Phosphate Rock Of Seamount

Chapter 3 Phosphorite on Seamounts ScienceDirect

Jan 01, 1981The main type of phosphorite on seamounts is phosphatized limestone. In particular, on the Marcus-Necker Ridge there are rudist, bioclastic-calcarenite, and phosphatized nannoplanktonic foraminiferal limestones, usually coated with crusts of iron and manganese hydroxides. Siliceous-phosphatic rocks are a relatively rare rock type on seamounts.

Phosphatic Rocks and Manganese Crusts from Seamounts in

Manganese oxide occurs in the phosphate matrix in the form of dendritic growths, as a coating on intraclasts, and as infillings in foraminifers and algal tissues. Weathered clasts derived from mafic igneous rocks are the dominant constituents in the samples from Tuvalu seamounts and phosphate occurs mainly as a cementing material for these clasts.

Phosphate Rock an overview ScienceDirect Topics

Phosphate rock used for fertilizer is a major NORM due to both uranium and thorium. Phosphate is a common chemical constituent of fertilizer. It is principally mined from apatite and phosphate rocks (phosphorite) in which the concentration of phosphate has been enhanced by sedimentary, igneous, weathering, and biological processes.

Phosphate and How Florida Was Formed

Phosphate rock was first mined in England in 1847 for use as a fertilizer. It was in 1881 that Captain J. Francis LeBaron, of the Army Corps of Engineers, discovered Florida’s treasure in black phosphate pebbles in the Peace River. A “hard rock” phosphate reserve in North Central Florida was discovered next.

Phosphorite Wikipedia

Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate minerals.The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P 2 O 5).Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than 30% P 2 O

Seamount Wikipedia

A seamount is a large geologic landform that rises from the ocean floor but that does not reach to the water's surface (), and thus is not an island, islet or cliff-rock.Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to 1,000–4,000 m (3,300–13,100 ft) in height. They are defined by oceanographers as
