| 41. | By comparison, the oldest dated continental crust is.
|
| 42. | The magma was contaminated with continental crust material.
|
| 43. | The rise most probably originates from subsided continental crust that fragmented as Australia and Antarctica separated.
|
| 44. | Sill-like intrusions of basalt into lower continental crust.
|
| 45. | But even as the debate over ancient continental crust heats up, the terrain itself is cooling.
|
| 46. | It is now known that there are two kinds of crust : continental crust and oceanic crust.
|
| 47. | Thus incompatible elements are those that are enriched in the continental crust and depleted in the mantle.
|
| 48. | The Cameroon volcanic line is geologically unusual in extending through both the ocean and the continental crust.
|
| 49. | Delamination occurs when the lower continental crust and mantle lithosphere break away from the upper continental crust.
|
| 50. | It is thought that the melting and reworking of oceanic crust formed the early Archean continental crust.
