Im getting metoriot from everyone but beyond that i know no more. Im waiting for the local gem and mineral show to send it around to get a real ID but if anyone can give me some infor that would be great. very stone magnetism. Cube medals in the stone/ or fusion crust martix with orange red crystal clusters. Heavy Black. Found at local flea market with little to no ifro other than the man told me Somme told him its from Brazil 464.JPG. But thats iup in the air. so here are some shots please help me thanks!575.JPG

Hey I found this rock on lawrencetown beach Nova Scotia. Haven't been able to figure out what it is... Wondering if someone could help me find out! image.jpg
 

Any experts?

Very heavy (over 8 lbs); does not attract a magnet; white quartz-like areas scratch glass; black and red appear to be hematite according to streak test. The hematite veins seem unusual and the quartz seems to have been crushed (brecciated?). I'm wondering how something like this could have formed. There was some volcanic activity nearby. (Watchung Mountains in New Jersey).

Hey Carrol,

Looks like an old chunk of iron that has been sitting in the elements for a long time.

Easy to tell if its a meteorite, just cut it in half and put some acid on the fresh cut so you can see the grain structure. Lots of websites to help ID a meteorite. I am afraid I am not THAT knowledgeable about meteorites.

Thanks for trying!! Its already broke in 3 pieces, this being the largest.
I bought storage lockers for over 10 yrs (till the tv shows came on),
& this was in a box marked meteorite.

The largest stone...Is this a pudding stone?View attachment 1188647

It looks like a breccia to me. It looks like some granite that is fused together with ash/tuff/tephra. If you note that the red granite parts or clasts are more angular you will see how that differs from a puddingstone. A puddingstone is a conglomerate and they tend to have round clasts fused together in some sort of matrix by sedimentary processes. The puddingstones around here have red jasper, chert, hematite, banded iron pebbles that are held together in a matrix of quartzite. This gives the appearance of round red/brown things in a tan background much like raisins would look like in pudding. Here is an example of what they look like around here:

I agree it is brecciated. It seems like it was part of a larger rock body at one time but broke off and has been weathered(rounded). It likely has traveled a fair distances from the original location in the bedrock where it was formed. Wherever it came from I suspect it was part of a hydro-thermal system in a shear zone and the iron staining could be weathered pyrite/pyrrhotite or even some iron carbonates like siderite. The brown/black staining could be some manganese oxides.

In my opinion, Gollum is correct to break it open or cut it open to see what a non weathered face would look like. Also from what I can see it is limonite(bog iron ore) and not a meteorite. It may have been hematite or magnetite at one point but now it is just essentially rust.

thanks for the info!
 

Hey Carrol.
You don't want to cut it in half, only grind a small window. The larger the specimen the more valuable. BTW if it's iron the sparks from grinding should resemble a 4th of July sparkler.
One type of meteorites are iron and nickel usually about 90% iron if it is a siderite, basic stainless steel if some carbon is lurking around. Meteorites are always alloyed with nickel so a test for nickel would tell a lot.
