Dear my Colleagues I would like to draw your attention to an especial issue in Mineralogy and Petrology under title “Gondwana Collision”. In this volume we aim to draw the tectonic evolution of the Gondwanaland and its fragments. Springer offers free color figures to the authors of this issue, so you can publish your paper in color (PDF and hard copy) completely free of charge. In this issue we will discuss the tectonic evolution of the Earth from Rodinia break up to the assembly of Pangaea. The break up and the assembly processes associated with different orogenies (Pan-African, Brasiliano, Adelaidean and Beardmore orogenies) and closure of several major Neoproterozoic oceans (Mozambique Ocean, Adamastor Ocean, Damara Ocean and Trans-Sahara Ocean). All the authors who are working with these orogenies, with Rodinia break up, with Pangaea assembly and with the collision between East- and West-Gondwana are welcome to send their contributions. The deadline to send your contributions is September 15, 2011. The issue will be edited by: Tamer Abu-Alam, Mike Brown, Kurt Stuwe and M. Santosh How to submit your contribution?? 1- If you have an account to Mineralogy and Petrology: you can log to your account (http://www.edmgr.com/mp/submit_manuscript.asp).
