Rocks and minerals are important for learning about earth materials, structure, and systems. Studying these natural objects incorporates an understanding of earth science, chemistry, physics, and math. The learner can walk away with an understanding of crystal geometry, the ability to visualize 3-D objects, or knowing rates of crystallization.
Lunar plagioclase: This rock was collected from the surface of the Moon and brought back to Earth by Apollo 11 astronauts in July, 1969. It is a vesicular basalt made up of approximately 50% pyroxene, 30% plagioclase, and 20% other minerals. The rock has many .
Feldspars (K Al Si 3 O 8 – Na Al Si 3 O 8 – Ca Al 2 Si 2 O 8) are a group of rock-forming tectosilicate minerals that make up about 41% of the Earth's continental crust by weight.. Feldspars crystallize from magma as veins in both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock. Rock formed almost entirely of calcic plagioclase feldspar is known ...
Bowen's reaction series is able to explain why certain types of minerals tend to be found together while others are almost never associated with one another. He experimented in the early 1900s with powdered rock material that was heated until it melted and then allowed to cool to a target temperature whereupon he observed the types of minerals ...

The Rice Northwest Museum of Rocks and Minerals is the finest mineral museum in the Pacific Northwest and one of the best in the nation. The Rice Northwest Museum of Rocks and Minerals is located 25 minutes west on Highway 26 from downtown Portland, Oregon, near Hillsboro.
Plagioclase is a series of tectosilicate (framework silicate) minerals within the feldspar group. Rather than referring to a particular mineral with a specific chemical composition, plagioclase is a continuous solid solution series, more properly known as the plagioclase feldspar series (from the Ancient Greek for "oblique fracture", in reference to its two cleavage angles).

This is a list of minerals for which there are articles on Wikipedia.. Minerals are distinguished by various chemical and physical properties. Differences in chemical composition and crystal structure distinguish the various species.Within a mineral species there may be variation in physical properties or minor amounts of impurities that are recognized by mineralogists or wider society as a ...

Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy. The ...

Olivine.
Minerals are not equivalent to rocks. A rock is an aggregate of one or more minerals or mineraloids. Some rocks, such as limestone or quartzite, are composed primarily of one mineral – calcite or aragonite in the case of limestone, and quartz in the latter case.
The extrusive magma, because it is deep below the surface, cools very slowly producing very small mineral grains. Intrusive magma flows onto the Earth's surface and cools very slowly, allowing many small mineral grains to grow. Intrusive magma is cooler because it is well insulated by the surrounding rock.

The olivine Mineral Series Olivine is one of the most common minerals in the earth, and is a major rock forming mineral. Despite this, good specimens and large crystals are uncommon and sought after. Only few localities yield large examples of this mineral, although .
The Bowen reaction series is a description of how magma's minerals change as they cool. The petrologist Norman Bowen (1887–1956) carried out decades of melting experiments in the early 1900s in support of his theory of granite.
