false. T/F? Black volcanic beach sand is a type of hydrogenous sediment. False. The similarity found in marine microbe populations near the ocean urface and on the ocean floor, despite the 10 to 50 years it takes for an individual organism to sink to the abyssal depth, can be explained by. being concentrated in fecal pellets.Oolites are small, sand-sized spherical or oval grains that form as hematite precipitates from fluids. Typically oolites consist of thin concentric crystal layers that, on broken surfaces, appear as nested spheres or ovals. When not broken, hematite oolites appear to be red, well-rounded sand grains or may be mistaken for lithified fish eggs. ...Oolites and algal stromatolites occur throughout unit. Shaly dolomite increases downward towards lower conformable contact with the Leithsville Formation. Unit does not crop out but is known from subsurface borings near Flanders (Volkert and others, 1990). Thickness ranges from 0 to 73 m (0-240 ft) due to erosion.The ooids vary in size from 0.5 mm to 2.0 mm, but are generally smaller at the base of the unit and larger towards the top. The lower oolites occur in a mixed siliciclastic-carbonate matrix (Fig. 5 A) while the upper examples are surrounded by neomorphic spar (Fig. 5 C). Common nuclei include quartz grains, echinoderm plates, hyolith tests ...

[2] Strictly, oolites consist of ooids of diameter 0.25–2 millimetres; rocks composed of ooids larger than 2 mm are called pisolites.

Silicified oolitic limestone from the Cambrian of Pennsylvania, USA. Oolitic limestones are whitish to cream-colored limestones composed of sand-sized (= 1/16 to 2 mm in size), well rounded, concentrically-layered calcite or aragonite grains called oolites (also known as ooliths or ooids). Oolites form by rolling back and forth on a shallow seafloor, or sometimes on a shallow lake bed, by wave ...Batu gamping (batu kapur atau limestone) kebanyakan merupakan batuan sedimen organik (biologis) yang terbentuk dari akumulasi cangkang, karang, alga, dan pecahan-pecahan sisa organisme.
