collected for the study area highlight the importance of chemical alteration in controlling the reflectance properties of key geological classes. The spatial distribution of exposed lithologies in the study area was determined through (1) image classification using a feedforward backpropagation neural network classifier; and (2) generation of fraction images for spectral end members using a linear unmixing algorithm and ground reflectance data. Despite some shortcomings, the database of surface cover generated by the neural network classifier is a useful representation of the spatial distribution of exposed geological materials in the study area, with an overall agreement with ground truth of 87.7%. In contrast, the fraction images generated through unmixing are poor representations of ground truth for several key lithological classes. These results underscore both the considerable utility and marked limitations of Landsat TM data in the mapping of igneous and metamorphic lithologies.

“…Wind and open ocean current speed and direction, and initial surface geometries based on modern bathymetry were specified for two platforms of contrasting size; south Cocos (Keeling) platform in the Indian Ocean and the rather larger Caicos platform in the Caribbean. Figure 3.10 shows good agreement between synthetic facies maps and those based on sediment sampling and analysis of Landsat imagery by Kaczmarek et al (2010) which postdates the modelling work. Current speeds on the simulated south Cocos platform also show a good match with those measured for passages between the barrier islands and across the platform.…”

Synthetic facies (f and i) are compared with direct observation of facies distribution based on sample characterization (a, after map of Smithers, 1994) and that inferred by an analysis of Landsat imagery (by Kaczmarek et al (2010) (c and h). For Coco--Keeling we also show predicted current velocity (d), and resulting redistribution of coarse and fine sediments (e).…”
