Sericite is name given to very fine, ragged grains and aggregates of white mica – usually muscovite – produced by the alteration of feldspars or other minerals. Included grains of zircon …

Sericite is a common alteration mineral of orthoclase or plagioclase feldspars in areas that have been subjected to hydrothermal alteration typically associated with copper, tin, or other …

Sericite is produced by the alteration of orthoclase or plagioclase feldspars in areas that have been subjected to hydrothermal alteration (also see Sericitic alteration) typically associated …

Alteration zones in Onzon-Kanbani area can be generally described as three types of alterations: silicic (banded and crustiform banding), sericite-illite and porpylitic alteration (Fig.6) on the...

When observed under the microscope, the sericite laminae are less than 0,01 mm thick and composed of individual sericite grains, suggesting that these were an originally laterally …

Fe-rich chromite is typically opaque at full thin section thickness, but is transparent dark-brown along thin edges. The chromite shown here is relatively Fe-poor. Chromite is isotropic, like all …

2023年4月23日 · Sericite is a type of mica, specifically a muscovite mica. The chemical formula for sericite is KAl2(AlSi3O10)(OH)2, which means it contains potassium, aluminum, silicon, …

micROCKscopic.ro makes Optical Mineralogy and Petrology be easier to examine a thin section and to understand the characteristic properties of each mineral/rock without a petrographic …

Sericite grains are too small to see in hand specimens and it is transparent with only moderate relief when viewed in thin-section in plane polarised light. With polars crossed, its medium to …
