A rare mineral variety, possibly related to white or pale-colored mineral deposits with uncertain composition.
Likely a mineralogical naming combining 'alw' (possibly referencing 'all' or a location) with the mineral suffix '-ite,' though the exact etymology is unclear and may be obsolete.
Some mineral names are so obscure that even geologists have trouble confirming what they actually are—'alwite' might be a ghost name, a mineral that got named but then forgotten or reclassified!
