hypogene การใช้

Although the features of turquoise occurrences are consistent with a secondary or hypogene origin.
The " hypogene " hypothesis holds that the aqueous solutions originate at significant depth, from hydrothermal processes.
Covellite formed as clusters in these supergene enrichment zone oxidizes and redeposits covellite on hypogene sulfides ( pyrite and chalcopyrite ).
These secondary sulfides arise from the leaching of the overlying ore and its re-deposition on and replacement of the deeper primary ( hypogene ) sulfides.
This hypogene process is applicable to the original copper sulfide deposition; however, it is difficult to account for the many features of turquoise occurrences by a hypogene process.
