Predictive Mineralogy

Possible unrecorded species at Island County, Washington, USA

This table is based on statistical analysis of other localities containing similar species to the ones found at this locality.

Possible missing speciesFormulaMatch %Due to recorded presence of
PyriteFeS278.23%Calcite (51.16 %), Strontianite (55.45 %)
BaryteBaSO441.18%Strontianite (51.49 %)

Key: Mineral matches key element mineralogy of deposit Key element(s) in mineral not listed for deposit (-20% score)


Predicting paragenetic modes of deposit

Green indicates almost certain match based on minerals unique to a certain deposit type. Yellow indicates a possibly poor match, but should not be entirely discounted. Scores > 100 indicate strong confidence.

Paragenetic ModeScore
23 : Subaerial aqueous alteration by non-redox-sensitive fluids (see also #47)50
40 : Regional metamorphism (greenschist, amphibolite, granulite facies)49
36 : Carbonatites, kimberlites, and related igneous rocks49
47c : Low-𝑇 subaerial oxidative hydration, weathering (see also #16 and #23) - [Carbonates, phosphates, borates, nitrates]48
6 : Secondary asteroid phases2
9 : Lava/xenolith minerals (hornfels, sanidinite facies)2
10 : Basalt-hosted zeolite minerals2
49 : Oxic cellular biomineralization (see also #44)2
35 : Ultra-alkali and agpaitic igneous rocks2
14 : Hot springs, geysers, and other subaerial geothermal minerals2
