The small black crystals on the zircon 5b have been shown to be anatase based on work by Dr. Don Howard. The whitish plate on the the prism face of 5b may be xenotime.

The white coloration looks more like a surface feature to me rather than a plate attached to the zircon. A Mindat image of anatase on zircon leads me to the ID as well. I've added some zircon images to the Mindat gallery for Washington Pass.

Again, thanks for all the resposnes!

A few more Washington Pass images. The last one looks like siderite coated with malachite or perhaps a chlorite group mineral. Would welcome opinions on the first two. Thanks!
