Orthopyroxene has much lower birefringence than clinopyroxene. In XPL, orthopyroxene ranges from first order grey to first order yellow. Clinopyroxene shows second order colors in the magenta and blue range.

What minerals are in lherzolite rock?
Olivine, Clinopyroxene, Orthopyroxene, Garnet and Spinel at great depth.
What is the difference between a tholeiitic basalt and an alkali basalt?
alkaline olivine basalt (thin section)-Silica under saturated. Interstices filled by alkali feldspar and felsphatoid. Olivine doesn't show reaction with orthopyroxene. It has olivine in the groundmassTholeiitic basalt (thin section ): Silica over-saturated. (>51%).Common Si-rich glassy mesostasis (Intersertal texture). Frequently contains pyroxene. Groundmass no olivine.Olivine shows reaction to orthopyroxene.
Explain why color is not a good test for distinguishing between pyrite and gold?
Since pyrite (a.k.a. fool's gold) and gold have the same color, it can be very difficult to distinguish between them. A very accurate way to distinguish them is by streaks.
How do you determine the rare earth element concentrations in a fulgurite?
To measure the abundances of rare earth elements in clinopyroxene and olivine of iron-silicon in a fulgurite, were made to determine the oxygen fugacity required.

What is moon made up of and what?
The crust of the Moon is composed mostly of oxygen, silicon, magnesium, iron, calcium, and aluminum. There are also trace elements like titanium, uranium, thorium, potassium and hydrogen. Scientists believe that the mantle of the Moon is largely composed of the minerals olivine, orthopyroxene and clinopyroxene. It's also believed to be more iron-rich than the Earth's mantle. Scientists think that the lunar core is made of metallic iron, with small amounts of sulfur and nickel.
