The faster the medium flows, the larger the particles it can move. This is illustrated in Figure 6.1. 3.

Lithofacies were divided into 12 types, based on rock type, sedimentary structure, and other related factors. The sedimentary environment was determined by analyzing the color of the mudstone.
WebMudstone is a general term for rocks made of sediment grains smaller than sand (less than 2 mm). Rocks that are fissile, meaning they separate into thin sheets, are called shale. Rocks exclusively composed of silt or clay sediment, are called siltstone or claystone, respectively. These last two rock types are rarer than mudstone or shale.
