Sedimentation of Halloysite [PDF]

Nature, 1952
IN the North Auckland peninsula of New Zealand there are extensive deposits of halloysitic clays formed by weathering of dacite. Attempts to determine the particle-size distribution of a well-crystallized sample from Matauri Bay, Whakarara Survey District, have revealed anomalous sedimentation behaviour.

Elastic modulus of halloysite nanotubes [PDF]

Nanotechnology, 2013
This work reports measurements of the elastic modulus of halloysite nanotubes. Nanoscale three-point bending tests were performed on individual nanotubes using an atomic force microscope. Nanotubes exhibit elastic behaviour at small deformations. The stiffness of the tubes, and hence their elastic modulus, was deduced from force curve measurements ...

A new microenvironment for the formation of clay minerals: the example of authigenic halloysite-7Å and gibbsite in a stalactite from Agios Georgios Cave, Kilkis, north Greece

International Journal of Speleology, 2015
An unusual authigenic origin for halloysite and gibbsite is reported in a stalactite from Agios Georgios Cave, Kilkis. This speleothem includes mostly pure calcite whereas minor areas of Mg-rich calcite and scarce dolomite are present in four growth ...
