Songshan World Geological Park has a total area of 464square kilometers. In the park, aggradation and structure, such as magmatic rock, metamorphic rock and sedimentary rock of the 5periods of geologic history, namely 二 Archean Eon, Proterozoic Eon, Paleozoic, Mesozoic and Cenozoic, continuously and completely crop out, relics of angular discordance interface and structural feature fwature by 3 global Precambrian orogeny and epeirogeny respectively called SongYang motion, Zhongyue motion and Shaolin motion taking place 25billion years,1.8billion years and 546million years ago. This park is called by geologists as" natural geology museum ,of" five generations under one roof .

嵩山世界地质公园总面积 464 平方千米，公园内连续完整地出露着太古宙、元古宙、古生代、中生代、新生代五个地质历史时期的岩浆岩、变质岩、沉积岩等沉积和构造，清晰地保存着发生在距今 25 亿年、 18 亿年、 5.46 亿年前被分别命名为嵩阳运动、中岳运动和少林运动的三次全球性前寒武纪造山、造陆运动所形成的角度不整合界面及构造形态遗迹，被地质学家称为"五世同堂"的"天然地质博物馆"。

首次提出元古宙该区的古大地构造性质为诞生于太古宙雏陆壳内及其斜坡的雏陆壳型三岔裂谷系，主要由元古宙长期活动的南北向昆阳地槽型裂谷和早元古宙活动的东西向大红山雏陆壳间裂谷与中晚元古宙活动的盐边—峨边雏陆壳间裂谷组成，并论证了它们的演化—运动史。

Of the eons of geological periods recorded in the stratifications of the earth: of the myriad minute entomological organic existences concealed in cavities of the earth, beneath removable stones, in hives and mounds, of microbes, germs, bacteria, bacilli, spermatozoa: of the incalculable trillions of billions of millions of imperceptible molecules contained by cohesion of molecular affinity in a single pinhead: of the universe of human serum constellated with red and white bodies, themselves universes of void space constellated with other bodies, each, in continuity, its universe of divisible component bodies of which each was again divisible in divisions of redivisible component bodies, dividends and divisors ever diminishing without actual division till, if the progress were carried far enough, nought nowhere was never reached.

349在地球的层理留下记录的太古以来的地质时代。隐藏在大地的洞穴里和能移动的石头底下、蜂巢和土墩子中那无数微小的昆虫类的有机生物：微生物、病菌、细菌、杆菌、精子；凭着分子的亲和之凝聚力而粘在一根针尖上那几万几亿几兆个多不胜数、肉眼看不到的微小颗粒；人类的血浆是一个宇宙，群集着白血球和红血球，每个血球又各自形成一个空虚的宇宙空间，群集着其他球体；各个球体连续性地也是由可分割的构成体形成的宇宙，各个构成体又可以分割成为几个能够进一步分割的构成体。就这样，分子与分母实际上在并未分割的情况下就不断地减少了。如果这个过程延续到一定时候，就永远在任何地方也不会达到零。

Important significance of regional tectonic regime to metallogenic capacity of Indosinian and Early Yanshanian granites in southeastern Hunan:A case study of Qianlishan and Wangxianling plutons;2. Yanshanian movement and conversion of tectonic regime s in East Asia;3. The Sm-Nd isotopic results indicate that the Archean tectonic regime and crust growth in Northern China Platform can be divided into two stages.

Sm－Nd同位素研究结果显示，华北地台太古宙构造体制与地壳生长可分为二个发展阶段：2800Ma以前，地壳以幔源物质垂向增生为主；进入2800Ma以后，地壳物质开始进入地幔，并以水平运动为主要构造体制，反映板块构造机制在太古宙晚期地质演化中具有十分重要的作用。

A series of iron proxies have been suggested to distinguish the redox condition of the paleoocean, by studying iron cycling in the modern ocean. On the basis of this methodology, scientists have reconstructed the redox history of paleoocean since the Archaean as a sequential appearance of the ferrous, sulfidic and oxic ocean.
