Naming logic
Texture and material qualifiers
These terms modify a root name and should not be treated as compositions by themselves.

Igneous classification integrity
Occurrence–texture–composition matrix
A field-oriented overview based on occurrence, texture, and broad composition. Texture terms act as qualifiers; modal mineralogy or chemistry is required for formal classification.
Measured texture
Quantitative grain-size translator
Enter a representative matrix or groundmass grain diameter. The largest phenocryst should be recorded separately.
Silica-undersaturated path
Alkaline and feldspathoid-bearing rocks
These families do not fit a simple light-to-dark felsic–mafic row. Formal names often require modal or chemical data.
Separate classification first
Special igneous families
Pipe rocks, carbonatites, lamprophyres, and related families require specialized mineralogical or chemical criteria.
Fragment-size path
Pyroclastic size classifier
Pyroclastic names depend strongly on fragment size and component proportions, not only magma composition.
Whole-rock chemistry
TAS volcanic classifier
Enter volatile-free, normalized SiO₂ and total alkalis (Na₂O + K₂O). This field-oriented implementation provides a classification aid and records the naming limits.
Advanced classifier
QAPF-style plutonic classifier
Enter modal percentages for quartz (Q), alkali feldspar (A), plagioclase (P), and feldspathoids (F). Values are normalized automatically.
Classification provenance and limitations
Sedimentary origin and texture chart
Clastic grain size, depositional texture, composition, acid reaction, and fossils are treated independently.
Metamorphic fabric, grade, and facies
The pelitic sequence is generalized. Pressure, temperature, bulk composition, fluids, and reaction progress control actual assemblages.

Explore plausible transformations. These are pathways, not claims that every rock follows a single closed cycle.

Field-test protocols
These procedures improve observation quality. They do not replace petrographic or laboratory confirmation.
Integration readiness
Rock data contract
Inspect the exact record sent to Mineral ID, the periodic table, and the GeoSuite fusion workspace. Oxide values are clearly marked as class-level proxies unless actual analytical data are supplied.

Field names are evidence-limited. QAPF-style results require reliable modal mineralogy; alkaline, feldspathoid-bearing, pyroclastic, and special igneous rocks often require petrography or whole-rock chemistry.
