Trip leader(s): Josep Anton Muñoz, Pablo Granado and Eduard Roca Limited spaces available The aim of this 2-day field trip is the recognition of the key structural features of a fold and thrust belt detached on salt that has resulted from the inversion of a previous passive margin. To achieve this objective, some of the key and most spectacular localities of the southern Pyrenees have been selected along the ECORS-Pyrenees transect. This is a reference cross-section provided that for many years a huge amount of geological and geophysical data sets has been collected and integrating into a kinematic model of the South-Pyrenean fold and thrust belt. Subsurface data (well logs and seismic sections) will be combined with field observations. One of the main characteristics of the southern Pyrenees is the preservation of the synorogenic sediments since the earlier stages of deformation, which not only provide time constraints but also allow us discussion of kinematics of fault-related folds and thrust systems. Finally, the mild contractional deformation permits deciphering the initial geometry of the rift system and the salt structures that configure the structural grain of the passive margin before the inversion, allowing discussion of the role that these structures play during the fold and thrust belt development. Itinerary: (day by day details of the trip) Day 1 Stop 1.1: The South-Pyrenean thrust front. Sant Llorenç de Montgai Structure of a frontal thrust system and related unconformities. Out of sequence thrusts and synorogenic sediments. The frontal thrust system of the South-central Pyrenees has been detached into the Triassic evaporites and involves a thin Mesozoic succession. It is characterized by an emergent thrust system during the sedimentation of upper Eocene and lower Oligocene continental sediments. Frontal thrusts were progressively buried by conglomerates, triggering a break-back thrusting sequence and the development of out-of-sequence thrusts bringing together strongly different Mesozoic successions, such as the Montroig thrust in the picture. Stop 1.2: The Ager basin and the Montsec thrust sheet. Fontllonga The Ager basin in the footwall of the Montsec thrust. The Montsec thrust sheet developed from the Paleocene to the Early Eocene as recorded by continental to shallow marine sediments deposited in its footwall (Ager basin) as well as in the Tremp-Graus piggy-back basin. The lower Eocene sediments of these basins grade westward into the slope succession filling the Ainsa basin at the footwall of the Montsec thrust. Stop 1.3: The frontal structure of the Montsec thrust sheet. Ametlla (optional: Montrebei) Fault-propagation fold related with the inversion of Early Cretaceous extensional faults and growth deltaic sediments in the footwall syncline. The Montsec thrust sheet involves the northern part of the Upper Cretaceous foreland basin characterised by a strong subsident turbiditic trough at the footwall of the Bóixols thrust. These turbidites grade southward into a carbonatic platform that constitutes the backbone of the Montsec Range (main ridge and cliff of the pictures). Underneath the Upper Cretaceous carbonates, some Early Cretaceous extensional faults are preserved in the hanging wall of the Montsec thrust, but others have controlled the development of a hanging wall frontal anticline. The geometry of this anticline as well as the structure of the growth sediments in the footwall Ager syncline are visible in the field. The subthrust geometry will be discussed integrating surface observations and the available seismic and well data. Overnight in Tremp Day 2 Stop 2.1: The Sant Corneli-Bóixols anticline Inversion of the rift margin The Sant Corneli-Bóixols anticline is the most prominent frontal structure of the Bóixols thrust sheet in the central Pyrenees. This fold trends east–west and crops out for greater than 40 km along strike. The Sant Corneli-Bóixols anticline involves a thick Mesozoic succession detached on top of Triassic evaporites. The prefolding sequence consists of up to 5 km of prerift, synrift, and postrift carbonates ranging in age from Jurassic to Upper Cretaceous. Synfolding Upper Cretaceous sediments start with the upper Santonian carbonates and continue with a succession of Campanian and Maastrichtian marls and turbidites. The Sant Corneli–Bóixols anticline is an example of an inversion fold developed along the rift margin of the Lower Cretaceous basin. Its geometry is related with the inverted extensional system. In particular, the three-dimensional geometry, including the saddles between culminations, is inherited from the previous transfer faults of the segmented rift margin. Available seismic data and 3 exploratory wells constrain the geometry at depth. Stop 2.2: The synororgenic Paleogene conglomerates Inverted Lower Cretaceous basin and Eocene-Oligocene synorogenic conglomerates at Collegats gorge. Stop 2.3 (optional): The Sopeira and Aulet minibasins. Sopeira Minibasins developed by extensional collapse and salt evacuation during the thermal subsidence at the southern Pyrenean rift margin. Inversion of these mini-basins at the early stages of Pyrenean contractional deformation during Late Cretaceous. Additional logistic information Transportation Transportation will be with a small bus, assisted by minivans to have access to some of the outcrops. Physical demand, equipment and safety This is an easy field trip with very easy and limited hikes to get to the outcrops. Outcrops will be from main sealed roads. Safety vests will be available, to be used by everybody of the group wherever required and asked to. There will be First Aid Kits available in each car during fieldwork. Climate The climate during mid-end November in the fieldwork area can be cold and rainy, although dry and sunny days may occur as well. The temperature for November in Tremp can range between 30C and 170C. Participants should be prepared in case we should encounter bad weather and you should bring warm and waterproof clothes and suitable hiking boots.

Join us in Salzburg, the “castle of salt” and cradle of Mozart and Doppler, for a meeting aimed at bringing together different perspectives in the science of evaporite basins: from their formation to their deformation, from description and characterization to modelling. Exploratory success in evaporite-rich basins worldwide has depended on the role of evaporites as a deformable substrate, as a seal, or even as a good thermal conductor. The aim of this workshop is to improve our understanding and predictive ability by addressing evaporite systems in an integrated manner, all the way from precipitation to structuration, and exploring the multiple properties of evaporite sequences. The pre- and post-meeting field trips will also explore the salt mining heritage of the region, first exploited by the Celts 3500 years ago, and the salt-related structures of the Northern Calcareous Alps.

VG Abstract

Microseismicity induced by hydraulic fracture stimulation of a horizontal well was mapped with a near-surface buried array. Distinct linear trends of events were not parallel to the direction of fast shear wave polarization measured in the reservoir with a crossed-dipole anisotropy tool. Analysis of core from a nearby well revealed numerous calcite-filled fractures that did not induce shear wave polarization, but did significantly impact the failure behavior of the reservoir rock during the stimulation treatment. Hydraulic fracture simulation with DFN modeling and source mechanism analysis supports the interpretation of reactivated existing fractures rather than the formation of hydraulically-induced tensile fractures.

VG Abstract

Analysis of microseismicity induced by hydraulic fracture stimulation in the Marcellus Shale shows changes in stress state for different zones of failure. During the treatment, shear failure occurs on both the J1 and J2 fracture orientations in response to different maximum stress orientations, indicating localized changes in the orientation during the treatment. Reactivation of a fault near the wellbore is associated with failure mechanisms with a higher volumetric component, indicating possible inflation of faults and fractures by the introduction of the slurry. Quantification of the stress conditions that are associated with inflation could potentially be used to optimize the stimulation by identifying which fractures will preferentially take on slurry volume.

VG Abstract

The carbonate sequences that were deposited in the now exhumed Tethyan Ocean influence many aspects of our lives today, either by supplying the energy that warms our homes and the fuel that powers our cars or providing the stunning landscapes for both winter and summer vacations. They also represent some of the most intensely studied rock formations in the world and have provided geoscientists with a fascinating insight into the turbulent nature of 250 Million years of Earth’s history. By combining studies from the full range of geoscience disciplines this presentation will trace the development of these carbonate sequences from their initial formation on the margins of large ancient continental masses to their present day locations in and around the Greater Mediterranean and Near East region. The first order control on growth patterns and carbonate platform development by the regional plate-tectonic setting, underlying basin architecture and fluctuations in sea level will be illustrated. The organisms that contribute to sequence development will be revealed to be treasure troves of forensic information. Finally, these rock sequences will be shown to contain all the ingredients necessary to form and retain hydrocarbons and the manner in which major post-depositional tectonic events led to the formation of some of the largest hydrocarbon accumulations in the world will be demonstrated.
