Leon, hope it's of some help tho I realize that some nations censor this sort of thing

its usually cyclic depoition of mineralized water that flows through the already existing rock (its a post diagenetic feature).
Not much is known about em other than the lngth of the structures are usually at right angles to the earth. (Its a feature we can use to measure whether the rock body was still horizontal when the liesen formed. There are some liesegang rings that are metal carbonates so they do have minor ore values, but "bog ores" are more concentrated

well, I did a google research, and understand the formation and barely the chemistry, but what I really want to know (straight to the point) is, if that rings can be formed as a result of hidrotermal processes, I saw them on an outcrop andesitic dike, and at 200 meters depth on a drill core

Yes Leon, if ever, there's one for Man

is there any indiction of hydrothermal vents or pegmatites ?
usually there is some directionality associated with the structures, sorta like tree rings or "storm rollers"
