Geological and Geotechnical Characteristics of Glauconitic Sands
Glauconite is an iron potassium mica with a characteristically green color and low strength, often found in peloidal form. Glauconite generally forms under reducing conditions within a shallow marine depositional environment. It has been observed in coastal regions on the East Coast of the USA, including locations along the Atlantic outer continental shelf (OCS) associated with wind farm developments. Due to its friable nature, glauconite can influence the geotechnical properties of the sandy soils in which it is found. Intact glauconitic sand exhibits high strength, but under moderate disturbance is relatively brittle, similar to carbonate sediments. This paper presents a geological review of glauconitic sand formation, describes its depositional environment, presents some of its geotechnical characteristics, and provides insights into the impact of glauconitic sand on offshore foundation installation and performance.
