The quarry in Newbars Wood exposes pebbly sandstones, sandstones and siltstone (10m) of the Ardingly Sandstone Member of the upper Lower Tunbridge Wells Sand Formation (upper Hastings Bed Group). Over a lateral distance of 120m, a wealth of sedimentary structures give evidence of flow conditions and directions (channel-in-channel forms, cross-bedding, texture, etc), while other erosion surfaces, intraformational conglomerates, contemporary ironpan and upstanding Lycopodites record events in a bigger braid-channel, subject to widely varying and episodic flow and exposure.

The A21 - Blackhurst Lane cutting exposes a 6.5m stack of two planar cross-bedded (transverse bar) sandstones, each capped by thin cross-bedded (megatipple) sandstones. The two sequences are separated by a persistent clay seam and the lower is crowded with upstanding Lycopodites (1m) in life-position.

The quarry and road cutting sediments are postulated as having been deposited within a yet larger through-channel traversing the Lower Tunbridge Wells braidplain, of which the quarry in Robingate Wood may expose the 'normal' succession. The three sequences are to be contrasted with those at the Hastings-Pett Level sites, which formed in a more coastal meanderplain.

The sites are vitally important for interpreting conditions in the proximal (northern) area of the Hastings Group basin.
