The detrital phase is composed of eolian debris and volcanogenic debris eroded from submarine outcrops by bottom currents. The phosphate phase is not clearly distributed with latitude, longitude, or the equatoria

The first successful deep boring took place at Funafuti Atoll during 1896–1898, though it failed to reach reef foundations. Darwin’s theory was not demonstrated to be correct until more than 110 years after those first tent
