Greensand (glauconite) forms in anoxic marine environments that are rich in organic detritus and low in sedimentary input.[1] Having accumulated in marine environments, greensands can be fossil-rich, such as in the late-Cretaceous deposits of New Jersey, USA.

At the broadest level, glauconite is an authigenic mineral and forms exclusively in marine settings.[5] It is commonly associated with low-oxygen conditions.[1]

Normally, glauconite is considered a diagnostic mineral indicative of continental shelf marine depositional environments with slow rates of accumulation. For instance, it appears in Jurassic/lower Cretaceous deposits of greensand, so-called after the coloration caused by glauconite. It can also be found in sand or clay formations, or in impure limestones and in chalk. It develops as a consequence of diagenetic alteration of sedimentary deposits, bio-chemical reduction and subsequent mineralogical changes affecting iron-bearing micas such as biotite, and is also influenced by the decaying process of organic matter degraded by bacteria in marine animal shells. Glauconite forms under reducing conditions in sediments and such deposits are commonly found in nearshore sands, open oceans and the Mediterranean Sea.[1]

If you need large quantities you can get an 8lb bag of greensand on Amazon.
