Expanding Geospheres [signed] [first edition]

A new theory of the earth is explored in which diverse phenomena, such as the Earth's zonation into geospheres, igneous endogeny and tectonics, are attributed to volatile emanations from inner Earth. The "granite problem" is finally resolved. The polonium-halo problem is resolved. The generation of petroleum and metallic ores become comprehensible, and the location of a potentially huge hydrocarbon resource is described.
