Magma Quotes (3 quotes)
In general, the bigger a mountain the older it is. The biggest mountains were built before any others, because when they were built there was incomparably more flammable material within the Earth. Over the many thousands of years that have passed, the quantity of flammable material has doubtless decreased.
Our earth is very old, an old warrior that has lived through many battles. Nevertheless, the face of it is still changing, and science sees no certain limit of time for its stately evolution. Our solid earth, apparently so stable, inert, and finished, is changing, mobile, and still evolving. Its major quakings are largely the echoes of that divine far-off event, the building of our noble mountains. The lava floods and intriguing volcanoes tell us of the plasticity, mobility, of the deep interior of the globe. The slow coming and going of ancient shallow seas on the continental plateaus tell us of the rhythmic distortion of the deep interior-deep-seated flow and changes of volume. Mountain chains prove the earth's solid crust itself to be mobile in high degree. And the secret of it allthe secret of the earthquake, the secret of the temple of fire, the secret of the ocean basin, the secret of the highlandis in the heart of the earth, forever invisible to human eyes.
The standard of proof is not very high for an investigation that announces that a plume is responsible for a bit of magma or a bit of chemistry found in, or near, or away from a volcano. The standard is being lowered all the time. Plumes were invented to explain small-scale features such as volcanoes. They were 100 kilometers wide. Then they were used to provide magmas 600 km away from a volcano, or to interact with distant ridges. Then the whole North Atlantic, from Canada to England needed to be serviced by a single plume. Then all of Africa. Then a bit of basalt on the East Pacific Rise was found to be similar to a Hawaiian basalt, so the plume influence was stretched to 5000 kilometers! No reviewer or editor has been found to complain yet. Superplumes are now routinely used to affect geology all around the Pacific. This is called creeping incredulity. It can also be called a Just-So Story.
