What type of stone is this??
|

| Cranko |
sorry cant help there James, does it split or crumble when hit 
|

Does it make sparks against steel? Looks kinda flint-like to me... | ||
| James |
I'll check tomorrow 
|

That's what I thought Mr. B. I see enough of flint in this village its almost sickening 
|
||
| Chris |
Yep, looks like a flint.
Do the steel test. Not sure what it is if it isn't that. Certainly looks igneous. |
||
| James |
There are massive bits down that gun turret hole thing. One thing, if it's flint... it would have been chucked down there on purpose (to fill the hole in) - why would they have had random massive pieces of flint in a factory like that? | ||
| James |
BTW Chris, flint is a sedimentary not igneous

It looks like a byproduct of smelting that is called Slag over here, I think it the UK the word has a different meaning so lets not go there.
In an Iron works that would be a material that they would have in excess and would use it as an aggregate to fill holes in the ground with. Maybe someone can tell me what it is called in the UK, but like I said in the US it is called Slag. I have also seen it mixed with concrete not only as aggregate, but to assist with people gaining traction on concrete sidewalks that get wet or icy. |

| James |
It's called slag over here too mate
I'll post a pic up of the stuff I think is slag tomorrow! |
||
| Dave B |
I always pictured slag as kind of porous and crumbly, not at all like the stuff that James is asking about... | ||

RocDoc's away, but he'll know - ask him when he comes back next week. | ||
| Cranko |
RocDoc abit of an xpert on slags is he

Wikipedia to the rescue!

Blow me! Geology is a mystery! I think of sedimentary as being like sandstone and chalk Metamorphic as being like slate Igneous as being like granite. I'm sticking to concrete from now on. |
||
| James |
LOL!!
I want RocDoc back :rofl Ooo how about StillDrillin?? |
||
| Mister Occlusion |
I'd go with some sort of man made melt too.. unless it's a lump of anthracite coal (dunno if you have that over there).
unlikely they'd use coal for backfill, though. |

Sedimentry is rock that forms from several layers of sediment thats why theres fossils in it
Igneous rock is when lava cools down to form rocks Metamorphic rock is igneous rock is comperessed under immense heat and pressure
|
||
| Chris |
Yeah, I know that. That is why I thought flint was igneous. Flint doesn't look like layers of sediment to me.
|
||
| Stilldrillin |
You leave Stilldrillin alone! He dunt know either. 
Could put you a hole through it, if you want.
|
||
| James |
LMAO! !
|
||
| johnreid |
I believe Granite is Metamorphic, it was Limestone at one time, am I wrong?
That still looks like Slag to me and it is a logical find for that location too. |
||
| James |
I'm sure it ain't, I got a big lump of slag and it looks totally different. | ||
| Chris |
granite noun a hard coarse-grained igneous rock, consisting mainly of quartz, feldspar and mica, widely used in the construction of buildings and roads. granitic adj. ETYMOLOGY: 17c: from Italian granito, literally 'grained'. |
||
| steamyjim |
I thought flint was igneous aswell

Flint is a nodular accretion(!) of amorphous silica which forms in chalk (a very well known sedimentary rock). The last I heard it was believed to derive from the silica spicules found in sponges. Chalk itself is formed from the shells of tiny marine creatures (billions of them) so it makes sense. | ||

The plot thickens
