Probably plag). Sheeted carbonate +/- qtz veinlets (usually few mms or less) consistently through section measuring approximate 40/180 to 44m. Porphyritic texture is common, with larger phenocrysts of what looks like plagioclase feldspar (pale, laths). Mineralization is pyrrhotite and chalcopyrite is localized blebs associated with the carbonate sheeted veinlets usually. Core is a bit blocky towards the top of the hole. There are isolated patches of chlorite alteration, usually around qtz/carb veinlets. Around 46m there is a few ms of section that looks almost faulted, but curved- looks a bit like what it would look like if you tried to fold a gabbro, with some elongation in the minerals and a curving fracture (starts and ends on the same side of the core) with lots of little slivers of fracture and finer material that is not quite gouge.

Not all of unit is magnetic, nothing with qtz veining is and it looks like most magnetite has been altered or replaced in other sections but it varies. The relationship between the pyrite/aspy mineralization in the iron formation and the presence of veins at low angles (main qtz-chlor vein at 168.03 really starts earlier as tiny veinlet down core axis) and low angle bed offsets is very obvious; mineralization radiating from paths of veins and shear/healed fracture lines. Pyrite approx. 5% aspy 0.5%, although as the massive qtz0chlor vein continues down section mineralization almost disappears towards the end of the section since it is no longer iron formation so much as it is just a vein, and mineralization, while found in very minor amounts in the veins, is really very much concentrated in the iron formation NEAR the veining. Minor carbonate present with qtz (or just really not fizzy) in fracture fills, very minor, most of this is first 50cm of section.

By volume most of it is probably oxide iron formation or WAS oxide iron formation before veining and alteration so called oxide iron formation / 2c. Alteration is usually nice grunerite alteration, with actinolite and chlorite. Carbonate veinlets and fracture infill are not uncommon. Mineralization is extremely variable and seems to be highly dependent on the level of veining and shearing/alteration as well as the presence of iron formation; it increases down section generally. Bedding is uniformly low angle, <25 deg TCA is common. Unaltered oxide iron formation is extremely magnetite rich, probably >50% magnetite. Pyrrhotite is the most common sulfide mineralization; pyrite is seen intergrown with it sometimes, and arsenopyrite is rather abundant locally (see mineralization intervals), with the most arsenopyrite often in very altered rock that is in very close proximity with more unaltered oxide iron formation and lots of veining both qtz-chlor and carbonate. Carbonate alteration is usually limited to fracture fill but sometimes it replaces beds within the iron formation in places where the beds in question intersect with a fracture filled with carbonate.

Actinolite.
