Examples of sedimentary rocks include limestone, sandstone shale and mudstone. Sandstone is rough to the touch, porous and its sedimentary layering is often visible.

Abstract. Abstract The well‐known earthquake‐and‐storm‐triggered extremely high physical weathering rate in Taiwan is consistent with present geochemical studies of sediments from different ...

Now, four researchers, all at the University of Tsukuba in Japan, have analysed sedimentary rocks in a subduction zone that existed in the Jurassic period but which are now exposed to the surface.

This is a beginner's guide to identifying UK rock types. The guide has two main sections: background information on the structure and forces affecting the Earth in relation to rock formation; a more ...
