Specifically, mud is composed of silt -sized particles that are between 1/16 - 1/256 ( (1/16) 2) of a millimeter in diameter, and clay-sized particles which are less than 1/256 millimeter. Mudrocks contain mostly clay minerals, and quartz and feldspars.Lime mudstone facies (B1): The facies consist of pale-gray compact carbonate rocks. It has been affected by dolomitization that formed suture-mosaic and sieve-mosaic fabrics. Where dolomitization of the mudstone was complete, a micro-texture sutured mosaic was formed (Randazzo and Zachos, 1984) that contains ghosts of miliolids.Mudstone. Mudstone or mudrock, previously and more commonly termed shale, can form thick intervals in deepwater settings, ranging from several cm to kilometers in thickness ( Potter et al., 2005 ).
