NamibWeb.com - The online guide to Namibia: Brandberg Mountain (621 words) |
 | The Brandberg itself is not a volcano but is a granite plug which was pressed out of the volcano's pipe and stopped at about 10 000 meters under the surface. |
| Rocks forced aside by the upward movement of the intrusion are visible encircling the margin of the Brandberg, tilted sharply upward. |
| Although the Brandberg is not one of the highest mountains in the world, it is the third highest in Africa. |

Brandberg Intrusion, Namibia (243 words) |
| Slightly south and to the west of the Brandberg is the much-eroded Messum Intrusion. |
| Both of these intrusions reflect a period of extraordinarily widespread geological unrest in the Earth's history, which preceded the opening of the Atlantic Ocean and the effusion of vast volumes of basaltic lavas of the Karoo formation that form the Drakensberg plateau. |
| Rocks forced aside by the upward movement of the intrusion are visible encircling the margin of the Brandberg, tilted sharply upward. |
