for the membership
of IAGR
international Association for Gondwana Research (IAGR) is an association of scientists who are involved in Gondwana earth science research. The provisional membership fee for IAGR is 20 dollars for scientists from developed countries and 5 dollars for those from developing countries. The Gondwana Newsletter (twice a year) is sent free to members, who also may have the privilege of getting information and special services related to Gondwana Research (e.g. concession rates for the association journal, memoirs, and publications by the Gondwana Research Group at a reduced price). We would like to cordially request you to enroll as a member of the IAGR. Applications for membership should include: name, date of birth, affiliation, address and field of scientific activity including important contributions. For further details please correspond to: Prof. M. Yoshida, whose complete address is given in the last page of this Newsletter.
Call for contributions
to the Gondwana
Newsletter The Gondwana Newsletter (GN) is published twice a year and provides an excellent media for updating current research activities in various Gondwana continents. The response to GN has been quite encouraging. We invite short articles (not exceeding three printed pages including references, tables and figures; longer correspondence will be subjected to review), write-ups on new projects, announcements, notes, conference reports, interesting articles in journals etc. Address all your correspondence to the editorial offices of GN.
