Illite and smectite both consist of aluminosilicate layers alternating with interlayers. In illite the charge of non-exchangeable interlayer cations is balanced by a greater net negative charge on the ...

Typical SWIR absorption bands of illite are found in the 2000-2500 nm range, and include the 2250 nm, 2359 nm and the 2450 nm features (Fig. 2B). The absence of a feature at 2100 nm points out that ...

A geological survey found that a large deposit of the natural mineral illite has been discovered in Yeongdong County, North Chungcheong Province. Yeongdong County expects it to be the world's largest.

The clay beneath a South Korean wine region contains the world’s largest known deposit of illite, a versatile mineral used in oil drilling, cosmetics, and advanced battery manufacturing. Yeongdong ...

Yeongdong County in North Chungcheong Province announced on the 21st that a joint survey with the Korea Institute of Geoscience and Mineral Resources on the ‘illite mine reserves’ confirmed the ...

The dominance of Illite, which can display a lithium grade comparable to many spodumene deposits, explains the very high grades observed within Bonnie Claire's lithium resource. As earlier analyses ...
