Euhedral and anhedral are terms used to describe opposite properties in the formation of crystals. Euhedral (also known as idiomorphic or automorphic) crystals are those that are well-formed, …

Crystals are said to be euhedral (synonyms: idiomorphic, automorphic) when they are bounded by their characteristic crystal faces, in other words when they show their crystal habit.

Hence, it is also important to describe the quality of the shape of a mineral specimen: Euhedral: a crystal that is completely bounded by its characteristic faces, well-formed. Synonymous terms: …

…faces can be described as euhedral or panidiomorphic (fully crystal-faced), subhedral or hypidiomorphic (partly faced), or anhedral or allotriomorphic (no external crystal faces). Quite …

“Crystal form” is a concept similar to “crystal habit”. A crystal form is a solid crystalline object that is bounded by a set of flat faces that are related to one another by symmetry. Euhedral …

2022年12月16日 · We describe crystals, such as the well-formed garnet crystal with well-developed faces, as being euhedral. On the other hand, petrologists and mineralogists may …

The drawing shows separate atoms coming together to produce a cubic crystal. In this example, the crystal is euhedral with six identical faces. But, even if it did not develop crystal faces, the …

An euhedral crystal is defined as a crystal that has well-defined, sharp, and distinct crystal faces due to uninterrupted growth without external interference, commonly seen in diamond …

2016年3月11日 · Euhedral crystals are those with obvious, well-formed flat faces. Anhedral crystals do not, usually because the crystal is one grain in a polycrystalline solid. The flat faces …

Euhedral (diamond shaped cross section), white lawsonite crystals grew in this glaucophane schist from northwestern Syros, Greece. Although the lawsonite has been replaced by a very …
