Summary:

"The conference program was designed to cover many aspects of the five major mass extinction events and their hypothesized causes ranging from impacts and large igneous provinces to other environmental causes. This multi-disciplinary conference succeeded in bringing together 150 researchers, including seasoned experts as well as younger researchers and students in geology, geophysics, geochemistry, volcanology, sedimentology, paleontology, and astronomy. A new, collaborative, multi-disciplinary approach to resolving outstanding problems was explored through listening and learning from each other and by spirited, constructive discussion. The data and concepts presented and discussed at the meeting, and published in this Special Paper, have value well beyond the geosciences, particularly with regard to understanding modern environmental crises. The main conclusions of this conference were: [1] Large igneous province volcanism, along with associated climate and environmental changes, is likely to have played a significant role in at least four of the five major mass extinctions in Earth history ... [2] There was overwhelming agreement that a single large asteroid impact (Chicxulub) could not have been the sole cause of the end-Cretaceous mass extinction, but rather was a contributing factor ... [3] Participants gained an improved understanding of how large igneous province eruptions affect the biosphere ... [4] Mass extinction patterns can tell us much about the age, tempo, and nature of the catastrophe and the type of environments that were most affected ... [5] Ultimately, the effects of volcanism, impacts, sea-level and climate changes (warming and cooling), ocean acidification, ocean anoxia, and atmospheric changes have to be considered in any extinction scenario in order to understand the causes and consequences of mass extinctions ..."--Foreword.
