Not a great picture but black minerals from Missouri are a big clue.

It looks like stream eroded Galena. The state mineral of Missouri is Galena (the ore of lead). The black cubes are probably Sphalerite (zinc ore). The Sphalerite is harder than the Galena so it doesn't erode as fast. Galena and Sphalerite are frequently found together..

The area around Fredericktown is well known for it's lead and zinc mines.

Most of Missouri is composed of sandstone and limestone. There are some small granite exposures in southeast Missouri and some even smaller Rhyolite dikes in the same area.

Schists are rare in Missouri and even rarer are mica and garnets. Although we only have a blurry picture to go by, the odds of mica schist much less mica/garnet schist being found in Missouri are vanishingly small. The area where this was found is historically known for commercial mining of lead (Galena) and zinc (Sphalerite).

Assuming this is a rock or mineral and not a piece of charcoal or a joke occams razor points to lead/zinc minerals. The simplest and most obvious answer is most often the right answer. If we had more information (hardness, specific gravity, streak) we could actually probably nail this down. Without that information it's just a picture.

Where exactly did you find this? in a natural type setting? I know that Mica Schist rocks that look like that are used for decorative purposes (landscape) and is shipped all over for that purpose. A landscape supply place has literally tons of it nearby me.
