sup 40 Ar/ sup 39 Ar age and duration of tholeiitic magmatism related to the early opening of the Red Sea rift
The early opening of the Red Sea rift is accompanied by tholeiitic magmatism stretching at least 1,700 km along the western coast of Saudi Arabia, and consisting of thick gabbroic dykes, dense dyke swarms, plutons and discrete lava flows. Whereas the conventional K-Ar measurements have furnished a w...

| description | The early opening of the Red Sea rift is accompanied by tholeiitic magmatism stretching at least 1,700 km along the western coast of Saudi Arabia, and consisting of thick gabbroic dykes, dense dyke swarms, plutons and discrete lava flows. Whereas the conventional K-Ar measurements have furnished a wide variety of ages, the {sup 40}Ar/{sup 39}Ar analyses presented here (giving 17 plateau-ages) display a pronounced cluster of ages from 24 to 21 Ma. Such a short-lived magmatic event has been suggested for other continental rifts. |
