Exploring the Realms of Mineral Crystallography: Is Every Space Group Represented?

Introduction to space groups in crystallography Crystallography, the study of the internal structure and external form of crystals, is a fundamental discipline in the earth sciences. At the heart of crystallography is the concept of space groups, which describe the symmetry operations that leave a crystal structure unchanged. The question of whether each space group

Deciphering Crystal Habit in Weathered and Rounded Rocks: A Crystallographic Challenge

Determination of crystal habit in worn and rounded rocks When dealing with rocks that have been weathered and worn over time, determining the original crystal habit can be challenging. However, there are several techniques and approaches that can be used by the experienced crystallographer or geoscientist to infer the underlying crystal structure. One of the

The Enigmatic Beauty of Pallasite Meteorites: Unveiling the Iron-Nickel Phase

The Iron-Nickel Phase in Pallasite Meteorites: A Window into the Early History of the Earth Pallasite meteorites, named after the German naturalist Peter Simon Pallas, are a fascinating class of meteorites that provide valuable insights into the formation and evolution of our solar system. They are characterized by their unique composition, consisting of an iron-nickel

Unveiling the Mysteries of Enantiotropic and Monotropic Polymorphic Transitions in Earth Science Crystallography

Understanding Enantiotropic and Monotropic Polymorphic Transitions in Crystallography Crystallography, a branch of earth science, studies the structure, properties, and behavior of crystals. In this field, the study of polymorphism plays a crucial role. Polymorphism refers to the ability of a substance to exist in different crystal structures, called polymorphs, while maintaining the same chemical composition.

An overview of the oblique square prism crystal in crystallography Crystallography is a fascinating field that focuses on the study of crystals, their structures, and their properties. One intriguing crystal form that has received considerable attention in recent years is the oblique square prism crystal. This unique crystal structure has distinctive geometric features and plays

Cleavage vs. Fracture: Unveiling the Distinctions in Earth Science and Crystallography

Cleavage and fracture are two terms commonly used in crystallography and earth science to describe the way minerals break. While both processes involve the breaking of a mineral, there are distinct differences between cleavage and fracture. Understanding these differences is critical to identifying minerals and studying their properties. In this article, we will explore the

What does the unit cell of petitjeanite look like?

Introduction to Petitjeanite Petitjeanite is a rare mineral belonging to the apatite supergroup and named after the French mineralogist Pierre Petitjean. It was first discovered in the Democratic Republic of Congo and has since been found in a few other locations around the world. Petitjeanite is of great interest to crystallographers and geoscientists because of

Exploring the Analog Nature of Crystal Lattices: Unveiling Earthscience’s Intriguing Crystallographic Phenomena

Can crystal lattices be analogous? Crystallography, the study of crystal structures, has played a central role in understanding the properties and behavior of materials. The arrangement of atoms or molecules in a crystal lattice determines its unique physical and chemical properties. Traditionally, crystal lattices have been described using mathematical models and symmetry principles. However, recent

Crystal vs. Mineral: Understanding the Fundamental Differences in Earth Science and Crystallography

Crystallography and mineralogy are two branches of science that study the properties and characteristics of minerals and crystals. Although minerals and crystals may seem similar, they are different in many ways. In this article, we will discuss the differences between crystals and minerals. What is a mineral? A mineral is a naturally occurring inorganic solid
