Endeavour, 1964 AbstractThe zeolites form a numerous group of structurally diverse, porous, crystalline aluminosilicates. The naturally‐occurring zeolites arise by hydrothermal action of solutions in basaltic rocks and also as large sedimentary deposits. The naturally‐occurring species have been augmented by a number of synthetic zeolites without any known natural ...
