It's based on a granite pattern, with a high poly_wave value to make the 
veins thinner. Here's the code for the white marble (black's basically the 
inverse of this):

pigment {
 pigment_pattern { granite colour_map { [0 rgb 1][1 rgb 0] } }
 poly_wave 8
 scale <1,2,2> rotate -60*y
 colour_map { [0 rgb .5][1 rgb 0] }
}
