Comparison of δ 98/95 Mo in two Devonian shale sequences of similar age, the New York Oatka Creek and Geneseo Formations, reveals that this assumption cannot be applied to all organic-rich shales. Although both sequences contain laminated...

Generalized chronostratigraphic chart for Middle–Late Devonian strata of New York (Wilson and Schieber, 2014, 2015). The Geneseo Formation marks the onset of the third tectophase of the Acadian orogeny. Thrust loading and cratonic downwarping coincided with a major transgression (transgressive–regressive [T-R] cycle IIa). The Genesee Group onlaps the Taghanic disconformity westward; thus, the ages of the onlapping Geneseo and Penn Yan Shales become progressively younger westward. BUF = Buffalo; CAN = Canandaigua; GEN = Geneseo; ITH = Ithaca; mbr. = member; SHB = Sherburne.

Generalized chronostratigraphic chart for Middle–Late Devonian strata of New York (SHB, Sherburne; ITH, Ithaca; CAN, Canandaigua; GEN, Geneseo; BUF, Buffalo; HAM, Hamilton Group). The Geneseo Formation marks the onset of the third tectophase of the Acadian Orogeny (Ettensohn 1987), the most pronounced thrust loading event of that orogeny. The Genesee Group onlaps the Taghanic disconformity westward; thus, the basal ages of the onlapping Geneseo and Penn Yan shales become progressively younger westward (Kirchgasser et al. 1988). Figure is modified from Rogers et al. (1990) and includes data from Baird and Brett 1986, 1991; Baird et al. 1988; Brett and Baird 1996; Brett et al. 2011; Bridge and Willis 1991, 1994; and Kirchgasser et al. 1988.

Generalized chronostratigraphic chart for Middle–Late Devonian strata of New York (SHB, Sherburne; ITH, Ithaca; CAN, Canandaigua; GEN, Geneseo; BUF, Buffalo; HAM, Hamilton Group). This study focuses on the lower Genesee Group (Givetian) of central New York. The Geneseo Formation marks the onset of the third tectophase of the Acadian Orogeny (Ettensohn 1987), the most pronounced thrust loading event of this orogeny. The Genesee Group onlaps the Taghanic disconformity westward, thus, the ages of the onlapping Geneseo and Penn Yan shales become progressively younger westward (Kirchgasser et al. 1988).

—(A) Lansing Kansas City formation at Geneseo field, central Kansas uplift, J. R. Lansing 5 key well showing unprocessed logs with tabular log analysis. The more widely separated (shaded) intervals have the lowest water and highest oil saturations. Without specific core control, flow units are defined based on log changes, and numbered from the top without respect to quality. Flow units may be typed by pattern recognition on the gameboard crossplots. Favored is 1, 2, and 6 vs. 3, 4, and 5 as two distinct flow unit types on the Pickett and Sw/depth plots. The Buckles suggests even greater complexity. (B) Regional cores from Geneseo field’s Lansing Kansas City limestone taken in a deeper sequence from an older offset well. Variations in moldic dispersion control reservoir performance characteristics. Cementation exponent (m) increases with moldic dispersion.

Conceptual diagram that summarizes the depositional environment, transport mechanisms, and depositional processes of the Geneseo Formation of central New York (NW to SE transect). Fluvial discharge events are shown to transport fine-grained sediment offshore as hyperpycnal flows and hypopycnal plumes. Storm processes are presumed to interact with the seafloor, causing erosion and supply sediment to the distal realm via wave-induced currents and storm setup-relaxation flows. In the distal setting, significantly decreased clastic input and heightened primary productivity in the surface waters results in enrichment of organic matter and development of a shallow redox boundary in the sediment. The chart below the diagram includes interpretations of depositional environment, ecologic stress, as well as bioturbation intensity (solid line represents mean values, gray dashed area represents possible intensities) and diversity.

A) Photomicrograph showing agglutinated benthic foraminifera (yellow arrow) with partial internal fill that prevented complete collapse (plane-polarized light). Foraminifera are eukaryotic organisms, and as such require some oxygen to persist (Schieber 2012). They are very common in the Geneseo Formation, and are distinguished by the fact that they consist of an assemblage of detrital quartz grains typically smaller than 10 µm. A′) The same image in cross-polarized light. The foraminifera consists of tiny gray birefringent quartz grains. B, B′) Scattered benthic fecal pellets in the mudstone matrix (plane and cross-polarized light, rotated 45°). The pellets (yellow arrows) are flattened by compaction, and consist of a mixture of silt and clays that were ingested by sediment-feeding organisms. The presence of benthic life is confirmed by the common presence of benthic fecal pellets and benthic agglutinated foraminifera in these strata.
