Concretion centers are approxi-mately Poisson distributed within the sandstone. The upward-in-creasing cement fraction is caused by upward-increasingconcretion size. Lateral variation in the fraction of the sandstone cemented by calcite has a normal distribution, with a mean of 12% (r 5%).

Though technically a “sand concretion,” gogottes are of a special group of concretions that are only found within the Parisian basin (sometimes referred to as the “Fountainebleau sands”). They also have layered, three-dimensional forms, as opposed to the spherical, discoid, and/or flattened sandstone concretions from other localities.Ironstone concretions are common around Sydney, with its outcrops of iron-rich shale and sandstone. Formation of concretions. The shape of an ironstone concretion often depends on the way a shale or sandstone bed breaks up into regular blocks of various sizes under the action of weathering. 60mm Natural Sandstone Concretion, One of a Kind, Large Sandstone, As Pictured Sandstone Concretion, Unique Moroccan Sandstone Concretion (52.7k) $ 11.00.

Thicker coats are not necessarily better but gaps or breaks in chlorite coats allow quartz cement to grow, albeit at a slower rate than if no chlorite coats were present.
