ALLUVIAl vs ELLUVIAL diamonds can u help?

[keith]

please i'm working on a paper and i need a list of relevant difference
between the two forms of deposits and anyting else you can add.
thank you inmensely

Hi Keith,
There are many experts in this ng, that I'm sure will be able to help you. This
could be a very interesting thread. In addition to Elluvial and Alluvial; why
not Colluvial, and Fluvial, also. Bob

An elluvial deposit (of anything) is material that has weathered
directly from a primary or other hard rock source. A kimberlite on the
side of a hill, and the diamonds shedding down the slope would be an
elluvial deposit. Alluvial, naturally, is a deposit that has undergone
some form of fluvial or marine transport and consequent concentration.

The problem with diamonds is that they are generally is such low
concentrations in a primary source rock that it really unlikely that you
would ever get elluvial deposits. That said, I would regard deflation
deposits with concentrate diamons by virtue of the rest of the material
being removed in some form or fashion as an elluvial deposit. The often
referred to "sedimentary facies" of a kimberlite pipe may well fall into
this category.

Well, I'll give you a hint.

Alluvial relates to transport and/or sorting by water.

Elluvial should be eluvial. Which is the decomposition (weathering)
in place of a rock or ore body.

Hi.. If it's synonymities you're hinting at, then a good reason
why "eluvial and alluvial" shouldn't become "colluvial and fluvial"
is simply that an eluvial deposit means something residual on a
surface, a slope, within the regolith's profile.... Whereas
a colluvial deposit is mainly a briefly transported and redeposited
sediment. There is a difference, though just a slight one from a wider
systems' perspective...
