COLerdem

Codeldem is a high-temperature phase of the iron oxide mineral garnierite, an hydrous nickel silicate. This phase is characterized by a different crystal structure compared to the low-temperature form. Codeldem crystals are typically formed through high-pressure and high-temperature experiments, or as a result of rapidly cooling iron-rich magmas.

The Codeldem phase has been the subject of scientific study due to its unique properties, which are also observed in naturally occurring garnierite. Research into this material has led to a greater understanding of the complex relationships between iron, nickel, and oxygen in nickel silicate minerals. These studies have also shed light on the processes that govern the formation of nickel-bearing minerals in Earth's crust.

Codeldem crystals exhibit distinct optical and chemical properties, which are exploited in various analytical techniques. For example, transmission electron microscopy (TEM) is used to examine the crystal structure of codeldem. Additionally, codeldem is studied using scanning electron microscopy (SEM), which can provide information about the crystal composition and topography. X-ray diffraction (XRD) is also employed to determine the crystal structure and identify codeldem in rocks and minerals.

The study of Codeldem contributes to the broader field of mineral science and the understanding of nickel silicate minerals. Continued research into this high-temperature phase of garnierite will provide insights into geological processes and may have implications for the extraction and understanding of nickel-rich resources. As new analytical techniques are developed and new samples are studied, scientists continue to refine their understanding of the Codeldem phase and its place within the broader field of geology.
