The tholeiite basalt series can be produced by two parental melts: aluminous and magnesian basaltic, both separated from the mantle sources via the filter pressing mechanism: the former at depths shallower than 30 km in ocean spreading zones (TOR-2), and the latter at depths of 50鈥 60 km ...
Despite our ability to populate almost all parts of the world, Mother Nature is still pretty good at keeping a few secrets from humans. But with every new trek into uncharted rainforests or further into the depths of the seas, we're still able to meet animals that are totally new to us...
So, does the spreading of the ocean floor mean that the surface of the earth is increasing? No, not in the least. Sea floor spreading doesn’t cause an increase in the earth’s surface. And why not? Because the lava that rises and spreads from the oceanic ridges sinks again elsewhere ...
Other than the massive channels they carved, the long-term outcome of these massive outflows of water are unclear. Some scientists believe that these water outflows led to a temporary Hesperian ocean that quickly glaciated. Others counter that this outflow period (which lasted around 1 billion ...
