There are cavities all over this specimen that are lined with superb, elongated, terminated thomsenolite crystals. Of course as is usually the case, the thomsenolite is white but has a light coating of iron oxide that give the specimen its classic look. Matrix appears to me massive thomsenolite with a few small siderite and sphalerite crystals embedded in it. As well, there are small cube-octahedral ralstonite crystals on the thomsenolite crystals, inside the vugs. We don't seem much of this material around any more!
