On the Mohs Scale of Hardness, chert has a hardness of 7.
i think rocks are scaled differently because they can have several different compositions
and thus vary in hardness
Diagnostic features would include a Mohs hardness of around 7, conchoidal fracture, and extremely fine grained texture.
Chert has no streak, it is too hard.
It is not uncommon to find masses and layers of chert within deposits of limestone.
Chert is actually not a mineral. Chert is a type of sedimentary rock that is made up of many minerals. It is composed mainly of the minerals chalcedony and quartz.
You can find chert at daly spur just south of dillon mt.

No.
They are all igneous, except chert
You can find chert at daly spur just south of dillon mt.
Chert is usually found in the form of nodules or lenses in bodies of limestones or dolomites.
Chert can be used as an abrasive, used to make glass, and used to make gemstones.
