Role of content and crystal chemistry of analcime on cation exchange capacities of analcime rich rocks

, 2023
International audienceThe Abinky sedimentary formation is composed of analcimolites (i.e., rocks with more of 70 wt% of analcime) that underlies the Tchirézine 2 (Tchi2) formation, known for hosting the Imouraren uranium (U) deposit (Niger).

THERMODYNAMIC PROPERTIES OF ANALCIME SOLID SOLUTIONS.

American Journal of Science, 2004
Analcime (NaxAlxSi3-xO6 . [(3-x)/2]H2O, where x varies from similar to0.78 to similar to1.06) is one of the most common rock-forming zeolites. It forms in a wide range of geologic environments that span a range of temperature and pressure from ambient to
