MARGINS Education and Planning Workshop:
Rupturing of Continental Lithosphere in the Gulf of California/Salton Trough region

to be held October 27-29, 2000,
Hotel Camino Real, Puerto Vallarta, Mexico

Convened by: Joann Stock, Arturo Martin and Michael Steckler

A MARGINS workshop on Rupturing of the Continental Lithosphere as applied to the Gulf of California/Salton Trough will be held October 27-29, 2000 at the Hotel Camino Real in Puerto Vallarta, Mexico. Participants in the workshop will examine the application and implications of crustal faulting, strain partitioning, and magma emplacement at a site of active continental rifting where there is a transition to initial seafloor spreading in the Gulf of California/Salton Trough region. The 2 1/2-day workshop, combining US, Mexican and other international expertise, will summarize past and present research on rifting and rifting problems in the Gulf of California/Salton Trough region. In addition, plans for coordinated research and an implementation strategy will be explored at the workshop by the participants, and subsequently passed on to NSF. This approach will provide an opportunity for people to submit competitive proposals to the MARGINS 15 January 2001 RFP, even if they were not originally familiar with the study region. The workshop format will focus on a series of thematic sessions in which the participants can describe, in brief, work in progress, or the work in an early planning stage. Finally there will be a general discussion of what types of modeling experiments and field observations are necessary to address the key research problems and thematic topics presented below.

Key research problems to be discussed during the workshop include:

• mechanisms that allow continental lithosphere to be deformed and the processes that control the evolution of the rift architecture, the nature of transitional crust, and the transition from continental rifting to seafloor spreading;
• horizontal, vertical, and temporal distribution and partitioning of continental extension; o extension style that leads to magma production and distribution and the role of fluid fluxes in facilitating extension and extension style;
• relationship between extension style and distribution to the stratigraphic evolution of the rift basin.

Key thematic topics to be discussed during the workshop include:

• On-land geological investigations around the Gulf of California/Salton Trough region
• On-land geophysical investigations around the Gulf of California/Salton Trough region o Marine geophysical studies in the Gulf of California:
• Cross-disciplinary studies
• Theoretical studies

Puerto Vallarta is a port city on Banderas Bay in the state of Jalisco, just south of the mouth of the Gulf of California. The Hotel Camino Real has been the headquarters hotel for the yearly meeting of the Union Geofisica Mexicana (Mexican Geophysical Union) for the past few years, and will be the site of Mexico's 2nd National Earth Sciences Meeting immediately following the MARGINS workshop. If participants wish to stay for this meeting, further information can be obtained from http://www.ugm.org.mx/reunion2000i.html.

Participants will need to arrive in Puerto Vallarta on Friday, Oct, 27, and if not attending the Mexican meetings, depart on Monday Oct. 30. The meeting will take place Friday evening and all day Saturday and Sunday, Oct. 28 and 29. Simultaneous translation of all English and Spanish talks and commentaries will be available to enhance communication and collaboration. Applications to attend the workshop should be submitted to the MARGINS Office no later than Sept. 8, 2000. Funds to cover lodging and meals are available; funds are also available to defray partial travel costs, particularly for US participants.

Applicants should send an e-mail message to margins@ldeo.columbia.edu containing (1) address, (2) a short description of their research, and (3) a one-page abstract for the meeting, which will be translated as necessary and distributed in both languages at the workshop.

Inquiries may be addressed to the MARGINS Office (http://www.ldeo.columbia.edu/margins) or directly to the conveners; Joann Stock (jstock@gps.caltech.edu), Arturo Martin (amartin@cicese.mx) or Michael Steckler (steckler@ldeo.columbia.edu).

AGU Town Meeting: The Nankai Subduction Zone, southwest Japan

Friday, 15 Dec., 2000 5:30-8:00 PM Rooms 270 & 272, Moscone Center. Refreshments Provided.

The Nankai subduction zone produced destructive great earthquakes in the 1940's and remains a significant societal hazard. It is one of the focus areas of the Seismogenic Zone Experiment (SEIZE) (http://www.soest.hawaii.edu/margins/SeismZone.html) and the locale of intensive recent geophysical and geological investigations. In order to inform the community about on-going projects, to highlight outstanding problems, and to encourage new collaborations we are sponsoring a discussion of current and planned research in the Nankai subduction zone. We will briefly review current 3D seismic reflection, Ocean Bottom Seismometer, and GPS programs plus recently completed and planned ODP drilling. We will follow with short presentations from the floor on current or planned research in the Nankai subduction zone and end with a freeform general discussion.

We invite all interested geoscientists to come, listen, and contribute. We are especially interested in attracting new collaborators with scientific approaches and agendas not currently being pursued.

The Geologic and Climatic Evolutionof the Arabian Sea Region

Geological Society of London Burlington House, Piccadilly, London, UK, 5-6th April 2001

A joint meeting of the Marine Studies, Tectonic Studies and Petroleum Groups of the Geological Society.

This meeting will review current research on the geologic, climatic and paleoceanographic evolution of the Arabian Sea region. This region is one of dramatic current and past tectonic and climatic activity. It may be considered the world's type area for studying tectonic-climatic interactions, where orogenic uplift has been linked to the intensification of the SW Asian Monsoon. Since the Indus fan drains the high topography of western Tibet, the Karakoram and Himalaya, whose development is proposed to have initiated the SW Monsoon, linked models can be tested in the sedimentary records of the region.

The aims of the meeting and subsequent special publication will be to synthesize data from the diverse subdisciplines that are examining this region in order to better understand how the system as a whole operates. We envisage that this meeting will not only address the marine geology and geophysics, but also the development of the onshore areas surrounding the sea, since these regions have had a profound effect on the development of the oceanic crust and continental margins,e.g., the onset of nature and timing of upwelling along the Oman margin, the nature and source of sedimentation on the Indus Fan and in the Gulf of Oman, as well as tectonic uplift of the Murray and Owen Ridges.

The meeting will also be of interest to the hydrocarbon industry which is currently exploring in the shelf areas of Pakistan and India and is seeking opportunities in the deep water slope areas of this relatively unexplored rifted volcanic margin.

The results of the meeting will be published as a special publication of The Geological Society. Abstracts and suggested talk titles should be submitted to the convenors at the earliest opportunity.

Abstract deadline, 1st December 2000.
