Abstract

Two main types of passive margins known as volcanic and non-volcanic rifted margins, based on the extent of volcanic activity associated with their formation, are widely recognised. Volcanic rifted margins have now been identified along the edges of many continents (Coffin & Eldholm, 1992) and cannot any longer be considered as rare exceptions to 'normal' (non-volcanic) continental break-up.

Highlights

Two main types of passive margins known as vo1canic and non-vo1canic rifted margins, based on the extent of volcanic activity associated with their formation, are widely recognised
In 1993 these activities continued with site surveying for future aDP drilling at the South-East Greenland margin in August-September, and Leg 152 of the Ocean Drilling Program completed the first of two planned drilling legs at this margin in September-November (Fig. l)
While the primary objective of the margin study is the fundamental process of break-up, considerable important information on the subsequent sedimentation along the margin can be obtained through both the high-resolution seismic surveying and the drilling
