Possible Iron Source?

Recommended Posts

Hey Everyone,

I've just started to get into this kind of stuff and learned that you can find iron sources all around depending where you live. From what I've learned is you might be able to spot a source by what looks like oil on top of water.

Where I live I can see some runoff water that looks just like the images I've seen online. In my images the white reflective is the oil substance. When it dries up it leaves what looks like a rust color on the ground (could be just dirt?).

If possible, would anybody be able to confirm if I live near one of these sources?

It only takes a couple of percentage points of Fe to give a real good "iron stain" to things so you are hoping to get limonite to smelt rather than just iron stained sandstone or other.  Central Florida; ouch.  We used to live where you could drag a magnet through creeks and get iron sand, (magnetite), which makes a great smelting ore.  It comes from igneous and metamorphic rocks and the ice age did a great preprocessing of those to free up the magnetite grains.  If bog iron ore is supposed to be around there; find out where!

We actually have an iron ore source in town out here, Goethite; also manganese  which helps a lot more with coke smelted iron ores.

OCCURRENCE: Bishop and Dee (1961) reported that a deposit of limonite exists near Chiefland, Levy County. They also reported a deposit of yellow ochre in Flagler County. Limonite gives rust-colored stains to soils, limestones, and clays; in larger amounts it acts to cement sand grains and clay particles into hardpans or concretionary forms.

It might make sense to evaluate my cemented layer that is around 4-5 feet deep. It is a little yellowish. I had never given any consideration to it perhaps being iron containing. I'm certain that it has too much silicon in all of the sand that would accompany it though. I would have to add crushed shells to keep from losing too much iron to iron silicates. I would have to relearn my mass and energy transport material so that I can just calculate the right quantities if it turns out to be useful ore. 

As for the old sites - I am sure that records detailing the 1860s production can be had. That area is not too far north of me.

It takes only a small amount of oxides to stain a large amount of rock.  The old copper miners/prospectors said, "A penny's worth of copper can stain a ton of rock."  Anything which is going to have a usable amount of iron is going to feel heavy in your hand, heavier than a normal rock of the same size.  Limonite (yellow) or hematite (red brown) staining can be a good first indicator but there has to be more concentration to be even a poor ore.

As Thomas said, magnetite is a good ore but I don't think you'll find much in Florida which is all sedimentary rocks and the glaciers never got that for south.
