ORIGIN OF THE PHOSPHATE-ROCKS, 
AND FORMATION OF THE 
PHOSPHATE-ROCK BASINS. 
If the reader has followed us in the attempt to 
make plain the order of superposition, and the prom- 
inent characteristics of the geological formations as 
described in the foregoing pages, he is now prepared 
to go with us also into a consideration and examina- 
tion of the origin of these rocks, and their remarkable 
position, as seen in the Charleston Basin. 
And first, we should always bear in mind this 
important fact: that though these Basins were formed 
in the Post-Pleiocene age, the vocks deposited in them 
do not actually belong to that age, but in fact, to the 
Eocene an older formation. It has been ascertained 
beyond doubt, that frequently, rocks or fragments of 
rocks of older formations and therefore of greater 
age are found in newer deposites of a comparatively 
recent date. Quartz-pebbles, and fragments of water- 
worn crystalline rocks are often seen imbedded in 
modern clays and sands. The Phosphate-rocks of 
these basins, like the Quartz-pebbles, just named,
