B Type Veins in Porphyry Copper Systems
Тәжірибелік нұсқаулар және стиль
B Type veins are a unique indicator of the magmatic hydrothermal transition environment where porphyry type copper, gold and molybdenum deposit form. Learning to identify them is a really useful tool in the kit for mineral exploration geologists.
They were first identified by Gustafson and Hunt in the El Salvador porphyry copper deposit in Chile:
Gustafson, L.B., and Hunt, J.P., 1975, The porphyry copper deposit at El
Salvador, Chile: Economic Geology, v. 73, p. 600-607.

D type veins are a much more difficult issue because the textures and mineralogy are similar in a wide variety of deposit styles. If you already know you are in a porphyry system, life is a bit easier, but still plenty of room for argument!

Is there a Sodomitic zone, too? I.e. with an enhanced sodium content?
@GeologyUpSkill
Жыл бұрын
In this case yes. Actually many porphyry style hydrothermal systems develop a core of sodic rather than potassic alteration (like this one) but they all get lumped into potassic because it is nearly impossible to distinguish alteration k-feldspar from alteration albite reliably in the field.
Hay bud if you get satellite map of Australia and then turn map upside down then look far right near coastal township of Karratha western Australia and then look closely and you'll see two huge eyes on head with a bird beak type snout with wings spanning across continent and tail feathers ending up near Adelaide South Australia. If you zoom down near Queensland northern territory border you'll see feather striations on the landscape. Mayby Uluru Ayers Rock could have been it's heart. Amazing incredible a winged serpent dragon Phoenix creature spanning two thirds of the continent. This only could have been discussing due to modern satellite technology.

B veins are common in porphyry environments but not unique to mineralized ones. The exploration world needs to spend some time looking at what the geological norm is !

Yes. B veins only tell you that there is an intrusive issuing fluid. If that fluid is just bath water (the most common situation) you get nothing but quartz and a bunch of altered rock. Mineralization is a whole nuther story!

The observations are great, but so called "B veins" are a made up term that essentially describes a relative timing or paragenesis/mineralogy, so something to be AVOIDED! A good description and measurement of the vein orientation, mineralogy, relative timing and mode of opening (extensional, extensional-shear, shear, unknown) is always preferable, rather than use outdated (1975) terminology. But again, some great observation and description skills here! :)

Thanks Agatha. I did note the origins of the name in the video and, like most pigeonholes in geology, it has become enlarged and distorted over time, but for me, it's just a convenient name for the collection of characteristics that I described in the video. I have found that collection to be a very useful exploration guide when I'm looking for porphyry type systems. There are similar arguments to be made about the "porphyry" system label, but again, it's just a convenient name that works.
