Field Trip Leader: Frank Mattern, Sultan Qaboos University (SQU)
Date: 12th December
Time: 8am – 5pm
Registration for the field trip is now closed
The field trip will lead to the Sunub/Ansab area to discuss the postobductional extensional, NW-striking Frontal Range Fault which formed in the course of gravitational collapse of the Saih Hatat and Jabal Akhdar domes. The fault is marked by the occurrence of listwaenite. The vertical displacement amounts to a few to several kilometers. Shearing ensued in two intervals, during the late Cretaceous to early Eocene and probably Oligocene. At this fault segment, the first stage is characterized by extension. The second stage is marked by dextral motion, including local transtension. The listwaenite dispalys the unusual feature of a ductile shear zone which trends obliquely to the Frontal Range Fault.
At the hot spring of Hammam Al Ali the Frontal Range Fault is superbly exposed. The presence of the hot spring may well be related to the fault’s transtensional releasing bend as well as the occurrence of a nearby basalt which intruded the Paleocene-Eocene Jafnayn Formation.
Gravitational collapse also created contractional structures due to E-W compression. Near Jafnayn, a wide open syncline in Eocene formations will be shown whose axis trends N-S, and on the SQU campus a syndepositional, E-dipping Miocene thrust formed within the Barzamen Formation. It displays ramps and an intervening flat. In Al-Khod Village, pillow basalt was pressed over a mudflow deposit along a west-dipping reverse fault. The two compressive faults could have formed coeval conjugate faults. Compression is related to convergence of downthrown hanging wall blocks.

Stop 1: Qartaba village: Overview of the stratigraphy and depositional environment of the Levant margin by looking at a panoramic view of the stratigraphic succession.
Stop 2: Laqlouq: quick stop to visualize the folding of the Qartaba anticline
Stop 3: Tannourine: Overview of the large E-W strike-slip faults and discussion on their geodynamic history and implications on the petroleum system
Stop 4: Tannourine-Douma road: Overview of the Cretaceous carbonate monocline and discussion on facies variation
Stop 5: Chekka quarry: Examine the Campanian thermogenic source rocks and the Paleocene depositional systems.

One of the last remaining hydrocarbon exploration frontiers of the Gulf of México (GoM) “Super-Basin” is the Early Mesozoic and Paleozoic sedimentary section stratigraphically below the autochthonous Middle Jurassic Louann Salt and its equivalents.
Join AAPG for presentations from both Industry and Academia on themes including the Potential of the Paleozoic of the circum-GoM Region.
Date: Friday 28 – Saturday 29 February 2020 (2 days)
Instructor: Ken McClay, Professor of Structural Geology
This 2 day short course will focus firstly on the development of extensional basins, rifts and passive margins followed by inversion of these systems and the formation of thick and thin-skinned thrust belts. Extensional fault geometries, segmentation and linkages will be analysed as well as the architectures of extensional basins illustrated with field examples from the Gulf of Suez and Northern Red Sea as well as seismic examples from rift basins and passive margins. Inversion systems will be discussed in the context of how basement rift fault systems influence and control inversion geometries. Thick and thin-skinned orogenic systems will be examined in the context of inverted basins and thin-skinned thrust systems using examples from PNG, the Pyrenees, the Zagros fold and thrust belt and other systems. Characteristic structural styles and hydrocarbon systems in these terranes will be will be copiously illustrated using field, seismic, physical sand box and numerical models.
Who should attend:
Final year Geoscience students; starting geoscientists in the petroleum industry as well as mid- senior level geoscientists needing modern concepts of structural geology for the petroleum industry.
Ken McClay, Professor of Structural Geology, - BSc Honours degree in Economic Geology from Adelaide University, - MSc in Structural Geology & Rock Mechanics and PhD in Structural Geology from Imperial College, University of London, and DSc from Adelaide University: Emeritus Professor in the Department of Earth Sciences, Royal Holloway University of London and an Adjunct Professor in the Australian School of Petroleum at Adelaide University.
From 1991 until December 2018 he was Professor of Structural Geology and Director of the Fault Dynamics Research Group at Royal Holloway University of London. He carried out wide-ranging research on all aspects of applied structural geology. This has involved field research in NW Scotland, the Spanish Pyrenees, Indonesia, Yemen, Iran, Australia, Canada, USA, Chile, Argentina, Greenland, Norway, Turkey, Ethiopia and Gulf of Suez and Red Sea Egypt. His research interests include extensional, strike-slip, thrust and inversion terranes. He ran a large experimental analogue modelling laboratory for the simulation of fault structures and sedimentary architectures at Royal Holloway. He has written a book for mapping structures in the field, edited five major volumes on thrust tectonics, and has published widely on structural geology and tectonics and he is a consultant for the international petroleum industry and has given many short courses for the industry.
Ken focuses on field analogues for geological structures to illustrate structural styles and mechanical stratigraphy, on analogue modelling of faults and fold systems and on seismic interpretation of sub-surface structures. Current major research projects include tectonic evolution of the Northern Chilean Andes, fold and thrust belts in accretionary terranes, tectonic evolution of deep-water fold belts as well as extensional tectonics and structural evolution of the NW Shelf of Australia.
