Geologic map database to accompany geologic map of the State of Hawaii This digital publication contains all the geologic map information used to publish U.S. Geological Survey Geologic Investigations Map Series SIM-3143 (Sherrod and others, 2021). This geologic map shows the distribution and stratigraphic relation of volcanic, intrusive, and sedimentary units emplaced in the past 8 million years across the eight principal islands of the Hawaiian archipelago, State of Hawaii, U.S.A. This geologic map database is accompanied by a report, which includes the formatted geologic map and explanatory pamphlet, available at https://doi.org/10.3133/sim3143​. The authors ask that users of the geologic map database cite both the report and the database: Report: Sherrod, D.R., Sinton, J.M.,...

The San Juan Mountains are the largest erosional remnant of a composite volcanic field that covered much of the southern Rocky Mountains in middle Tertiary time. The San Juan field consists mainly of intermediate-composition lavas and breccias, erupted about 35-30 Ma from scattered central volcanoes (Conejos Formation) and overlain by voluminous ash-flow sheets erupted from caldera sources. In the central San Juan Mountains, eruption of at least 8,800 km3 of dacitic-rhyolitic magma as nine major ash...
