Single crystal galena pillars as highly anisometric dissolution forms
Published online by Cambridge University Press: 05 July 2018
Abstract
Remarkable single crystal galena formations in the unique form of cylindrical or steep conical ‘pillars’ with ‘capitals’ of small rhombododecahedral single crystals of sphalerite, are described. It is suggested that the pillars result from a highly specific process of anisotropic mineral dissolution controlled by a system of internal channels in the original skeletal crystals and represent a kind of dissolution whiskers.
