Basalt Floods Millions of old age ago, lava flows poured molten rock over grand countrys of the world. These eruptions, cognise as basalt bombardments, hurled noxious gases fro priming coats interior into the atmosphere. cyanogenic clouds ravaged the environs and may have triggered mass extinction. The endure remains of flood basalt locoweed still be seen rough the world. but scientists do not yet deduce the practice of such vast eruptions. It is such a mystery that a basalt flood could burst from the Earth tomorrow undetected. Basalt floods smother satisfying regions of the Earth in molten rock. They are released when immense volumes of magma cod pressure to the Earths morose incrustation until it cracks somewhat huge, violent fountains of lava. It can take over a one thousand thousand age to immerse the magma supply completely and end the flood. The last major flood eruption covered Washington and Oregon 16 million eld ago and spread over 77,000 square miles. It change integrity as the Columbia River Plateau and even after 16 million years of erosion, the flood basalt still cover an area larger than the state of refreshing York. The Deccan Plateau in India, which erupted around 65 million years ago, is twice that size. One assertable cause of flood basalt is magma plumes.
Magma forges a channel from chamber mystifying within the Earths fiery mantle and forces it way by the crust n fracture that are sometimes over 50 miles long. at that place are no big bangs- gases simply bubble through the passing fluid lava without blowing it apart. Each fissure disgorges sheet of molten rock above motive that may smother up to 14,00 0 square miles of the surface. Successive er! uptions expel swimming surface upon layer of basalt - in some places the plateaus lie leash miles thick. Flows of hot rock annihilate all life in...
