A mishmash of several rock types including siltstone, gypsum, and a seastack exposing a 'scapolite pegmatite'. Described as a 'melange' by Bromley (1987) and a 'megabreccia' by Gibbons and Murphy (1995).

ⓘ ~~Prehnite~~

Formula: Ca₂Al₂Si₃O₁₀(OH)₂

Description: Traill is simply a collection of previous literature references. It is unclear what the original reference to this mineral at this location is. However Marsh (Marsh, O.C. (1863) "Catalogue of Mineral Localities in New Brunswick, Nova Scotia, and Newfoundland", American Journal of Science and Arts, Second Series, vol. 35, no. 104, art. 23) already lists it and specifically mentions in his text that it is a doubtful occurrence. There are no descriptions, analyses, or specimens to suggest it was ever found here.

ⓘ Pyrite

Formula: FeS₂

Habit: Pyritohedrons, cubes, highly complex microcrystals.

Colour: Brass-colored

Description: In 2004 some very complex crystals were found in a gypsum boulder. These are quite tiny, perhaps in the range of 100 microns. One of these was measured by Peter Richards on a goniometer. Forms included {100}, {111}, {210} (uneven faces, but consistently present), {211}, {321}, and {10 5 2}. Despite the unusually high indices of the {10 5 2} measured form, the fact that it is a bevelled edge between {210} and {211} makes it reasonable.

ⓘ Quartz

Formula: SiO₂

Description: Henry How (Mineralogy of Nova Scotia, pg 203) lists pseudomorphs of quartz after stilbite. Nothing more is said about them. None are known to have survived from those early finds. Tiny (approx 1 mm) perfectly transparent floater quartz crystals, seemingly authigenic, in massive gypsum matrix, associated with floater tourmaline of similar size and highly complex floater pyrites.

ⓘ Rutile

Formula: TiO₂

ⓘ Titanite

Formula: CaTi(SiO₄)O

Colour: Green-yellow

References:

ⓘ 'Tourmaline'

Formula: AD₃G₆ (T₆O₁₈)(BO₃)₃X₃Z

Habit: Floater, prismatic hemimorphic crystals.

Colour: Olive green

Description: Tiny (~1mm) but perfectly formed sharp euhedral floater crystals. Transparent olive green in color. The Raman fit was best for dravite but could be one of several other tourmalines. Found in a gypsum boulder with tiny floater quartz crystals and muscovite in square prisms (apparently pseudomorphing some other mineral). Possibly authigenic.
