粤西大降坪黄铁矿床硫、铅同位素组成初步研究

大降坪黄铁矿床是产于云开隆起中段偏北震旦系海相碎屑岩-细碎屑岩中的层状硫化物矿床,矿床成因和海底喷气热水沉积作用有关,局部经受了后期热液的叠加改造。黄铁矿的δ~(34)S值在-25.55‰—+21.07‰之间,与矿石及黄铁矿中的有机碳含量呈反比。从条带状细粒黄铁矿到块状粗粒黄铁矿,亦即从南到北,硫同位素组成从富轻硫变为富重硫。条带状矿石的铅同位素组成与矿体围岩一致,为富放射成因上地壳源铅,块状矿石铅同位素组成较均一,三组铅同位素比值较条带状矿石略低,为原始沉积的矿石铅与热液带来基底混合岩铅的混合铅。     

试论岩溶在沉积—改造铅锌矿床形成中的作用

在碳酸盐岩地区广泛分布着一些沉积—改造铅锌矿床.其主要改造作用目前一般概括为地下(热)水作用.本文通过比较地下水改造成矿作用与岩溶作用之间的关系,论证岩溶在矿床形成中起着重要作用,即地下水改造富积成矿作用主要为岩溶作用.

The remote sensing observation in experiments of rock failure and the beginning of remote sensing rock mechanics

The remote sensing observational study for infrared radiation of rocks was proceeded during the loading on rocks until failure. The major instruments used in experiments were transient spectrum apparatus, intelligent spectrum apparatus, infrared radiation thermometer, infrared spectrum radiometer, and infrared thermal imaging system. The experiments for 26 kinds of rocks were made. The studies show that infrared radiation temperature of rocks increases along with increasing of stress. The amplitude of infrared radiation spectrum of rocks also increases along with increasing of stress. The observational results of infrared thermal imaging of rocks are consistent with infrared radiation temperature. Before formation of major faults for some rocks, the belt-shape thermal imaging of temperature anomaly displaies in position of future major faults. This study has led the new technology of remote sensing into rock mechanics and tend to establish a new field in rock mechanics — remote sensing rock mechanics (or remote sensing rock physics). The application of remote sensing rock mechanics in prediction of earthquake and rock burst, and in measurement of stress field in rock mass is expected.
