Khatika
According to vachaspatya
Kahatika is defined as “लेखनसाधनद्रव्यभेदे”
Chalk is a variety of limestone composed mainly
of calcium carbonate derived from the shells of tiny marine animals known as
foraminifera and from the calcareous remains of marine algae known as coccoliths.
Chalk is usually white or light gray in color. It is extremely porous,
permeable, soft and friable.
How
Does Chalk Form
When
foraminifera, marine algae, or other organisms living on the bottom or in the
waters above die, their remains sink to the bottom and accumulate as ooze. If
most of the accumulating organic debris consists of calcium carbonate, then
chalk will be the type of rock that forms from the ooze. However, if
the accumulating organic debris comes from diatoms and radiolarians, the ooze
will consist mainly of silica, and the rock type that forms will be diatomite.
Extensive deposits
of chalk are found in many parts of the world. They often form in deep water
where clastic sediments from streams and beach action do not dominate the
sedimentation. They can also form in epeiric seas on continental crust and on
the continental shelf during periods of high sea level.
Identifying Chalk
The keys to identifying chalk are its hardness, its fossil content,
and its acid reaction. At a glance, diatomite and gypsum
rock have a similar appearance. An examination with a hand lens will often reveal the fossil content, separating it
from gypsum. Its reaction with dilute (5%)
hydrochloric acid will separate it from both gypsum and diatomite.
