The study area,an old continent block with a Coledoman folding basement,is located 20-31.5°N,115-122°E,along the southeastern edge of the Eurasian plate.Granite and volcanic rocks are widespread throughout this area with an age decreasing from west to east.The Yanshanian granite exists mainly along the coast and the tectonic activity also shows an increase to the coast.For the coastal area the geothermal gradient and the geotemperature show a higher value ranging from 50-70℃ at a depth of 1000m and 2000m,respectively,and...

The study area,an old continent block with a Coledoman folding basement,is located 20-31.5°N,115-122°E,along the southeastern edge of the Eurasian plate.Granite and volcanic rocks are widespread throughout this area with an age decreasing from west to east.The Yanshanian granite exists mainly along the coast and the tectonic activity also shows an increase to the coast.For the coastal area the geothermal gradient and the geotemperature show a higher value ranging from 50-70℃ at a depth of 1000m and 2000m,respectively,and the highest up to 60℃ and 90℃,somtimes even to 100℃and 130℃.Presented here are some data from the Wuyi Mountains,the Moyang Basin and the Jinqu Basin and the like.Distributions and formation of the geothermal field are dependent on deep structures in the earth's crust and the regional geotemperature,on the crustal thickness as well as on the geological structures.The occurrence and distribution of the hot springs are correlated with two major deep faults striking NE and NW.In addition the content of radioactive elements in the Yanshenian granite is about two times higher than that of the contemporaneous granite found in North China.Two types of geothermal field may be distinguished in the study area:1) conduction and 2) conduction superposed by hot water conduction.

本文从四个方面讨论了东南沿海地区地温场的形成及其分布规律:1.区域地质构造条件,其中着重讨论了岩浆岩的分布及其与地质构造的关系;2.测温资料的分析和处理;3.地温分布的主要特征;4.控制地温场的主要因素。本文除对深部地壳结构及区域地质构造等主要控制因素进行了讨论外,还就岩浆岩中特别是燕山期花岗岩中放射性元素的含量及其蜕变产生热对地温场可能产生的影响进行了探讨。 从而认为东南沿海地区的地温场形成模式主要有传导型的地温场和传导附加以对流型的地温场两种类型。

The Cixian-Chaoyang seismic belt and DanDong—Chaoyang seismic belt is crossed at West Liaoning in the fourth siesmicity period of North China. By gray system theory predicting Seimic risk shows that for earthquake about 6 magnitude to occur in West Liaoning in future is impossible, But is it possible that earthquake of about...

By gray system theory predicting Seimic risk shows that for earthquake about 6 magnitude to occur in West Liaoning in future is impossible, But is it possible that earthquake of about M=7 will occur around West Liaoning in years to come.

辽西位于华北板块北缘,辽西隆起带上,辽西地震活动与华北密切相关,在华北第四地震活动期中,辽西处于磁县—朝阳地震带和丹东—朝阳地震条带交汇处。根据灰色理论预测表明,辽西近期已不大可能发生六级左右地震,但其周围地区近几年很可能发生七级左右地震。

The plate activity in Tianshan can be traced back to Middle and Late proterozoic. The basement of Tianshan continent can be divided into three types, the middle formed in the end of Proterozoic, and the south (incleding north Tarim) formed in Late Proterozoic, whereas the north( including Junger) is nearly the same as that in the middle Tianshan. From the Sinan to the Permian the plate activity in Tianshan is characterized by accordion movement. This area once underwent opening and closing for seven times. A...

The plate activity in Tianshan can be traced back to Middle and Late proterozoic. The basement of Tianshan continent can be divided into three types, the middle formed in the end of Proterozoic, and the south (incleding north Tarim) formed in Late Proterozoic, whereas the north( including Junger) is nearly the same as that in the middle Tianshan. From the Sinan to the Permian the plate activity in Tianshan is characterized by accordion movement. This area once underwent opening and closing for seven times. A suture at one side of the plate is always connected with a tension belt in another side. When the suture was closing, therelated tension belt must be opening at the same time. So they are conjugated in the epposite sides of the plate. The spatial distribution relation of the continent block and its adjacent folded belts in Tianshan area is not accretion relation as in Siberian plate. The Tianshan continent block is a mosaic tectonic area made of several different folded belts and some smaller blocks between them. These folded belts were resulted from the opening and closing of plate, and arranged alternately on both sides of the early Caledonian folded belt in the middle Tianshan. For a folded belt an opening-closing is only one cycle or stage, but for the whole Tianshan area from the Sinian to the Permian several times of opening and classing had made the Tianshan continent block be in motion continuously. The disfanees of block openings in Tianshan had gradually diminished from the Sinian to Permian, If, taking 0.5-1.5cm/y as a rate of block opening, the Early Caleaonian eugeosyncline between the middle Tianshan and southern Hasakstan, would have reached a width of 1000-3000km 500-1500km for the Junger-Beishan Caledonian eugeosyncline, 250—750km for the late Caledonian eugeosyncline in the south Tianshan, 150—450km for the middle Variscan one in the north Tianshan, and 50—150km for late Variscan one in the southern Beishan. Every change in direction of plate oscillation had resulted a openingclosing cycle, so the folded belts are records of change in direction of plate motion during the Sinian to Permian. That is why the cycle of folded belt motion thand the continuity of Plate motion are considered as of dialectic accordance. Tension belt, pressure belt and shear belt are the three elements of plate motion in Tianshan. The front margin of moving plate is a pressure belt, its back margin is Usually a tension belt, and the sides will be shear belts, when the direction of a moving plate changes, its front margin translates into back one, and so are pressure belt and tension belt. This is the pattern of plate motion in Tianshan. The authors we consider that the above-mentioned pattern will be applicable for other plates, for example; the north China plate and the north America plate, in elementary characteristics.

天山地区的板块活动可以追溯到中晚元古代。天山陆壳的基底可分为三种类型,中天山的花岗——变质岩层基底形成于早元古代末;南天山及塔里木北部的基底形成于晚元古代;北天山及准噶尔的基底大致与中天山相同。从震旦纪至二叠纪、天山的板块活动以手风琴式张、合为特征,经历了七次张、合旋回。板块活动的挤压缝合带与扩张带相对应,在时间上,它们“此张彼合”;在空间上,互相对偶,分别存在于板块的对侧。天山(及邻区)陆块与相邻褶皱带的空间关系,不是陆核与边缘褶带的增生关系。天山陆壳是由不同时代的褶皱带及其间的苦干地块坩成的镶嵌构造区。板块张、合所产生的褶皱带及蛇绿岩带,大致以中天山为轴,向南、北方向交错排列。
