Regional Geology

This information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys. This data will improve over time as more accurate maps and data sets are added.

Tertiary - Cretaceous2.588 - 145 MaBoulder batholith and broadly related stocks

Major:: {quartz monzonite},Minor:: {diorite},Incidental:: {aplite}

Boulder batholith and broadly related stocks: mainly quartz monzonite, but includes diorite, aplite, and other rocks. The distinctions between masses relative to the Boulder batholith and those mapped as of other ages are locally arbitrary and tentative.

As stated in map explanation, this map unit contains a number of broadly related stocks. Many of the stocks are named (too many to note). Most of the rocks represented by this unit are Cretaceous in age and hypabyssal, but a large number of smaller cross-cutting Tertiary stocks and intrusives are lumped into the unit as shown on the state map. Also, note that the large TKb body in the SW-most part of the state map actually consists of Proterozoic rocks.

Late Cretaceous66 - 100.5 MaLate Cretaceous plutonic: undivided granitic rocks

Plutonic: undivided granitic rocks

Late Cretaceous66 - 100.5 MaBoulder batholith, Butte Quartz Monzonite

Major:: {quartz monzonite, monzogranite-to-granodiorite}

Cretaceous66 - 145 MaCretaceous plutonic rocks

Plutonic rocks

Boulder Batholith

Deep-seated to high-level intrusions are included. Many charnockites, anorthosites, and large ophiolites, classified as plutons, are distinguished in the database using the SIGNIF item. Ophiolites were classified as plutons, even where remnants may be extrusive and/or sedimentary.
