Historical Examples of chloritic
This marly deposit passes in its turn into beds containing green particles of a chloritic mineral, called the upper greensand.A Manual of Elementary Geology
The ore is found in a sort of chloritic slate and iron pyrites which follow the ledge all around.
Above the Chert beds is a band a few feet thick known as the Chloritic Marl, which shows a passage from sand to calcareous matter.The Geological Story of the Isle of Wight
J. Cecil Hughes
The green colour is due to a chloritic mineral; the red to haematite.
- any of a group of green soft secondary minerals consisting of the hydrated silicates of aluminium, iron, and magnesium in monoclinic crystalline form: common in metamorphic rocks
Word Origin for chlorite
- any salt of chlorous acid, containing the monovalent ion ClO 2 –
- A salt of chlorous acid.
- The inorganic group ClO2 or a salt containing it.
- A usually green or black, flaky mineral that looks like mica. Chlorite is either monoclinic or triclinic and occurs in low-grade metamorphic rocks (rocks that have undergone little metamorphism). It often forms by the alteration of dark minerals (often rich in iron and magnesium) during metamorphism. Chemical formula: (Mg,Fe,Al)6(Si,Al)4O10(OH)8.
- A salt containing the group ClO2.
