The single-grain D values obtained using the standard quality assurance criteria and novel sensitivity tests are consistent at 2σ, and are in agreement with quartz Ti-centre ages obtained on two of three paired electron spin resonance (ESR) samples collected from Cuesta de la Bajada.These comparisons support the suitability of our single-grain OSL results and suggest there may be good potential for using quartz supergrains to establish extended-range chronologies at some Middle Pleistocene sites.
Assessments of OSL signal composition and the ability to successfully recover a known laboratory dose of 470 Gy support the potential for obtaining high equivalent dose (D estimation over high dose ranges related to (i) thermally transferred signal contributions, (ii) choice of dose-response curve fitting function, and (iii) insufficient dose saturation properties of individual grains.
However, there have been relatively few detailed assessments of single-grain OSL properties over high dose ranges.
In this study we investigate extended-range single-grain OSL dating potential at Cuesta de la Bajada, one of the most important Ancient Middle Palaeolithic sites in the Iberian Peninsula.
Comparisons with other single-grain OSL studies across the Iberian central plains suggest that favourable dose saturation properties may be influenced by regional-scale geological controls.
The importance of undertaking single-grain OSL dating at Cuesta de la Bajada is also demonstrated by the results of synthetic aliquot experiments, which reveal multiple-grain age offsets of 60–170 ka when unsuitable grain types are inadvertently included in the final age calculations.
Succeed in the initial phase of something; meet with preliminary approval.
For example, They were delighted that they'd gotten to first base in the negotiations. If someone gets to first base, they succeed in kissing a boyfriend or girlfriend or touching them as a way of starting a sexual relationship.
This term alludes to the first base of baseball, which is the first step toward scoring a run for the batter's team. Note: In baseball, players have to hit the ball and then run round all four corners or bases to score a run.
Here are the bases 1st base: Kissing, making out2nd base: means naked kissing, making out but involves a lot of touching from the waist up 3rd base: Still making out but also touching and masturbating each other, fingering and sucking. But, if she is not comfortable with her partner it isn't going to happen.
Here are the bases 1st base: Kissing, making out2nd base: means naked kissing, making out but involves a lot of touching from the waist up 3rd base: Still making out but also touching and masturbating each other, fingering and sucking. It means sexen as soon as she feels that the time is right.
So the partner has to make sure that she is comfortable with him(her).
I would always talk to guys on the phone in front him just for the satisfaction of seeing him angry.
