Tiger Tail        28°47.015’N, 82°38.448’W

Florida, United States

Find: 1 Mar 2015

Classification: Ordinary chondrite (L3-6)

History: On March 1, 2015, around 10 am, a single wedge-shaped 39 gram stone (~39 mm by 31 mm) was recovered along a shell beach close to the edges of the Homosassa River by Susan Davies, who was kayaking near Tiger Tail Island and Tiger Tail Bay. When initially recovered, the stone was dry with some shell/sand residue still attached. The stone resided in the collection of Susan and Charlie Davis until April 2022, when it was cleaned and a 5 mm window was cut, revealing metallic flecks and round granules. On May 18, 2022, a slice was sent in for classification.

Physical characteristics: Single stone with slightly weathered dark brown fusion crust.

Petrography: (D. Sheikh, Cascadia) Sample is a genomict ordinary chondrite comprised of variably-sized chondrules (Av. ~0.65 mm, up to 2 mm), lithic fragments, and isolated melt regions set within a fine-grained matrix containing accessory merrillite, chlorapatite, Fe-Ni metal, and troilite. Compositonally, the sample contains both unequilibrated and equilibrated lithologies, with some well-defined POP chondrules displaying zoned olivine/pyroxene and partially devitrified mesostasis, other chondrules having equilibrated olivine and devitrified glass, and matrix regions containing equilibrated olivine/pyroxene and variably-sized secondary recrystallized feldspar (Av. ~30 μm, up to 75 μm).

Geochemistry: Unequilibrated Lithologies [Olivine (Fa23.1±5.3, range Fa11.9-33.4, n=41), Low-Ca Pyroxene (Fs16.1±6.2Wo1.1±0.7, range Fs4.6-21.5Wo0.2-3.1, n=32)]; Equilibrated Lithologies [Olivine (Fa24.7±0.7, range Fa23.9-27.0, n=34), Low-Ca Pyroxene (Fs20.5±0.3Wo1.3±0.4, range Fs19.8-21.1Wo0.6-2.0, n=19)].

Classification: Ordinary Chondrite (L3-6).

Specimens: 8.1 grams at Cascadia, main mass with Susan and Charlie Davis.
