我试着在怀疑是三角洲的地方带一个光释光样本，并带一些样本用于晶粒尺寸分析。

I managed to take one optically stimulated luminescence (O.S.L.) sample at the suspected delta, as well as a few samples for grain size analysis.

从疑似三角洲沉积物中提取的光释光样本能提供给我们信息，滑坡沉积物何时发生，湖泊何时形成。

sample from the suspected delta deposit could give us information on when the landslide happened and the lake formed.
