Technical questions.
Buying questions — grades, samples, packaging, delivery — are answered on the home page.
What is oolitic aragonite?
Oolitic aragonite is a natural calcium carbonate — the orthorhombic polymorph of CaCO₃ — that forms as rounded ooid grains in shallow Bahamian marine waters. AragoCor material analyzes at 96.17% calcium carbonate, with elemental calcium of 38.51% and a specific gravity of 2.93.
What is the difference between aragonite and limestone?
Both share the formula CaCO₃, but they are different mineral polymorphs. Limestone is primarily calcite; AragoCor supplies the orthorhombic aragonite polymorph of marine origin. Crystal form and morphology differ, so supplied grades still need to be compared under the conditions of the intended application.
The aragonite versus limestone technical brief sets the two side by side.
Is AragoCor oolitic aragonite approved for organic farming?
AragoCor natural oolitic aragonite carries OMRI crop fertilizer listing avw-23214 and livestock feed-material listing avw-23215. OMRI Listing is a review of a material’s suitability for use in certified organic production, published by the Organic Materials Review Institute; it is a listing rather than a product certification.
How is oolitic aragonite sourced and processed without calcination?
Material is sourced from naturally forming Bahamian oolitic deposits, then washed, screened, dried and classified into defined particle-size ranges. AragoCor processing uses no quarry blasting and no calcination step, so the mineral is not kiln-converted to lime.
Where is AragoCor oolitic aragonite sourced?
The material is sourced in The Bahamas through Aragosan Minerals Limited, from naturally forming oolitic deposits. Source documentation is available on request.
What are the technical specifications and purity of AragoCor aragonite?
Representative analysis gives 96.17% CaCO₃ and 38.51% elemental calcium, with specific gravity 2.93, surface area > 1.7 m²/g, and sizing published by grade. The full technical data sheet is published on the site and available as a download.
