73) may be suggestive of likely hosting of crandallite
mineral group for Sr.
Their interiors, when broken open, revealed porous, earthy masses of whitish material we guessed to be crandallite
(known at that time as pseudowavellite).

The mineral (accompanied by crandallite
, its alteration product) forms free-standing, doubly terminated crystals to 1 cm, in aggregates associated with manganese and iron carbonates (siderite, ankerite, rhodochrosite) or quartz.

is common in a mixture with variscite as part of agate-like phosphate concretions.
The minor amounts of crandallite
and millisite in Christmas Island A-ore became amorphous.
Relationship to other species: It is a member of the crandallite
group and the [Fe.
Llallagua phosphates, including childrenite, crandallite
, fluorapatite, metavauxite, monazite, paravauxite, sigloite, vauxite, vivianite and wavellite, were actively collected by Bandy.
Other minerals present in attractive, smaller crystals or coatings include cacoxenite, crandallite
, dufrenite, gypsum, jarosite, native selenium and strengite/variscite.
Relationship to other species: A member of the crandallite
Some of the minerals occurring at the Mex-Tex mine (coronadite, crandallite
, creedite, libethenite, plumbogummite, tsumebite and turquoise) have not been found at the Blanchard mine or elsewhere in the district.
