Hi Jack,
In Arkansas there are areas where black coatings and fillings in rock fractures are manganese oxides. Red is common to be iron, but iron usually only stains a rock. If you send me some of the rock pebbles, I will look at them and if required make a few tests to identify your mineral. Are they from the area where the bauxite deposits were mined. They could be lateritic iron or aluminum coatings. mike
