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.

    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.

    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timing and mode of opening (extensional, extensional-shear, shear, unknown) is always preferable, rather than use outdated (1975) terminology.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.
