Sentence examples for eruption age from inspiring English sources

Desert pavements from the Bishop Tuff yield exposure ages that are ∼ 60% of the tuff's 40Ar/39Ar eruption age.

In water deer, Hydropotes inermis, the eruption age of mandibular molars has been described in two studies, but the ages were inconsistent with each other.

Relations between temperature and CO2 consumption rate for active volcanic fields (AVFs) are complicated by other factors such as eruption age, hydrothermal activity, and hydrological complexities.

In addition, we successfully employed zircon geochemistry (trace elements, oxygen isotopes) as an alteration-resistant indicator to correlate rhyodacitic to rhyolitic ignimbrites whose eruption age differences are too brief to be resolved by 40Ar/39Ar geochronology.

Using the density of the Bishop Tuff and a published 40Ar/39Ar eruption age for the tuff (760 ± 2 ka), the absolute amount of erosion since eruption has been quantified.

In this study, we aimed to confirm the eruption age of mandibular posterior teeth for the accurate age determination of water deer and to evaluate the efficacy of maxillary posterior teeth for the age determination of deer.

Because uncertainties in eruption ages and volumes increase with age of the eruptive products, it is difficult to compare the eruption rates of poorly preserved, older eruptions to recent eruptions occurring over a similar time interval.

Thus, desert pavements are more suitable for determining the minimum eruption ages of yet-undated welded tuffs than bedrock exposures.

October 2018: Our new paper, published in Geochemical Perspective Letters, demonstrates a new, less sobujective, method of calculating volcanic eruption ages from high-precision U-Pb zircon geochronologic data.

The eruption ages of several widespread tephras have been estimated using magneto-, bio-, and isotopic stratigraphy.

In contrast, the eruption ages of the Late Pleistocene to the Holocene marine tephras are typically determined with the radiocarbon dating of associated planktonic foraminifera, which obtain carbon from the surface waters.
