Hi Chris. Until now I had never heard the word “igneous geosphere” It appears that it is derived from two words.

Igneous

Of, relating to, or characteristic of fire. Geology.
Formed by solidification from a molten state. Used of rocks.
Of or relating to rock so formed; pyrogenic.
[From Latin igneus, from ignis, fire.]

Geosphere

The geosphere is the solid Earth that includes continental and oceanic crust as well as the various layers of the Earth's interior. Ninety-four percent of the earth is composed of the elements oxygen, iron, silica, and magnesium, and the interior of the earth is layered both chemically and mechanically. The geosphere is not static, but its surface (crust) is in a constant state of motion that gives rise to movement of the continents. The unifying theory that explains how continental drift is possible is called plate tectonics, which was developed by geologists in the 1960s.

I will continue to accept what Lowell or anyone else has to say as long they can demonstrate there is a possibility. It’s only when someone presents me something and expect me to believe it without ever presenting one shread of evidence that I reject something, or at the very least put it on the back burner.
