Mixed/Hybrid Systems (Turbidite, MTDs and Contourites) on Continental Margins

F. Javier Hernández-Molina, Karyna Rodriguez & Neil Hodgson

18-19 May 2022
  |  
Lisbon, Portugal

Sediment gravity flows and along-slope bottom currents (contourites) are the two main deep-water sedimentary processes shaping the continental margins and controlling the stacking patterns of their sedimentary successions. Depending on which one of these processes dominates, either a pure mass transport deposit (MTD), turbiditic or contourite depositional systems develop. But, when these processes interact each other, a hybrid or mixed depositional systems are generated. These hybrid systems are characterized by a wide spectrum dominated by either along- or down-slope processes forming morphological features and deposits which deviate away from end-member models. These hybrid systems have only just been recently identified but due to their economic importance proven by recent significant discoveries (Coral and Mamba Fields, Mozambique and Jubilee Field, Ghana) they have begun to be studied in more detail.

Examples of hybrid / mixed depositional systems have been described in the offshore of Mozambique, Uruguay, Brazil, Argentina and Antarctica. In spite of these examples and their importance, there is a lack of knowledge about these systems themselves and the nature of processes interaction at the base of their origin. Similarly, the role of bottom-currents in the redistribution and reworking of deep-water sediments forming contourite systems, has been clearly underestimated. The diagnostic criteria to identify them at the facies and seismic scales in relation to sediment gravity flows deposits is still missing and the paleoceanographic implications are unknown. The interaction of processes promotes the deposition of clean sandstone deposits as a result of vigorous bottom currents, or due to the reworking of overspill sediments in both canyons/channels and inter-channel areas, which have renewed interest and attention from both academia and the exploration industry which should result in providing insights into a great future exploration opportunity.

Mixed/Hybrid Systems (Turbidite, MTDs and Contourites) on Continental Margins - Call for Abstracts Ends on 20 December, 2021

You are invited to submit a abstract presentation proposal. Please complete and submit the abstract by 20 December 2021.

Abstract Submission Guidelines
  • Abstracts should cover the objectives, procedures, results and conclusions of the research and should be no more than 2,500 characters in length including spaces and punctuation. The title, authors, and authors’ affiliations are not included in the character limit. Abstracts can include 2 figures, to be included in the document and uploaded separately for quality purposes.
  • Titles are required—they should be brief and state the topic.
  • Abstract titles should not include company names.
  • If your abstract requires company approval, please start the process immediately.
  • In keeping with the spirit of the workshop, presenters must refrain from making subtle or blatant sales pitches including but not limited to: repeated use of product names, trade names, or pictures, or repeated use of company logo.
  • Evaluation and ranking of abstracts are based on relevance and timeliness of subject matter; usefulness of contribution to the advancement of knowledge, techniques, or practice; and overall clarity, organization, and presentation of ideas. The Technical Program Committee is seeking abstracts with direct application to industry.
  • Sessions will be determined from the abstracts submitted to each theme. Sub-themes may not directly correspond to sessions in the final program.
  • Submit your abstract in the form in which you would like it published. Abstracts will not be edited.
  • Authors will be notified of acceptance or rejection in early February 2022.
  • Authors are invited to have their work, both oral and poster presentations, published on AAPG’s online Search and Discovery to preserve their work for future reference. We will need your permission to do it so.
  • Posters will be presented in coffee breaks sessions. The poster booth will consist of one A0 size panel in Portrait mode

Important: AAPG has no funding for speakers. Do not submit an abstract unless at least one author is certain to attend the convention. All session chairs, speakers, and poster presenters must register to attend the convention — no exceptions.

  • Bottom current processes & deposits (including bottom-current reworked sands, BCRS)
  • Hybrid / mixed depositional systems
  • Synchronous vs asynchronous interactions
  • Numerical models & tank experiments
  • Ichnological analysis of turbidite, MTDs, contourite and hybrid / mixed deposits
  • Data integration & multidisciplinary analysis
  • Implications on hydrocarbon exploration
Invited talks

Note:Transportation to start point is not included in the costs of this trip. Please bring clothing for hot day time temperatures (sun hat/ sun glasses/ sun cream etc.). Participants must wear suitable and comfortable light trekking shoes.

Aims

To gain or increase an understanding of the tectono-sedimentary processes of continental extension and rifting supported by outcrop observations, with focus on deep-depositional marine systems. Discuss implications for prospective petroleum systems. Promote debate and nourish new insights between attendants.

About the Field Trip

The Lusitanian Basin records the proximal events of syn- to post rift evolution of the hyper-extended West Iberian Margin, showing some outstanding examples of the combined tectono-stratigraphic depositional systems. Here, the Late Jurassic reveals diverse aspects of mixed marine depositional systems including not only submarine fans and turbidites, but also the build-up of carbonate reefs and shoreface to fluvial clastic sequences. Throughout the fieldtrip the different depositional aspects can be observed in detail to demonstrate how such depositional systems can vary in time and space. Observation of these outcrops allows a better understanding on how deep-water depositional systems can change within a sub-basin and help improving the understanding of reservoir properties.
