Phillipsite-Ca
Phillipsite-Ca is a hydrated calcium silicate mineral belonging to the heulandite subgroup of the zeolite family. Its chemical formula is Ca3(Si10Al6)O32·12H2O, indicating a complex structure with silicon, aluminum, oxygen, and water molecules. It crystallizes in the monoclinic system and is characterized by a vitreous luster, a hardness of approximately 3.5 to 4 on the Mohs scale, and a relatively low density. The mineral typically exhibits a white to colorless appearance and is commonly found in low-temperature hydrothermal environments. It is classified under the Strunz system as 9.GC.10, reflecting its zeolite group membership.

Overview
Phillipsite-Ca is a hydrated calcium silicate mineral belonging to the heulandite subgroup of the zeolite family. Its chemical formula is Ca3(Si10Al6)O32·12H2O, indicating a complex structure with silicon, aluminum, oxygen, and water molecules. It crystallizes in the monoclinic system and is characterized by a vitreous luster, a hardness of approximately 3.5 to 4 on the Mohs scale, and a relatively low density. The mineral typically exhibits a white to colorless appearance and is commonly found in low-temperature hydrothermal environments.

Etymology
Phillipsite-Ca is named after the element calcium, which is a key component of its chemical composition. The mineral's name reflects the presence of calcium in its structure, distinguishing it from other members of the phillipsite group.
How to recognize it
Phillipsite-Ca can be identified by its low hardness of 3.5 to 4 on the Mohs scale, which is relatively soft for a silicate mineral. It typically appears white to colorless and has a vitreous luster. A streak test will yield a white streak. Its low density and monoclinic crystal system help distinguish it from other zeolites. It is often confused with other phillipsite varieties or similar zeolite minerals due to overlapping physical properties.
Host rocks
As a member of the zeolite group, phillipsite-Ca is typically found in low-temperature hydrothermal environments, such as in cavities of basaltic or other volcanic rocks. It may also occur in sedimentary or metamorphic rocks where conditions favor zeolite formation.
