valkhormoonideks

Valkhormoonideks are a group of mineral-like crystalline compounds defined by lamellar silicate-phosphate sheets that display intrinsic luminescence. They typically form in hydrothermally altered basaltic rocks and are distinguished by their layered crystal structure and distinctive optical properties.

The name valkhormoonideks combines elements from the fictional Valkhorn region and a moon-related motif used in planetary geology studies. The term was introduced in the mid-22nd century by researchers at the Valkhorn Institute of Planetary Geology, following fieldwork in basaltic terrains analogous to lunar environments.

In terms of structure and composition, valkhormoonideks crystallize in the monoclinic system and feature a framework of interleaved silicate and phosphate layers. They commonly incorporate aluminum, iron, and magnesium, with trace chromium and rare earth elements detected in many samples. The minerals often exhibit a pale blue to green hue and luminescence under ultraviolet light.

Occurrence and formation processes place valkhormoonideks in hydrothermal alteration zones. They form at low to moderate temperatures within fracture networks of basaltic crusts and are frequently found alongside minerals such as chlorite, epidote, and iron oxides.

Physical properties include a Mohs hardness of about 5–6 and a density near 3.0–3.5 g/cm3. They range from transparent to translucent and may show varietal color differences related to trace element content. Their luminescent behavior and layered structure make them useful for mineral identification and for studying past hydrothermal activity in planetary crust analogs.
