Alphabetical List Tree DiagramDetailed Mineral List:
| ⓘ Calcite Formula: CaCO3 Habit: massive, intergrown Colour: transparent, white, cream, red Description: Calcite forms the basis of many of the nodules and th rhizo-concretions at this location.
May be pseudomorphous after gypsum/anhydrite in places. References: |
| ⓘ Erythrite ? Formula: Co3(AsO4)2 · 8H2O Habit: earthy, encrusting Colour: pink Description: Minute, pinkish crusts on black nodules after allowing to dry out thoroughly have been tentatively identified as erythrite as being comparable to the material seen on the similar nodules from Budleigh Salterton. References: |
| ⓘ 'Limonite' Habit: massive Colour: ochre yellow Description: Well-rounded pebbles of pure sulphide minerals have given rise to pure, pigment grade limonite.
Analysis is probably close to pure hydrated Fe(III) hydroxide.
The presence of limonite is significant as all other iron oxides have been converted to nano-particles of hematite as part of the deposition process. References: |
| ⓘ Metatyuyamunite ? Formula: Ca(UO2)2(VO4)2 · 3H2O Habit: bladed, earthy Colour: yellow Description: Seen as minute, yellowish crusts of tiny crystals on the surface of black nodules. Tentatively identified through similarity with the mineral as seen on the Budleigh Salterton nodules. References: |
| ⓘ Metavivianite ? Formula: Fe2+Fe3+2(PO4)2(OH)2 · 6H2O Habit: botryoidal, encrusting Colour: bottle green to greenish-black Description: Seen as bottle-green to greenish-black encrustations on surfaces and within fractures.
Tentatively identified as metavivianite through inference from understood local chemistry and similarity to other occurrances. References: |
| ⓘ Quartz Formula: SiO2 Habit: Massive, prismatic Colour: white, yellowish Description: Many of the clasts comprising the basal conglomerate and subsequent breccias are composed of broken quartz veins.
Isolated crystal ponts may occasionally be found in the breccias. References: |
