大兴安岭东坡中段遥感影像特征与区域成矿预测标志

大兴安岭东坡中段的铜多金属矿产分布，ＮＥ成带，ＥＷ成行，ＮＷ成列，并构成多个矿化－构造带、矿化－构造块体，矿化－构造结。主要是受到区域ＮＥ向与ＥＷ向构造带构成的构造大格局和ＮＷ向与ＳＮ向构造带形成的构造小格局组合而成的“菱格网”状构造所控制。区域构造格局是铜多金属矿成矿构造的基础，据此区域性的遥感成矿预测，指出北段以找铜为主，中段以扩大银铅锌远景为主，深部找铜以及南段深部找铜的找矿方向。     

无锡、常州郊区发生地裂缝

无锡、常州郊区发生地裂缝近年来，无锡石塘湾西蔡一秦村～带、常州横林分别出现了地裂缝，其中以钱桥毛村园最为严重，该处地裂缝于１９９１年夏初步形成，随后不断扩大，目前已具一定规模，长约７００ｍ，总体宽约６０ｍ，呈近东西向分布，并造成附近数十间楼房产生大量...     

Hydrous pyrolysis of a Type III source: fractionation effects during primary migration in natural and artificially matured samples

A core from the Cambay Shale Formation of the Cambay Basin, containing immature Type III organic matter, was pyrolysed at 300°C for different durations of time to different maturation levels. Fractionation effects were studied employing a three-step extraction technique after removal of the expelled pyrolysate. The extractable organic matter (EOM) obtained on extraction of the whole core is assumed to be that present in open pores, while that obtained on finely crushing the sample is assumed to be that present in closed pores. The EOM obtained from 1 cm chips is termed EOM from semi-open pores. The gross composition of the pyrolysates expelled during pyrolysis is not similar to the oils reservoired in the area, and there is no significant fractionation observed between expelled pyrolysates and unexpelled EOM. Our study indicates movement of fluids between closed, semi-open and open pores. In both systems, there is a higher concentration of EOM in open pores than in semi-open and closed pores, and the fraction of EOM in open pores is much greater in the artificial system than in the natural system. Fractionation effects on n-alkane and isoprenoid hydrocarbon-based parameters were also studied. n-Alkenes are present in semi-open and closed pores of the immature core and in the core after it was pyrolysed to 300°C for 6 and 48 h, but are absent in the open pores. n-Alkenes are present in closed pores in the naturally matured core. Presence of n-alkenes in the pyrolysates expelled during the 6 and 48 h experiments, but their absence in the open pores of the core, indicates that expulsion also occurs through temporary microfractures during laboratory pyrolysis, whereas in the natural system expulsion from closed pores seems to be only via semi-open and open pores.     

地震CT及其地质解释

在金川公司龙首矿东采区1 280中段井下500m深的巷道中应用地震CT技术进行寻找深部隐伏矿体的实验。波速图像表明,研究区内中西部有一高速异常区,推断为花岗岩体和含矿的超基性侵入岩体。区内还有一个横贯测区中央近东西走向的低速断裂带。这些推断结果为后期的钻探和巷道开掘所证明。
