页岩中的纹理是一个能提供有关古沉积环境和沉积作用信息的重要特征。大不列颠岛约克郡的托阿尔阶(J_1)页岩纹理类型的变化反映了沉积作用的变化.X射线照像法、岩相学和扫描电镜技术揭示了侏罗系深灰色(“灰色页岩”)和黑色(“煤玉岩”和“沥青页岩”)页岩中的三种纹理类型.薄纹理形成于较深水的厌氧远岸环境,在这种环境中主要盛行悬浮沉积作用.厚纹理指示了浅水底流的影响.波状纹理产生于底栖微生物席的作用.托阿尔阶海进页岩序列表明:从厚纹层到波状纹层再到薄纹状的逐渐变化与该环境中沉积作用的逐渐变化有关.各种独特的与纹理共生的宏、微组构类型提供了一个对解释页岩形成条件有用的参考框架.
Texture in shale is an important feature that provides information about paleo-sedimentary environments and sedimentation. Changes in shale texture types in Yorkshire, Great Britain, indicate changes in sedimentary facies. X-ray photography, petrography, and scanning electron microscopy revealed the Jurassic dark gray (“gray shale” ) And black (“Jadeite” and “Asphaltic Shale”) shales, which are formed in the anaerobic apogee environment of the deeper water where the suspension sedimentation is predominant The texture is indicative of the effects of shallow underflow, and the wavy texture is produced in the benthic microbiological mattes.The sequence of the Tuareg marine shale shows that the gradual change from thick layer to wavy layer to thin grain and the deposition in this environment The role of a gradual change.A variety of unique and texture symbiotic macro and micro-structure type provides a useful explanation for shale formation conditions.
