[HTML][HTML] Chlorite in sandstones
Abstract Chlorite, an Fe-and Mg-rich aluminosilicate clay, may be either detrital or authigenic
in sandstones. Detrital chlorite includes mineral grains, components of lithic grain, matrix …

[PDF][PDF] Low-temperature chlorite geothermometry: a graphical representation based on a T–R2+–Si diagram
The chlorites are good indicators of rock history because their wide compositional variations
are sensitive to the formation conditions, like pressure (P), temperature (T), redox state, fluid …
