VERY INTERESTING!! The genesis of plumes in agates has been hypothesized to be bacterial in origin. It is the result of biomineralization by biofilms of extremophile bacteria. Living analogues have been discovered in a number of today’s environments. The gelatinous consistency of the agate that was forming was a perfect substrate for the proliferation of these colonies within the agates. So we can say that plumes are more a fossil than a mineral. You can find more information about the bacterial life within agates and other minerals in the book “Biominerals” (Campos-Venuti, 2022).
