pneumatolytic การใช้

• This enabled the pneumatolytic and hydrothermal solutions to deposit their dissolved mineral contents.
• Pseudobrookite forms as pneumatolytic deposition and alteration within titanium-rich volcanic rocks such as andesite, rhyolite or basalt.
• It is formed by crystallizing under low pressure and high temperature from a pneumatolytic phase along fractures or within near-surface miarolitic cavities of the rhyolite.
