2. Diatomite
is a chalk-like, soft, friable, veryfine-
grained siliceous sedimentary rock that
is light in colour (white and yellowish) white if pure,
commonly buff to grey in situ.
• It is composed of fossilised remains of unicellular
aquatic algae-like plants called diatoms which are
both marine & lacustrine in origin. Diatoms are
microscopic, singlecelled organisms, often
appearing as colonial aquatic plants (algae).
• Diatom cells contain an elaborate internal
siliceous skeleton. More than 10,000 living diatom
species have been identified, in addition to
another 10,000 known diatom fossil forms.
• Diatomite deposits are the remains from the cell
wall of diatoms,which are composed of
amorphous hydrous silica.
