(There’s actually very little about Kilbourne Hole in any of these links, but your friendly author’s fellow space exploration nerds enthusiasts know how it is–you find one thing, and then other things, and then you want to share all the things with all the people. an excellent overview of the geologic setting and features of Kilbourne Hole. solution where the iron and magnesium atoms can be substituted for each other without significantly changing the crystal The New Mexico Bureau of Geology and and Mineral Resources has published an excellent overview of the geologic setting and features of Kilbourne Hole. These days, NASA and others are using Kilbourne Hole to test equipment and methods which might someday be used on other solar system bodies. The Footsteps of Apollo Astronauts, another blog post from NASA Earth Observatory, features geologist and Apollo 17 astronaut Jack Schmitt. As mentioned previously, there is a size mismatch of only about 7% between Mg2+ and Fe2+, Space exploration enthusiasts should absolutely scroll to the Bonus Content section at the bottom of this page to learn about NASA using Kilbourne Hole as an Apollo training site and modern equipment testing site. Mg. Fayalite (Fe2SiO4) and forsterite (Mg2SiO4) form a substitutional solid NASA has brief but full descriptions of 12002 here and 12005 here. If you need end member-specific information, please see the forsterite and fayalite pages. As of 2020, Schmitt remains the only professional scientist to have set foot on another solar system body.

Magnetite with fayalite Scanning electron micrograph of olivine. two types of octahedral site (M1 and M2). The compositional range between end-member minerals that exhibit complete solid solution is known as a solid solution series. The lunar samples were imaged by, and are used with the permission of, Paul Karabinos. Xenobombs are pretty great. This is known as complete solid solution.

The structure consists of isolated SiO44- tetrahedra, which are held together by M cations occupying Olivine has an orthorhombic structure. If you’d like to learn a little more about them, scroll down to the Bonus Content section at the bottom of this page. close packing were ideal, the M1 and M2 sites would be regular octahedra, and identical in size, but since the packing is Alternatively, the structure can be described as an approximately hexagonal close-packed array of oxygen anions, with M If you need end member-specific information, please see the forsterite and fayalite pages. Olivine in another xenobomb His 330-page Science Training History of the Apollo Astronauts is available online, and talks about their training at Kilbourne Hole in some detail. Olivine in gabbro, plane polars Click here for crossed polars: https://youtu.be/3AjgwewWfsk Magnifi…, Barred olivine chondrule from the Cole Creek meteorite in cross polarized light. Callan Bentley is (rightly) rather taken with xenobombs, and has published three blog posts about them. Rotating VR model of the olivine structure: oxygen atoms are shown in red, silicon atoms in blue, M cations occupying M1 sites in yellow, and M cations occupying M2 sites in purple, Creative Commons Attribution-NonCommercial-ShareAlike 2.0 UK: Kilbourne Hole, where both of the xenobombs featured here were collected, is also pretty great. structure. There’s a picture of Troctolite 76535, at least, and it’s studded with olivine, so the argument can be made that it still belongs on this page.
