Proterozoic East Gondwana: Supercontinent Assembly and Breakup Geological Society Special Publications Society Book Editors R. J. PANKHURST (CHIEF EDITOR) P. DOYLE E J. GREGORY J. S. GRIFFITHS A. J. HARTLEY R. E. HOLDSWORTH A. C. MORTON N. S. ROBINS M. S. STOKER J. P. TURNER Special Publication reviewing procedures The Society makes every effort to ensure that the scientific and production quality of its books matches that of its journals. Since 1997, all book proposals have been refereed by specialist reviewers as well as by the Society's Books Editorial Committee. If the referees identify weaknesses in the proposal, these must be addressed before the proposal is accepted. Once the book is accepted, the Society has a team of Book Editors (listed above) who ensure that the volume editors follow strict guidelines on refereeing and quality control. We insist that individual papers can only be accepted after satis- factory review by two independent referees. The questions on the review forms are similar to those for Journal of the Geological Society. The referees' forms and comments must be available to the Society's Book Editors on request. Although many of the books result from meetings, the editors are expected to commission papers that were not pre- sented at the meeting to ensure that the book provides a balanced coverage of the subject. Being accepted for presentation at the meeting does not guarantee inclusion in the book. Geological Society Special Publications are included in the ISI Science Citation Index, but they do not have an impact factor, the latter being applicable only to journals. -

Isotopic Evidence on the Age of the Trysil Porphyries and Granites in Eastern Hedmark, Norway
ISOTOPIC EVIDENCE ON THE AGE OF THE TRYSIL PORPHYRIES AND GRANITES IN EASTERN HEDMARK, NORWAY by H. N. A. Priem1), R. H. Verschure1), E. A. Th. Verdurmen1), E. H. Hebeda1) and N. A. I. M. Boelrijk1) Abstract. Rocks from the (sub-Jotnian) acidic plutonic and volcanic basement complexes in the Trysil area, eastern Hedmark, yield a Rb—Sr isochron age of 1 541 ±69 million years. This agrees within the limits of error with the isochrom age of 1590 ±65 million years determined for the Dala porphyries and granites in Dalarna, Sweden, which are the continuation of the acidic igneous complexes in the Trysil area. The sub-Jotnian acidic magmatism in the eastern Hedmark—Dalarna region can thus be dated at 1570 ± 40 million years ago, i.e. some 100 million years younger than the termination of the Svecofennian orogcny. (Ages computed with A. = 1.47 x 10"11 yr"1 ; errors with 95 % confidence level). Chemically, this magmatism is characterized by a granitic to alkali granitic and alkali syenitic composition. The Trysil area has also been affected by a tectonothermal event in Sveconorwegian time, about 925 million years ago, as evidenced by the Rb—Sr and K—Ar ages of separated biotites. Introduction. Studies on the geology of the Trysil area in eastern Hedmark have been published by Schiøtz (1903), Reusch (1914), Holmsen (1915), Holtedahl (1921), Dons (1960) and Holmsen et al. (1966). The Quaternary deposits were mapped by Holmsen (1958, 1960). A geo logical sketch map of the area is shown in Fig. 1 (mainly after the Geo logisk Kart over Norge, 1960). -
