Rock with green melt??
- Thread starter rockpassion
- Start date
Very interesting ... I'd be of no use in ID'ing, but: Could you give the (general) location & type of terrain where you found this ... general knowledge of the geology of the area would be very helpful to a knowledgeable person who could help ... really neat rock, & am curious also ...

Try Googling for 'brecciated green jasper'. I think you'll find rocks with similar appearance.

x marks the spot and most of the rocks there are from glacial deposits.

yes it could be but in my rock the fragments are not so sharp defined and not really angular like jasper breccia. so don't even no if it is technically a breccia. P.S. we also don't have green brecciated jasper in the netherlands i believe. have never found any

Many brecciated jaspers have undergone a degree of metamorphism subsequent to initial fracturing. That typically creates mottled colours and 'blurring' of the brecciated texture.

I have a lot of green glassy rock that is local metallurgical slag used for fill and road work. Looks just like your rock.

Waiting for an Expert;
I'm not a expert. I was once told, "An expert is a has-been drip under pressure!"
In 25 words or less, rocks come from all walks of life. Witwatersrand has/is/was a metamorphic GOLD Placer.
Are we having FUN yet?

I can assure you 100% I never suggested it is a slag.
Without context of "where" is was found and association with other rocks, it is difficult to say what the rock is.
Rocks associated with volcanic rocks often share a glassy volcanic surface texture. Rocks ejected from a volcanic source have a glassy surface as they exit a volcanic vent for example and as they cool during flight through the air become semi solid and upon landing may crack slightly. There are too many possibilities without context.
Thanks for sharing an interesting rock!

Looking at the image "X marks the spot". the spot appears to be a sea wall or wall that is used to shore up and reinforce the shore line. With what appears to be a railroad to the left, it is likely transported from a mine or quarry that is used for land fill along shore lines. Dense (heavy) rocks are excellent for this purpose.!

We have Context;

The true location of origin remains unknown. A call or email to the engineers of the wall (not the Waal) may be able to provide details on the origin. Engineers specify the materials and could give exact details!
I love this place!
