Although Yemen is a single country today, it once consisted of three separate political entities. The territory’s first geological survey took place aboard the HMS Palinurus in 1862, when Henry Carter of the Geological Survey of India made a series of observations of the coastline; but the region was rarely visited and was considered as a poor oil prospect in the first decades of the twentieth century.

It’s good to be reminded of this one simple industry fact: “As a rule, geologists love to get out in the field to see classic and interesting outcrops that provide a better understanding of depositional facies, hydrocarbon reservoir systems, and anything related to geology.” That’s AAPG member Mark Longman, this year’s field trip chair for the upcoming AAPG Annual Convention and Exhibition, set May 31-June 3 in Denver.

The Upper Jurassic Smackover formation in northern Louisiana and surrounding states has been explored and drilled for decades, but has only recently seen the sophisticated approach needed to decipher its challenging geology.

It wasn’t easy, that’s for sure. But AAPG member Tom Marshall – a geologist who moved to Alaska in his early 30s, enamored by the idea of homesteading in the Matanuska-Susitna Valley – managed to change the future of the entire state with a suggestion that sounded as promising as a dry hole.

Like numerous other geologic formations, the allure of the Wilcox has waxed and waned owing to fluctuating commodity prices, among other issues. As hydrocarbon prices recovered and technology applications like hydraulic fracturing became commonplace, the Wilcox beckoned anew, attracting principally the mom-and-pop shops and the small to mid-size independents.

As we transition to a new commercial reality for our industries, there has never been a more important time for Earth Scientists to take a seat at the table. This workshop is designed to share our knowledge of the petroleum sector with other branches of the geosciences, while learning from their experiences. Join us for this hybrid online and in-person workshop on 6 July 2022.

Trip leader(s): Josep Anton Muñoz, Pablo Granado and Eduard Roca Limit: 20 Participants 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. -->

VG Abstract

In comparison with the known boundary conditions that promote salt deformation and flow in sedimentary basins, the processes involved with the mobilization of clay-rich detrital sediments are far less well established. This talk will use seismic examples in different tectonic settings to document the variety of shale geometries that can be formed under brittle and ductile deformations.

VG Abstract

The Betic hinterland, in the westernmost Mediterranean, constitutes a unique example of a stack of metamorphic units. Using a three-dimensional model for the crustal structure of the Betics-Rif area this talk will address the role of crustal flow simultaneously to upper-crustal low-angle faulting in the origin and evolution of the topography.
