ABSTRACT: Mudstone phosphorites eoliophane mudstones and miniposed of phosphate coated grains from the Duchess phosphate deposit of early Middle Cambrian age in theina Basin, Australia, are described in detail. The mudstone phosphorites form thin beds and laminae, interlayered with transported peloidal phosphorites.
Theina Basin is a large late Proterozoic to Early Palaeozoic sedimentary basin covering a large part of the eastern Northern Territory and extending into northwest Queensland. Australias largest phosphate deposits are confined to the shallow marine Cambrian aged sediments of theina Basin.

Within theina basin the Duchess Deposit in Northern Queensland was in production between 1975 1978 and 1981 1982. The total resource at Duchess is 1000mt @ 17 18 P 2 O 5, DSO is = 30 P 2 O 5 . Phosphate Rock occurs as an agglomeration of apatite either as fluroapatite FP 2 O 5, aphanic apatite, microcrystalline apatite and crystalline apatite. Tenement details are given in Table 1

Phosphorites recognized in oil wells in the southeastern part of the Basin, Queensland, led to the discovery of the Duchess deposits. Exploration of the Beetle Creek Formation since 1966 has disclosed nine other sizeable deposits north of Duchess around the eastern margin of the Basin.

The small island nation of Nauru and its neighbor Banaba Island, which used to have massive phosphate deposits of the best quality, have been mined excessively. Rock phosphate can also be found in Egypt, Israel, Western Sahara, Navassa Island, Tunisia, Togo, and Jordan, countries that have large phosphate mining industries.

The Phosphate Hill deposit is located ~50 km south of the town of Duchess and ~140 km SSE of Mount Isa in Northwest Queensland, Australia. It one of a generally north south, 6 km long string of similar deposits distributed over an area of ~180 sq. km that constitutes the Duchess phosphate field.

Drilling in the Rogers Ridge area, near the Duchess phosphate deposit, has also clarified the stratigraphic significance of concretions that straddle the boundary between the younger Beetle Creek and Inca formations. They appear to represent a sediment bypass surface with evi dence of transgression and locally condensed sequence.

Deposits which contain phosphate in quantity and concentration which are economic to mine as ore for their phosphate content are notmon. The two main sources for phosphate are guano, formed from bird droppings, and rocks containing concentrations of the calcium phosphate mineral, apatite. As of 2006

Phosphate Hill is a world class phosphate rock deposit that is easy to mine because it is so close to the surface. It is used for the manufacturing of mono ammonium phosphate MAP and di ammonium phosphate DAP that is used for fertilisers for both international and domestic use. Other places where phosphate is mined in Australia are:
