[8] Both nickel-bearing talc and nickel dominant smectite occur at the type locality, Szklary, Ząbkowice Śląskie County, Lower Silesia, Poland.
[3] Pimelite apparently constitutes part of the mixtures called garnierite or noumeite, and it could form a series with stevensite or saponite.
The tetrahedral sheets comprise (Si,Al)O4 tetrahedra, linked together in nearly hexagonal rings.
[3] Pimelite is found in lateritic nickel ore deposits above serpentinites or dunites, frequently mixed with nickel-rich serpentine minerals or quartz.
A nickel silicate hydroxide mineral was first described from Franklin, New Jersey, in 1889, but it has not been reported from the neighbouring Sterling Hill.
It was originally called desaulesite, for Major de Saules, manager of the Trotter Mine at Franklin, but that name is now used for zinc-rich garnierite.
[8] Pimelite from the Trotter Shaft occurs as localized, patchy, thin crusts and dense 1 to 6 cm masses as an alteration product of nickel arsenides.
