The Mohs hardness scale classifies minerals by their resistance to scratching. Talc, at 1, can be scratched with a fingernail. Diamond, at 10, is the hardest known natural mineral. Between these extremes lie the feldspars, quartzes, and corundum that make up the bulk of the Earth's crust.

Cards & Panels

Mineral specimen cards with agate, geode, crystal, and malachite banding headers.

Chalcedony

Banded Agate

Concentric bands of microcrystalline quartz formed in volcanic vesicles over millions of years. Each band records a change in mineral-rich groundwater.

Formation

Amethyst Geode

Hollow rock cavities lined with inward-pointing crystals. The purple hue comes from trace iron impurities and natural irradiation.

Silicate

Rose Quartz

Translucent pink variety of quartz. The color originates from trace amounts of titanium, iron, or manganese in the crystal lattice.

Carbonate

Malachite

Banded copper carbonate mineral with distinctive green swirls. Forms in the oxidizing zone of copper ore deposits alongside azurite.

Horizontal Specimen Card

Featured Specimen

Labradorite Feldspar

A plagioclase feldspar displaying brilliant iridescent optical effects known as labradorescence. The schiller effect is caused by light refracting between sub-microscopic lamellae of different compositions.

07 / Indicators

Alerts & Notifications

Status messages styled as mineral indicators. Each alert type corresponds to a distinct mineral.

Amethyst / Informational
Specimen cataloged successfully. Crystal system and hardness data have been recorded in the field database.
Tourmaline / Success
XRD analysis complete. Mineral composition matches the expected feldspar group classification.
Citrine / Warning
Specimen fragile. Handle with care during transport. Avoid thermal shock as rapid temperature changes may cause fracturing.
Jasper / Danger
Radioactive specimen detected. Autunite sample exceeds safe handling threshold. Use lead-lined storage container.
Labradorite / Note
This specimen displays anomalous optical properties. Further spectroscopic analysis recommended before final classification.
08 / Traverse

Navigation

Tab navigation styled as geological survey waypoints.

12 / Axioms

Design Principles

The geological forces that shaped this design system.

Crystalline Structure

Every element follows a lattice of consistent spacing and alignment. Like atoms in a crystal, components snap to a defined grid with predictable relationships.

Stratified Depth

Information layers stack like geological strata. Background, surface, and elevated elements each occupy a distinct depth, creating clear visual hierarchy.

Mineral Palette

Colors derive from real mineral specimens. Each hue serves a semantic purpose rooted in its geological origin, from amethyst's authority to citrine's warmth.

Faceted Precision

Interactions reveal inner facets like cutting a gemstone. Hover states, focus rings, and transitions expose luminous surfaces beneath the exterior.

Deep Time

Animations move at geological pace. Transitions are deliberate and smooth, never jarring. Like mineral formation, the interface reveals itself gradually.

Natural Banding

Repeating patterns, like agate bands, provide rhythm without monotony. Each repetition carries subtle variation that rewards close inspection.
