shale and clay. CLAY AND SHALE. Clay is an important raw material in the manufacture of bricks; in fact, it is the main raw material in such manufacturing. Michigan produces many millions of tons of bricks annually. The clay for these bricks comes from two sources: clayey sediments laid down in glacial lakes, and shale bedrock.The meaning of SHALE CLAY is a clay produced by grinding shale and used for brick, tile, and pottery.Due to the existence of water content in shale reservoir, it is quite meaningful to clarify the effect of water content on the methane adsorption capacity (MAC) of shale. However, the role of spatial configuration relationship between organic matter (OM) and clay minerals in the MAC reduction process is still unclear. The Silurian Longmaxi Formation shale samples from the Southern Sichuan ...Scanning electron micrographs of several shales indicate that the shale rocks are comprised of stacks of locally aligned clay platelets (Hornby et al., 1994; Sayers & den Boer, 2019). The stacks are often called domains (Aylmore & Quirk, 1960 ), and this local alignment is a key source of shale anisotropy (Sayers & den Boer, 2019 ).Mudstone - hardened mud; a mix of silt and clay sized particles. The difference between mudstone and shale is that mudstones break into blocky pieces whereas shales break into thin chips with roughly parallel tops and bottoms. The terms shale and claystone are sometimes used interchangeably.
