“The absence of euhedral crystals of phillipsite, even by SEM examination, suggests that the alteration may be a form of pseudomorphism.”

“Although this is not a particularly quantitative test, it does show that complete pseudomorphism had not occurred for these two specimens.”

“Powell also falls into the trap of pseudomorphism, but she is unashamed of it.”

“The most common secondary uranium mineral at the mine, it is typically associated with sooty black organic material and may pseudomorph it.”

“In the formation of a pseudomorph by substitution, the original substance has been gradually removed and simultaneously replaced by another.”

“It is sometimes found as a pseudomorph of sérandite crystals usually coated by a very fine dark green powdery chlorite-group mineral.”

“At some locations sericite completely pseudomorphs topaz and the feldspars.”

“They noted that good pseudomorphs of limonite after pyrite, both as cubes and as pyritohedra, are common, especially in bodies of massive pyrite.”

“Copper pseudomorphs after another isometric mineral, apparently cuprite, are known in excellent, though rare, specimens.”
