Based on this study, a summarization has been made on the temporal and spatialdistribution regularity of the Mesozoic granitoids and their comprehensive characteristics, and adiscussion done not only on material source and geological and tectonic setting for the formationof the granitoids but also on their petrogenesis.

在此基础上，本文初步总结了区内中生代花岗岩类的时空分布规律和综合特征，探讨了其物质来源和形成的地质构造背景，讨论了它们的成因。

Statistic analyses of accurate chronological and geochemical data of igneous rocks show that the chronological frames of large-scale late Mesozoic magmatism in the Dabie Mountain and middle-lower Yangtze River belt are the same, with different character of magma and petrogenesis.

年代学资料和地球化学指标的统计表明，长江中下游成矿带与大别山地区晚中生代岩浆活动在时间上是同步的，但二者岩浆性质和成因机制不同。

Dated from Proterozoic to Mesozoic, they have poly-circle characteristics, found from one tectonic circle to another, which is very rare in the worldwide orogens. This reveals that the orogen and stable area of the world, the mantle and crust states of the Proterozoic and Phanerozoic are different in tectonic evolvement and dynamic process and that the rapakivi granite of the Qinling-Kunlun is a kind of orogenic granite different from the stable area of the Proterozoic.

它们出现在每一个大的造山旋回晚期，即向另一个构造旋回的转折期，这在世界造山带中是十分罕见的，反映出世界上造山带与稳定区元古宙和显生宙的地慢与地壳状态是不一样的，有着不同的构造演化历史和动力学过程，表明秦岭－昆仑地区的环斑花岗岩是一种有别于元古宙稳定区的造山型环斑花岗岩。

The Dabie Mountains are unique among ultrahigh pressure metamorphic terranes in having the most profound post collisional plutonism The Mesozoic shoshonitic and calc alkaline intrusive rocks can be divided into three groups with different isotopic ages, rock assemblages and chemical features Group I consists of late Triassic (~ 210 Ma) mafic monzodiorites It could have been generated by partial melting of enriched subcontinental lithosphere mantle due to slab breakoff Group II consists ma...

第 I组，主要由晚三叠世（约210 Ma）二长闪长岩辉长岩体组成，它可能是在板片断离过程中富集的大陆岩石圈地幔部分熔融的产物；第I I组，由中侏罗世－早白垩世（160～120 Ma）的角闪石英二长岩、黑云母二长花岗岩和正长花岗岩组成，主要是由幔源岩浆的分离结晶与地壳混染共同作用的产物；第II I组，以白垩纪（125～95 Ma）的花岗岩和花岗斑岩为代表，是在热穹窿作用过程中大别杂岩深熔作用和高度演化的产物。

Lower Plate units contain Proterozoic through to Mesozoic rocks which have been variably metamorphosed and altered.

下板单元包含古代到中生代岩石已变变质和改变。

These source rocks developed with strata from Middle Proterozoic to Cenozoic,among which the Mesozoic and Cenozoic layers are the most important.

在地质时代上，从中元古代到新生代均有烃源岩分布，最重要的是在中、新生代。

Darwinopterus is a pterosaur, a member of the group of reptiles that soared above the landscape for much of the Mesozoic era.

Darwinopterus 是一只翼龙，这是大多数时间翱翔在中生代天空中的一类爬行动物。

Gregory Paul, in a 1989 article, compared known impacts and super eruptions of the Mesozoic with radiations of the major pterosaur, dinosaur, and bird groups to see if a pattern could be identified.

格雷戈里·保罗在1989年发表的一篇文章里，比较了当时已知的中生代的撞击与火山活动，用发光法测定了翼龙、恐龙和鸟类种群，试图找出一个固定的模式。

Microfossils, including spores, pollen and radiolarian, were found in the Mesozoic which was first encountered in Well MZ-1-1 in the north of the South China Sea.

MZ-1-1钻井首次在南海北部珠江口盆地揭示了中生界，获得了可确定地层时代和沉积环境的孢粉和放射虫化石。

If this explanation is correct, the present lithosphere mantle in the North China block is mainly the relict after the Mesozoic lithospheric thinning, rather than the new accreted mantle.

华北岩石圈地幔的低水含量有可能是由于上升软流圈的热侵蚀造成的，因此目前的华北岩石圈地幔可能大部分都是中生代岩石圈减薄后的残余，而不是新生地幔。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。

The factory affiliated to the Group primarily manufactures multiple-purpose pincers, baking kits, knives, scissors, kitchenware, gardening tools and beauty care kits as well as other hardware tools, the annual production value of which reaches US$ 30 million dollars.
