This may pass laterally through flank facies (around the periphery of mounds) and into laterally equivalent off-bank facies, which is generally composed of interbedded argillaceous limestones,...
A Multi-Phasic Perspective of the Intact Permeability of the
The Cobourg limestone is a heterogeneous argillaceous rock consisting of lighter nodular regions of calcite and dolomite, interspersed with darker regions composed of calcite, dolomite,...
Argillite
Grey chunks of graptolitic argillite on Pakri Peninsula, Estonia; yellowish and white chunks are limestone. Argillite (/ ˈɑːrdʒɪlaɪt /) is a fine-grained sedimentary rock composed predominantly of indurated clay particles. Argillaceous rocks are basically lithified muds and oozes.
Argillaceous Rocks Examples (Characteristics and Types)
Argillites or argillaceous rocks are fine-grained sedimentary rocks composed mainly of clay. There are a variety of silt-sized particles in argillaceous rocks made from lithified muds and oozes. When the fissile layering characteristic of shale develops, the argillites grade into shale.
Classification of Sedimentary Rocks
Graywacke currently has two meanings. To some, it denotes a feldspar-quartz sandstone with more than 20 (or 15) percent pelitic matrix. To many others, it has retained its original meaning; that is a very hard, firm sandstone without porosity or chemical cement.
The thermo-hydro-mechanical behavior of the argillaceous Cobourg Limestone
The Cobourg Limestone is a low-permeability argillaceous rock that forms a part of the Paleozoic sedimentary sequence found in southern Ontario, Canada. The limestone has a heterogeneous fabric consisting of nodular regions of calcite and dolomite and argillaceous partings of a similar composition but with a low clay content, which gives the ...
Argillaceous limestone: Mineral information, data and …
About Argillaceous limestone Hide. A limestone containing an appreciable amount (but less than 50%) of clay; e.g., cement rock. Ref: AGI.
KGS--St. Louis Limestone--Core Descriptions
Argillaceous limestone. The argillaceous limestone lithofacies (lithofacies 2) is a thin, laterally extensive unit, characterized by thin bedded, often fissile, olive-green to gray argillaceous limestone, which is primarily wackestone or packstone with abundant bryozoans, crinoids, minor brachiopods, and ostracods (figure 3).
A textural classification of argillaceous rocks and their …
In this paper, we propose a classification of argillaceous rocks based on their textural characteristics. Three main components of the classification scheme are the clastic framework, the fine-grained matrix, and the cementing agent.
Clay mineral
Argillaceous rocks are those in which clay minerals are a significant component. [37] For example, argillaceous limestones are limestones [38] consisting predominantly of calcium carbonate, but including 10-40% of clay minerals: such …
