Sentences with phrase «1c age model»

Not exact matches

The revised age — depth model reveals that the published age estimates based on some previously identified paleomagnetic events and optically stimulated luminescence dates from MAL05 - 1C are inaccurate for sediment older than ∼ 50 ka.

A revised Bayesian age - depth model for the upper 30 m of MAL05 - 1C based on 15 radiocarbon dates (24) and the age of the YTT: 75 ± 0.9 ka B.P. (4).

Here we take the age of 75.0 ± 0.9 ka B.P., which was calculated using the currently best constrained 40Ar / 39Ar optimization model (4, 31) as the most robust age for the YTT, and import it into a revised Bayesian age model for the Lake Malawi central basin core, MAL05 - 1C (Fig. 4).

The revised age model for the top 30 m of MAL05 - 1C (Fig. 4) was generated using 15 radiocarbon ages (7) and the latest high - precision YTT age estimate of 75.0 ± 0.9 ka (4) in a Bayesian P - Sequence depositional model (37), run in OxCal version 4.1 (38) with outlier analysis (39) and interpolation at 0.5 m intervals.

Based on the existing age model (24), we targeted a search for cryptotephra (subtle horizons of volcanic glass shards not visually apparent or detectable using remote sensing methods) on the depth interval of 20 — 40 m below lake floor (MBLF) in drill sites MAL05 - 1C and MAL05 - 2A in search of the YTT.
