Symplectites form from the breakdown of unstable phases, and may be composed of minerals, ceramics, or metals. Fundamentally, their formation is the result of slow grain-boundary diffusion relative to interface propagation rate.

thumb|A lithophysa from France thumb|A collection of lithophysae "thundereggs" A lithophysa (plural lithophysae, from Greek lithos "stone" + phusa "bubble") is a felsic volcanic rock with a spherulitic structure and interior cavity with concentric chambers. Its outer shape is spherical or lenticular. They vary in size from very small up to twelve feet in diameter depending on the age of the magma chamber. These rocks are usually found within obsidian or rhyolite lava flows. Lavas low in feldspar minerals may produce a version known as snowflake obsidian.

Iberulites are a particular type of microspherulites (Fig. 1) that develop in the atmosphere (troposphere), finally falling to the Earth's surface. The name comes from the Iberian Peninsula where they were discovered.

Micromount is term used by mineral collectors and amateur geologists to describe mineral specimens that are best appreciated using an optical aid, commonly a hand-lens or a binocular microscope. The magnification employed ranges from 10 to 40 times.
