Shaun did not misspell a single word from the opening round up to round 12, when he approached the mic and correctly spelled 'xenolith', a word of Greek origin which means "a rock trapped inside another rock", to cinch his win.

Located on the eastern edge of the Front Range of the Southern Rocky Mountains, the Kelsey Lake kimberlites were discovered in 1986-87 following a period of relatively intense exploration activity in the area after an earlier accidental find of diamond in a peridotite xenolith by a CSU graduate.

[55] suggested that the ascent of the xenoliths to the surface took place in a very short time, for example, less than nine days (assuming a diameter of 45 cm, corresponding to the largest xenolith size, a density of 3.3 g/[cm.sup.3], and an origin of the hosting liquids from depth ~70-75 km, i.e., Thoundary between garnet and spinel peridotite).
Objectives of this study include: 1) determining mineral composition of olivine, clinopyroxene, and orthopyroxene in the xenoliths; 2) examining individual chemical zoning characteristics or orthopyroxene, clinopyroxene, and olivine; 3) comparing mineral chemistry and zoning differences between xenoliths from different eruption styles; and 4) use xenolith compositions to determine lithospheric mantle pressure and temperature.
