Description 
Seaham Quarry is a small, disused shale quarry at Seaham, 14 kilometres northwest of Raymond Terrace. The quarry walls are north facing and one to two metres high. In 1925 a signboard was erected by Edgeworth David proclaiming the area is to be "preserved in perpetuity".

The varved sediments in the Seaham Quarry belong to the Upper Carboniferous Seaham Formation, equivalent to the Main Glacial Beds of Osborne (1922). In the Seaham area the formation consists of 600mm of tillite, varved shale, aqueo-glacial conglomerate, tuffaceous sandstone, and mudstone. Osborne (1925) recognised three tillite and three varved shale horizons, of which that exposed in the quarry is the lower-most and thickest.

Crowell and Frakes (1971, p. 137) described the appearance of the strata in the quarry as follows: "Laminated clay-shale layers, from 5 mm to 10 cm are separated by thinner fine-sandstone layers, from a few millimetres to a centimetre in thickness. Many thin sandstone units are graded, and locally display starved ripples with shapes and internal cross-laminations indicating the sense of current transport. Scattered through the section are rounded pebbles up to 6 cm in diameter...which occur within thicker mudstone layers as well as on bedding planes demarcated by graded sandstones".

Occasional pockets of such pebbles were observed by Sussmilch. Glaessner (1957) described and illustrated a new species of arthropod trace fossil, Isododichnus osbornei, from varve shales at Seaham. The exact locality is not stated but the specimens were most likely collected from the quarry where they had previously been recorded as annelid tracks. The probable depositional environment of the quarry strata, as envisaged by Rattigan (1967) and other workers, was a shallow periglacial lake
