Phosphate Nodules

Phosphate Nodules are nodules of sedimentary rock that contain high concentrations of phosphate, represented chemically as PO4^3-. They are solid, discrete masses of phosphate-rich material within sedimentary strata and are characterized by an above-average proportion of phosphate ions compared with surrounding rock.

Phosphate Nodules consist primarily of phosphate-bearing minerals concentrated into compact nodules within sedimentary rock. The defining chemical component is the phosphate anion (PO4^3-), which is present at significantly elevated levels in these nodules relative to typical sedimentary matrix. As a geological occurrence, they appear as distinct lumps or concretions rather than being diffusely distributed through the host sedimentary rock.

• Composition: dominated by phosphate (PO4^3-) concentrated into nodules or concretions.
• Rock type: sedimentary rock nodules or concretions containing high phosphate content.
• Form: distinct, compact masses within sedimentary deposits.

The term appears across multiple language sources with equivalent definitions emphasizing the same core characteristics:

• English: Phosphate Nodules — nodules of sedimentary rock containing high concentrations of phosphate (PO4^3-).
• Korean: 인산염을 고농도로 포함하는 퇴적암 단괴입니다.
• Russian: Фосфатные конкреции — фосфорит, в большом объеме содержащийся в осадочной породе.
• Chinese (Simplified): 沉积岩结晶，含有高浓度磷酸盐。
• Japanese: 高濃度のリン酸塩を含んだ堆積岩の岩塊です。
• German: Knollen aus Sedimentgestein mit hohem Anteil an Phosphat.
• Spanish: Nódulos de roca sedimentaria con alta concentración de fosfatos (PO4^3-).
• Italian: Noduli (PO4^3-) di rocce sedimentarie contenenti spesse tracce di fosfato.
• French: Des Nodules de roche sédimentaire (PO4^3-) contenant de fortes concentrations de phosphate.
• Portuguese (Brazil): Nódulos de rocha sedimentar contendo altas concentrações de fosfato.
• Polish: Bryłki skały osadowej zawierające wysokie stężenia fosforanu.

These descriptions consistently identify Phosphate Nodules as phosphate-rich concretions within sedimentary rock, with the phosphate anion PO4^3- as the chemical hallmark. No additional properties, occurrences, or in-game mechanics are asserted beyond this compositional and lithological definition.
