The concept of a supercontinent, named "Gondwana, "has stirred the imaginations and stimulated the research of geoscientists since the first suggestion of the possibility of continental drift. The Mesozoic-Cenozoic fragmentation of Gondwana is now reasonably well understood, but the original of the supercontinent is still largely a matter of speculation. Because Gondwana constituted approximately one half of the world's continental crust, the history of assembly of Gondwana is a large part of the history of assembly of "Pangea" near the end of the Paleozoic. Furthermore, the age and sequence of accretion of fragments to Gondwana place important constraints on efforts to decipher the configuration and history of fragmentation of a middle-to-late-Proterozoic supercontinent ("Rodinia"). The principal investigators wish to study the assembly of Gondwana by organizing coordinated research projects that investigate geographic areas and use techniques that are regarded as particularly useful. As a start, they will hold a workshop to identify problems that are both important and require a coordinated approach. They have assembled an international group of scientists with expertise in various geographic areas and geoscience disciplines and will bring them together in the spring of 1993. The primary purpose of this workshop will be to prepare a proposal for further coordinated research projects.

自从第一个关于大陆漂移可能性的建议以来，超大陆的概念（名为“冈瓦纳”）激发了地质学家的研究。 冈瓦纳的中生代 - 共产量碎片现在已经相当理解了，但是超大陆的原始仍然是猜测的问题。 由于冈瓦纳（Gondwana）约占世界大陆地壳的大约一半，因此冈瓦纳（Gondwana）集会的历史是古生代末端附近“ Pangea”组装历史的很大一部分。 此外，冈瓦纳碎片的增生的年龄和顺序对破译中间至中旧生的碎片化的构型和历史的努力对努力构成了重要的限制（“ Rodinia”）。 首席研究人员希望通过组织协调的研究项目来研究冈瓦纳的集会，以研究地理区域并使用被认为特别有用的技术。 首先，他们将举办一个研讨会，以确定既重要又需要协调方法的问题。 他们组建了一群国际科学家，在各个地理领域和地球科学学科中都有专业知识，并将在1993年春季将它们汇集在一起​​。该研讨会的主要目的是为进一步协调的研究项目做准备。
