Fossiliferous shale.

The Menard Limestone is composed of several layers, 15 to 45 ft thick, of dark argillaceous skeletal limestone separated by somewhat thinner zones of calcareous, fossiliferous shale and siltstone. The Menard is commonly 100 to 140 ft thick and is overlain by 30 to 90 ft of sandstone, siltstone, and shale assigned to the Palestine Sandstone.

Also includes Tioga Metabentonite Bed - Brownish-gray, thinly laminated shale containing sand-size mica flakes; thickness less than one foot; and Needmore Shale - Olive-gray to black shale and dark, thin-bedded, fossiliferous, argillaceous limestone; thickness ranges from 70 to 145 feet.

Nearly 100 m of shale lie below this fossiliferous interval in the Burgess Shale Formation. Assuming 40% post-depositional compaction of strata below the Phyllopod Bed, a conservative estimate for minimum water depth at the time of deposition would be approximately 100 m, essentially the lower limit of the effective photic zone.

It is composed largely of fossiliferous limestones and thin beds of red and gray shale. The general lithology and part of the fusulinid faunas are indicated in the accompanying diagram (Fig. 5). Detailed descriptions of the individual units are given at the end of the report.

Shale is very susceptible to physical weathering due to the ease with which it breaks into planes. However, when buried under the Earth’s surface, shale’s fine-grained matrix can prevent liquids from seeping past, and consequently, shale has held important roles in natural gas and oil exploration.

The difference between it and mudstone is that it is fissile. Fissile means that it tends to split into flat layers.

Some common nonmineral constituent terms are: "tuffaceous," "cherty," "fossiliferous," "crinoidal," "coralline," "clayey (argillaceous)," "silty," "shaly," "sandy (arenaceous)," and "conglomeratic." Minor mineralogy should follow the nonmineral composition and should be restricted to one conspicuous mineral not implied in the root name.
