and carbonaceous shale and is intercalated with coal seams (M1-M5), while coal seam M5 is recoverable throughout the area.
Core samples of mudstones

Moreover, it is known that sandstones show strong rigidity, while mudstones
The two sandstone bed zones are located 1,100 to 1,200 meters below the ground and 2,400 to 3,000 meters below the ground, respectively, as there are mudstones
on the surface of each of the sandstone beds to seal CO2 and prevent it from emitting outside.
Recently, Edmonton, Canada sub-contractor In-Line Contracting needed a durable, cold-resistant solution to effectively dig through the mudstones
and clays common to the area, while maintaining the strict line and grade requirements needed for a gravity sewer.
They state that in Tasmania, sodic soils have formed predominantly from Triassic and Permian mudstones
and sandstones, Tertiary clays, and unconsolidated Quaternary deposits and reported surface horizon pH values of 5.
Fabrics defined by the alignment of clay particles are widely reported from mudstones
, and generally attributed, if they are bedding-parallel or sub-parallel, to compaction during dewatering and diagenesis (see review in Kisch 1991 and papers by Oertel and Curtis 1972, Moon 1972, Krizek et al.
