For unconventional … WitrynaBlack Shale Siderite rich shale . Pyrite: has a magnetic susceptibility which is virtually zero (+0.837 x 10""8 SI; Bleil k Petersen 1987). This means that pyrite has essentially no effect on measured susceptibility values in ancient organic carbon-rich mudrocks. - Ferroan calcite and dolomite can have fairly high susceptibilities. ...
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2Si2O5(OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite. Shale is characterized by its tendency to split into thin layers … Zobacz więcej Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable bedding planes. … Zobacz więcej The fine particles that compose shale can remain suspended in water long after the larger particles of sand have been deposited.
