The workshop will be convened by Rais Latypov, Steve Barnes and Christian Tegner to commemorate the 50thanniversary of the publication of Wager and Brown’s seminal book. It will provide a comprehensive review and debate of most recent developments in our understanding of a wide range of cumulus and post-cumulus processes operating in mafic-ultramafic layered intrusions. The workshop will immediately precede the 13thPlatinum Symposium and will take place at the Ranch Hotel near Polokwane, South Africa. Attendees will gather on the evening of Wednesday 27thfor a 2-day session on the Thursday and Friday (28-29thof June). On June 30tha one-day field trip to the Eastern Bushveld will be organized that will include visiting the famous Dwars River locality and other interesting stops. We encourage interested attendees to join with the Platinum Symposium to also participate in a session “Petrogenesis of layered intrusions” and related field trips to the Bushveld Complex and Great Dyke.
PRELIMINARY PROGRAM OF OUR WORKSHOP:
Day 1 (Wednesday June 27): Arrival of attendees tothe Ranch Hotel, Polokwane. We aim to arrange transportation from the O. R. Tambo airport in Johannesburg to the Ranch Hotel during the day, but please try to arrive before noon. This is about 4 hour-long drive. Dinner and accommodation are included in the registration costs. There is a possibility to start with a few selected talks during the evening.
Day 2 (Thursday June 28): Processes operating in magma chambers(emplacement, crystallisation, differentiation, solidification, liquid immiscibility, compaction, convection, compositional stratification, slumping and kinetic sieving, erosion, etc.). All meals during the day and accommodation are included.
Evening Great Debate: ”Crystal mushes versus normal/superheated melts in layered intrusions”.
Day 3 (Friday June 29): Case studies of layered intrusions and sills(Skaergaard, Rum, Stillwater, Bushveld, Sudbury, Dovyren, Ilímaussaq, Palisades Sill, etc.). All meals during the day and accommodation are included.
Evening Great Debate: “Topic to be announced”. Your suggestions are welcomed!
Day 4 (Saturday June 30): Bus trip to the famous Dwars River locality, Eastern Bushveld.We will leave after breakfast on two buses (2.5 hours drive) and will spend about 3 hours at the outcrop. A light lunch will be provided in the field. After the trip, one bus will take those who leave back to O. R. Tambo airport in Johannesburg (3.5 hours drive) so expect to be there by about 18.00. Please, plan your flights back accordingly (preferably later than 20.00). Another bus will take those who are staying for the Platinum Symposium back to the Ranch Hotel to the ice breaker party. For this group of people, dinner and accommodation are included in your registration fee to the symposium.
Confirmed presenters for lectures and debates are (in alphabetical order):Alexey Ariskin, Lew Ashwal, Steve Barnes, Chris Ballhaus, Alan Boudreau, Grant Cawthorn, Brian O’Driscoll, Allen Glazner, Marian Holness, Rune Larsen, Rais Latypov, Wolf Maier, Mike Marks, Anders McCarthy, Dick Naslund, Christian Tegner and Ilya Veksler.
A poster session will be organised during both days of the workshop and oral talks are also solicited (subject to time availability). We encourage all participants, especially students, to submit a one-page-long abstract (in free form, but including references) for this session. All abstracts must be submitted to Sofia Chistyakova (Sofia.Chistyakova@wits.ac.za). The deadline for the submission is 9thof March 2018 (as for the symposium itself). The abstracts will be reviewed by organisers of the workshop and notification of acceptance and any other information will be sent to the e-mail address of the person who submitted the abstract by 1stof May 2018. All abstracts and pdf of lectures will be provided to participants electronically before the workshop via the Dropbox.
We have reached a preliminary agreement with the Executive Editor of the Journal of Petrology to publish a thematic volume“Layered igneous rocks: 50 years after Wager and Brown’’to summarise the recent progress in our understanding of layered intrusions. Deadline for the submission is 1stof November 2018. We encourage those who are interested in submitting their manuscripts to this thematic volume to send information on their preliminary topic/title to Rais Latypov (Rais.Latypov@wits.ac.za) by 1stof May 2018.
