    Mt. Laurel Formation - Sand, quartz, massive to crudely bedded, typically coarsens upward, interbedded with thin clay beds. Glauconite and feldspar are minor sand constituents. Muscovite and biotite are abundant near the base. Lower part of formation is a fine- to medium-grained, clayey, dark-gray, glauconitic (maximum 25 percent) quartz sand.

    9.12.2.1.1 Glauconites. Glauconite is almost exclusively found in peloidal forms, i.e., ovoid shapes, in sediments, sandstones, and carbonates. The presence of green oval forms is distinctive and usually a good marker for field geologists. Consequently, glauconite-bearing rocks are generally well remarked in descriptions of sedimentary rocks ...

    Ironstone is a general name we give to sedimentary rocks that contain more than 15% iron. These rocks may contain iron hydroxides (limonite), oxides (magnetite and hematite), carbonates (siderite), or silicates (chamosite, Fe-rich chlorite). They generally have a uniform, nonfoliated texture.

    For example, a rock that is entirely made of albite, NaAlSi 3 O 8, a feldspar, has 0% quartz content, but contains 77.3% silica (weight percent).. It was once customary to express the chemical composition of a mineral as an oxide formula (mostly because the structural relationships between the elements involved were not precisely known), and it is still useful if one reflects the silica content.
