That close-shaven turf, those pebbly paths, that chalk, those pools, those harsh monotonies of waste and fallow lands, the plants of early market-garden suddenly springing into sight in a bottom, that mixture of the savage and the citizen, those vast desert nooks where the garrison drums practise noisily, and produce a sort of lisping of battle, those hermits by day and cut-throats by night, that clumsy mill which turns in the wind, the hoisting-wheels of the quarries, the tea-gardens at the corners of the cemeteries; the mysterious charm of great, sombre walls squarely intersecting immense, vague stretches of land inundated with sunshine and full of butterflies,--all this attracted him.

In practical study, the essential flow is""on the basis of the study of the faults, strata denuded thickness and original thickness, analyzing the controlling effect of the faults to the sedimentation and denudation, and combined with the areal geology background, reconstructing the basin prototype of each stage"". 2. As the basic theories and methods of the calculation of the denuded thickness, such as, the methods of cosmogenic nuclides, wave equation, apatite fission track, structural sections, acoustic wave, vitrinite reflection, etc, were argued detailedly , and their applicable ranges were analyzed , the denuded strata thickness of each structural layer layer of pre-Tertiary was reconstructed.

The study of natural fullerenes is a new area of across fullerene science and geological science. So far natural fullerenes have been found in shungite, fulgurite, carbonaceous conglomerates in impact crater, E/K boundary carbonrich clay rock layer, T/P boundary layer, dinosaur eggshell, coal, heavy crude oil, solid bitumen and socalled seminatural fullerenes in common soots, Chinese ink sticks, commercial char, et al., only with low concentrations.

天然富勒烯研究是富勒烯科学和地质科学相交叉的一个新兴研究领域，迄今为止已在桑加岩、闪电熔岩、陨石撞击坑中的含碳质角砾岩、古近系/白垩系地层界线的含碳粘土岩、三叠系/二叠系界线岩石、恐龙蛋壳、煤、重质油、固体沥青以及半天然的烟灰、木炭、书墨等物质中检测到富勒烯的存在，但含量很低。

SHRIMP U-Pb concordia ages of the cores of rounded zircons are 620 and 219 Ma, suggesting that the parental magma for the quartz diorite porphyry may have been derived from partial melting of basement materials of the South China block that had been modified by ultrahigh-pressure metamorphism.

具有细微震荡环带岩浆锆石的SHRIMP U-Pb年龄(117.7±1.6 Ma)显示该石英闪长斑岩体的形成时间为早白垩世；浑圆状锆石核部SHRIMP U-Pb谐和年龄为620 Ma和219 Ma，这表明该石英闪长斑岩的母岩浆可能起源于经历了超高压变质作用改造的华南地块基底物质的部分熔融。

The flare of the gas-jets, the open trunks, suggestive of travel and display, the scattered contents of the make-up box -- rouge, pearl powder, whiting, burnt cork, India ink, pencils for the eyelids, wigs, scissors, looking-glasses, drapery -- in short, all the nameless paraphernalia of disguise, have a remarkable atmosphere of their own.

耀眼的煤气灯，打开的箱子，散乱的化妆用品――胭脂、珍珠粉、白垩粉、软木炭、墨汁、眼睑笔、假发、剪刀、镜子、戏装――总之，各种叫不上名来的化妆用的行头，应有尽有，各有自己独特的气息。

By means of the comprehensive study of the petrified wood,other plant fossils and rock groups,some principal characteristics of the ancient climate in SE China are .

根据浙江省新昌硅化木的分布与特点，应用硅化木记录的可知性和植物学的类比原理，通过该地区硅化木、其他植物化石和岩性组合等综合分析，初步探讨了早白垩世新昌盆地南洋杉型木的生态环境，以此研究该时期东南沿海地区的古气候主要特征。

The traveller from the coast, who, after plodding northward for a score of miles over calcareous downs and corn-lands, suddenly reaches the verge of one of these escarpments, is surprised and delighted to behold, extended like a map beneath him, a country differing absolutely from that which he has passed through.

那个从海岸走来的游客，向北面跋涉了二十几英里的路程，才走完白垩质的草原和麦地。他突然走到一处悬崖的山脊上，看见一片田野就像一幅地图铺展在下面，同他刚才走过的地方决然不同、不禁又惊又喜。

从海岸徒步北上的游客，在跋涉了二十多英里路程，越过了白垩质的草原和玉米地之后，突然来到这样一座悬崖边上，发现一种跟他适才走过的地区截然不同的景色像地图一样展现在他面前时，是免不了会惊喜交加的。passed through：经过市镇等此处country指田野fields。

In addition, the activities of Tan-lu fault (two times of left-lateral strike-slip in Mesozoic, extension from later Jurassic to Eogene and thrusting during Neogene) have an important influence on basin type, tectonic framework, sequence-filling succession, and formation of different types of tectonic belts in Hefei basin during Mes-Cenozoic.

郯庐断裂中生代的两次左旋走滑、晚白垩-古近纪时期的伸展运动及新近纪以来的逆冲活动对合肥盆地中新生代的盆地类型、构造格架、沉积充填序列以及不同类型构造带的形成等均具有重要的影响和控制作用。
