I was doing some field searching and after some heavy rains this area became more heavily washed out revealing a basin of sorts. Does this look like an ocean floor remains, volcanic flow, or some type of slag dump pit? The things ive found in and around it are very different. I'm not sure what slag really is but someone please tell me if this is a type of slag. Most objects in this basin are very light weight, vesicular, and remind me almost of a coal or some kind of carbon on some inside parts. There are a couple of layers, one layer is made up of almost entirely smaller than golfball sized fragments like a tephra. The other layer almost reminds of of compacted sand or a heavily weathered member closely related to anorthosite or andesite. The one object plucked straight out from one of the layers is dense, still vesicular, and instead of being slightly magnetic at spots like the rest of the material, this is truly magnetic. There is also a very heavy stench of sulfur.
My wildest guess would be some sort of layers that underwent some type of acidic leaching. Im just a novice though.
Basin washout:
Materials found on top of the washout, and one heavy magnetic object that was plucked from a differant layer than the rest:
Magnetic heavy:
Rest are lightweight and only slightly magnetic at spots, one seems to have a piece of wood intergrained in it and almost reminds me of a volcanic bomb, others seem like a tephra??:
and here is a video if it helps
edit: I suppose the bomb is heavy but the many smaller fragments all around (which may have came from bombs) are air light

Does not appear to be a slag pit that got uncovered. Smokey's thought may help~ general location? I'm stuck between a hotspring and a volcano...
