Holocene ( recent ) the present epoch in the geological time scale , being the second epoch of the quaternary period , dating from the end of the last glaciation , about 10000 years ago , to the present day 全新世：在地质学上指第四纪的第二阶段的整个时期，它终止于最后一个冰川期，距今大约10000年。
Since the last glaciation , with variations in sea level , the development of incised valleys in the hangzhou bay area underwent three stages : 1 ) deep - cutting stage ; 2 ) rapid - filling stage ; and 3 ) rapid - burial stage 末次冰期以来，随着海平面变化，杭州湾地区下切河谷演化经历了深切、快速充填和埋藏三个阶段。
With the uplift of qinghai - xizang plateau and the to - and - fro of the quarternary glaciation and interglaciation , the muscid fauna was distinctly diversified in habitat and vertical zone 青藏高原的横空崛起以及第四纪冰期间冰期的循环往复，导致该地区生境千差万别，使蝇科区系不仅有地域分异，且垂直差异显著。
During the banpo man time or in the middle holocene , 5000 ~ 6000 bp , the climate within the modern glaciation best fitted vegetation and the intrusion of some sub - tropic trees was postulated to have taken place 古土壤代表间冰期夏季风盛行的湿热气候，植被比较繁盛；黄土代表冰期冬季风盛行的干冷气候，植被凋凌。
They rose above the earth surface as a result of movement of the earth s crust over a hundred million years ago . later they underwent the erosion of quaternary glaciation and have gradually become what they are today 一亿多年前的地球地壳运动使得黄山崛起于地面，后来历经第四纪冰川的侵蚀作用，慢慢地就变成了今天这个样子。

Like the better - studied late proterozoic glaciations , the huronian event appears to have been global , based on interpretations that some of the continents were near the equator at the time ice covered them 休伦冰期的相关研究不如其后两次原生代冰期详尽，但从当时位于赤道附近的部份陆地也受冰层覆盖的情况看来，它似乎也是一场全球性事件。
During the quaternary period , spanning the last 2 million years , major glaciations in polar regions affected global sea level , which fell to 120metres below present level , leaving the site of present - day hong kong as much as 130 kilometres from the coast 长达200万年的第四纪期间，全球海平面受到两极地区几次大冰期的影响，曾下降至现时海平面之下120米，当时的海岸线离开现时本港海岸达130公里。
