altered conglomerate and a magnetic mafic dyke.

Think I found your previous answers....

More than likely this is what caused the Magnetics shown on the 3d model and hinted of IOCG ? Fair to say...

To Kiss butt some: Geology for minerals depends greatly on water and it temperature to concentrate and carry mineral atoms.
There by creating the formations that surround them and the minerals concentrations themselves.

Thanks again,, I grow weary of the "winkopedia" "DD"

KATX just needs a find and the chances are still there
As I read your posts you are realistic yet optimistic.
The fact that hey did find some REEs is good
Just need to get those numbers up some.

The described magnetic mafic dyke probably has no significance with respect to mineralization. Mafic desribes an igneous rock that has Mg and Fe (MAgnesium and ferRIC [or iron]), but it still dominantly silica (around 48-52 wt% SiO2).

Because of the iron content it can be magnetic. In fact, paleomagnetism uses the ancient alignment of Fe in mafic rocks (which comprise the oceanic crust) to figure out pole reversals and location of the plate through geologic histry. Once the mafic metls drop below the Curie point the iron atoms are not longer able to move around, so in any mafic rock it records the direction to the north pole at the TIME it cooled.

The conglomerant

Conglomerate is a sedimentary rock composed of large, rounded clasts, thus it is very porous and permeable. It is typically cemented together by precipitated calcite or silica. So the pore spaces are large. Aleration, in this case hematite, occurs during metamorphism, or in this case metasomatism, which basically describes hydrothermal fluids passing through the matrix (which is geo-talk for the cement) of the congomerate and replacing the original cement with hematite. I do not like to decribe it as Fe-ore, as that implies it is at a high enough grade to be profitable. We do not know this yet.

This is why is is also important to know the thickness of this conglomerate.

Another thing to consider is... did the hydrothermal fluids transport anything else of economic importance? And, if so, where would this "deposit" be located in relation to hole #1? Is it related to the REEs in Hole #2? This is what I find interesting...
