fluidal การใช้

• The original porphyritic, fluidal, vesicular or fragmental structures of the igneous rock are clearly visible in the less advanced stages of hornfelsing, but become less evident as the alteration progresses.
• As crystallization was going on while the mass was still creeping forward under the surface of the Earth, the latest formed minerals ( in the ground-mass ) are commonly arranged in subparallel winding lines that follow the direction of movement ( fluxion or fluidal structure )  and larger early minerals that previously crystallized may show the same arrangement.
