Where chlorite is important, it is sometimes called chloritic or "propylitic" alteration.
Mica, epidote, and chlorite are also present as accessories.
Red limestones usually contain haematite; in green limestones there may be glauconite or chlorite.
In igneous rock the ore-bearing solutions may have altered the wall rock to a dense mixture of quartz, sericite, and chlorite.
Unless the powder be fresh made, a portion of chlorite is always converted into chloride of calcium.
I did feel that I did not owe my escape merely to my acquaintance with chlorite and its properties.
chlorite is another soft, easily scratched mineral, generally of a dark-green colour.
The three last-mentioned minerals—talc, serpentine, and chlorite—are all silicates of magnesia.
Melaphyre is a name given to the very dark varieties of altered augitic lavas, rich in magnetite and chlorite.
Veins of quartz, tourmaline and chlorite may traverse the granite, containing tinstone often in workable quantities.
chlorite chlo·rite2 (klôr'īt')
A salt of chlorous acid.
The inorganic group ClO2 or a salt containing it.
|chlorite 1 |
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.
