1. His doctoral thesis was a petrologic study of the Boxelder laccolith . 2. There is likely to be a giant laccolith of syenite below Cygnet. 3. The laccolith ranges are much younger and have a very different geologic origin. 4. Geologically, the mountain is a laccolith , dating from the Cenozoic era. 5. Craigleith is a laccolith , a lava dome. 6. Laccolith formations are caused by igneous activity otherwise known as melting within the earth.7. The rock is a thick gabbroic-dolerite laccolith , which is a source of roadstone. 8. The Mount Kinabalu intrusion is a laccolith where intrusion of magma pushes up into the stratigraphy. 9. Instead of a mushroom cloud, how about a mushroom laccolith under the volcano's base? 10. The Mount Kinibalu intrusion is a laccolith style pluton that caused the deformation of sediments overlying the intrusion.
