Minerals are links between Earth and human health

In fact, the earth's crust contains most of the mineral nutrients our body needs, and the chemical composition of a rock, such as granite, is strikingly similar to the composition of the human body. However, the minerals in granite usually are not in a form easily assimilated and dissolved in the body.

earth mineral composition Earth, Venus and Mars. To better understand Earth's composition and history, geologists sometimes compare our planet to other rocky planets in our solar system. Venus is a similar size to Earth and a little bit closer to the sun, while Mars is only about half the size of Earth.

earth mineral composition Chemical composition and crystal structure determine a mineral's properties, including density, shape, hardness, and color. Because each mineral forms under specific conditions, examining minerals helps scientists understand the history of earth and the other planets within our solar system.

Diatomaceous earth Wikipedia

The typical chemical composition of oven-dried diatomaceous earth is 80 to 90% silica, with 2 to 4% alumina (attributed mostly to clay minerals) and 0.5 to 2% iron oxide. Diatomaceous earth consists of fossilized remains of diatoms, a type of hard-shelled protists (chrysophytes).

The Earth's Core. The Earth's core is believed to consist of two regions. The inner core is solid, while the outer core is liquid. This phase difference probably reflects a difference in pressure and composition, rather than one of temperature.

Since the environment where most observable minerals occur is the Earth's crust, we must first explore the chemical composition of the Earth's crust. Composition of the Crust The Earth's crust is made up of about 95% igneous and metamorphic rocks, 4% shale, 0.75% sandstone, and 0.25% limestone.

Geology of the Moon Wikipedia

earth mineral composition Lunar rocks are in large part made of the same common rock forming minerals as found on Earth, such as olivine, pyroxene, and plagioclase feldspar (anorthosite). Plagioclase feldspar is mostly found in the lunar crust, whereas pyroxene and olivine are typically seen in the lunar mantle.

(left) Mineral composition is a key control of SSA, which describes how particles scatter and absorb energy. Iron-bearing minerals (represented here by hematite) are strong absorbers (SSA < 1.0) in the solar spectral region, while clay minerals (illite, kaolinite, and montmorillonite) are strong scatters (SSA ≈ 1.0). Particle radius is 0.5 µm.
