Halloysite-10Å

This page is currently not sponsored. Click here to sponsor this page.
Jean-Baptiste-Julien d'Omalius d'Halloy(1783-1875)
Formula:
Al2Si2O5(OH)4 · 2H2O
System:
Monoclinic
Name:
Named after the Belgian geologist Jean-Baptiste d'Omalius d'Halloy, (February 16th 1783 - January 15th 1875), who discovered the mineral. He was a nobleman, a statesman, and pioneer of modern geology in Belgium. The 10-Å(ngström) refers to the layer thickness.
Note: halloysite-10Å is not a polytype of halloysite.
It is an approved (grandfathered) species distinct from halloysite-7Å which does not contain molecular water.

Synonyms are "endellite" (name for halloysite-10Å in European literature; discredited in 2006), "hydrated halloysite" and "hydrohalloysite."
Further localities are listed under "endellite".



Classification of Halloysite-10Å
