The mean Ro, ran of pyrobitumen is 2.13%based on 3 measurements. The VRo-equivalent is 1.72%. Organic matter is post-mature and in the dry gas window.

Plate 1 A-D

The above values were measured on pyrobitumen. The VRo-eq is estimated to be 1.72% using the Jacob formula (Rvit = Rbit x 0.618 + 0.4).

P=Pyrite.

General Description: Organic matter (OM) is lean and occurs as pyrobitumen that occupies intergranular space; broken chitinozoan fragments having a pitted surface texture; minor amount of other zooclast fragments; and specks of bitumen staining. A mean Ro,ran of 2.13% measured on pyrobitumen gave an equivalent VRo of 1.72%. A mean Ro,ran of 1.84% measured on the pitted chitinozoan gave equivalent VRo values of 1.53% and 1.62%, using the correlations given by Tricker et al. (1992) (RoVit-eq=(RoChi – 0.08) / 1.152) and Bertrand and Malo (2001) (RoVit-eq=(RoChi – 0.014) / 1.127). All of these VRo values suggest that the organic matter is post-mature and in the dry gas stage of hydrocarbon generation and retention process. The matrix consists of quartz, carbonates, silt/clay, and pyrite.

The above values were measured on chitinozoan fragments. The VRo-eq is estimated to be 1.74% using the correlation of Tricker et al. (1992) (RoVit-eq=(RoChi – 0.08) / 1.152).

(D) Chitinozoan (Ch) showing chamber (Cmb) (ChRo,ran=1.903%).

General Description: This sample is rich in broken parts of chitinozoans. Organic matter also occurs as trace pyrobitumen and bitumen staining. A mean Ro,ran of 2.08% measured on chitinozoans was used to obtain an equivalent VRo of 1.74% using the correlation given by Tricker et al. (1992). The same mean Ro,ran on chitinozoans gave an equivalent VRo of 1.83% using the correlation given by Bertrand and Malo (2001). Also, a Ro,ran of 2.11% measured on a single reliable grain of pyrobitumen gave an equivalent VRo of 1.70%. All of these equivalent VRo values suggest that the organic matter is post-mature and in the dry gas window. The matrix is calcareous and more argillaceous than the previous samples, and contains pyrite.

Nodular packstone; nodules separated by pressure solution. Some nodules contain large fossil fragments, while others are clay-rich and largely devoid of fossils

Fossiliferous black shale with burrows; fossils are in lenses that do not follow bedding planes

Fossiliferous black shale with thin event bed (turbidite/storm?). Small, densely packed fossils

Interbedded grainstone and packstone with slight internal grading and grain size changes between beds

Micrite with elongated organics. Burrowed/bioturbated. Fossils unique when comparedto surrounding strata. Contains a geopetal ostracod (?) with pyrite and calcite

Echinoderm packstone with claystone lenses. Lenses contain pyrite framboids, Fe-oxides anddead oil. Echinoderms show pressure solution features between grains and mud

Micrite with pyrite framboids. Bioturbated--one small burrow observed �lled with pyrite(sometimes re-oxidized to iron oxide) and calcite. Sponge spicules observed.

Fossiliferous black shale with high organic content. Pyrite framboids observed; pyritereplaces some fossil material (e.g. trilobite in �rst image). Bioturbated with lenses of fossil fragments

Black shale with calcite intraclast. Finely laminated claystone and siltstone. Claystonesare partially burrowed with trilobite and ostracode fragments. Siltstone is burrowedand contains a calcite intraclast with burrows and well-formed pyrite. Black shale at base contains ~25% ostracodes, tightly packed

Black shale with peloids and faint burrows. Fossil walls are very thin. Fossils and peloids show extensive post-diagensis distortion and compaction

Black shale, �ssile and �nely laminated. Scattered echinoderm and trilobite fragments. Organic debris is elongated and oriented parallel to bedding.
