| contents | One of the most important geologic discoveries of the 1960s was the remarkable uniformity of the basalts produced at mid-ocean ridges. These basalts have a markedly different tholeiitic composition compared to the alkalic basalts from ocean islands. But very little is known about temporal variations in the composition of basalts derived from one or several mantle sources associated with both normal and anomalously shallow sections of the mid-ocean ridges. The strategy for drilling on DSDP Leg 82 was to set up a broad grid encompassing all possible drilling sites west and southwest of the present Azores Triple Junction in order to investigate these problems. |
