Figure 2 Schematic cross section of plains-style volcanism on the eastern Snake River Plain (ESRP) at three depth ranges and scales. Approximately 2 km to surface: illustration of the SRP surface to ~2 km depth showing laterally extensive, stacked lava flows, coalesced shield volcanoes, and Pleistocene-Holocene aeolian, fluvial, or lacustrine sedimentary interbeds overlying Miocene-Pliocene rhyolitic volcanics and Paleozoic sediments (modified from Greeley, 1977, and Hughes et al., 1999). Approximately 20-10 km depth: schematic illustration of the interpreted structure of the mafic sill complex from 20 to 10 km depth (modified from Shervais et al., 2006), including multiple stacked magma chambers in varying states of crystallization. Magma batches in the mid-crustal sill complex are chemically distinct and may stall and pond at different depths within the sill complex. Partial or residual melts in partly congealed basalt cumulates may interact with stored magmas prior to eruption or replenishment, resulting in cyclical fractional crystallization and assimilation (e.g., Potter et al., 2018). Sixty km to surface: cross section of the SRP region, showing seismic velocity characteristics of the crust and mafic sill complex (0-60 km depth) from Peng and Humphreys (1998).

Figure 4 (A) Schematic illustration of a typical (~6.2 m) inflated simple basalt flow as observed in the Kimama drill core, modified from Self et al. (1998). (B-Q): Photographs and depths of flow facies in the Kimama drill core. The depth of recovery in meters is given at the base of each photograph. Surface facies: glassy spatter (B), ropey pahoehoe (C), sediment-coated rubble (D), and flow and mold structures (E). Interior facies: segregation veins (F); massive flow interior, without vesicles (G); diktytaxitic texture (H); vesicle pipe (I); macrovesicle (~5 cm across) (J); elongate vesicles, a result of continued lava flow during cooling (K); remobilized spatter (also referred to as autolithic basalt) (L); calcite amygdule (M); smectite amygdule (N) (after Sant and Shervais, 2011); and hyaloclastite (O). Sediment interbed characteristics vary through the drill core: baked loess, fine-grained homogenous clay baked to terra cotta by the overlying lava flow (P); fluvial sediment interbed with normal grain-size gradation (detrital zircon samples were obtained from fluvial sediment layers at the base of the core for U-Pb analyses) (Q); and sediment-coated rubble (D).

Figure 5 Composite lithologic, natural gamma (cps), neutron (cps), paleomagnetic inclination, geochemistry (as Mg#) logs from the Kimama borehole. All data sets were used to categorize Kimama basalts into 78 flow groups (numbered) and 183 flows, boundaries indicated as white lines, consisting of 1-20 flow units. The 432 flow units are not shown. Four flow groups were not sampled in the drill core and are labeled 'NS.' Sediments are denoted by symbology and color to represent loess (orange), sandstone (red), sandy silt-siltstone (yellow), and hyaloclastite (purple). Geochemical and paleomagnetic inclination and polarity are represented using the same symbols to illustrate variations by flow group. (A) Composite logs from the surface to 1000 m depth. (B) Composite logs for 1000-1912 m depth. Correlation between the natural gamma ray logs and stratigraphic and geochemical data is apparent at 319 m depth, where an evolved, high K-Fe flow group (flow group 12) is imaged by an abrupt increase in the natural gamma signal.

Figure 6 Step age spectra and Ar/Ar isotope correlation diagrams from 40 Ar/ 39 Ar incremental heating experiments from Kimama basalt samples. Analyses were performed at Oregon State University. The upper figures are isotope correlation diagrams where the intercept of the regression represents the initial 40 Ar/ 36 Ar ratio. The lower figures show the step age spectrum; the thickness of the bar indicates the ±1 σ external error, and the horizontal lines adjacent to the plateau age indicate the steps used to calculate the plateau age. The filled green squares were used in a weighted linear regression to calculate an isochron age. MSWD-mean square of weighted deviates.

Figure 7 Accumulation rate estimated for Kimama drill core basalts from a linear fit model using Ar/Ar ages and paleomagnetic ages. The onset and termination of paleomagnetic chrons and subchrons are shown by the small red dots, with normal polarity intervals demonstrated by gray shading. Ar/Ar ages are indicated by blue circles; the Adelaide Butte age is published in Kuntz et al. (2018) The youngest U-Pb ages of detrital zircon grains in the lower fluvial successions are 5.8 ± 0.13 Ma at 1749 m, and 6.2 ± 0.1 Ma at 1844 m depth (Potter, 2014); these ages (pink circles) are overlain on the linear fit projection to demonstrate concurrence with the 320 m/m.y. accumulation rate and indicate a depositional period of <100,000 years (modified from Champion and Duncan, 2012).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
