Loop Head Ross Fm


Loop Head Light House, Co Clare Loop Head seen from the west and photographed by David Pyles from a hellicopter. The Shannon Estuary is to the right or south and the Atlantic to the left or north The Ross Formation on the north east side of Loop Head photographed by David Pyles over the Atlantic in a hellicopter. The rocks are represented by turbidite sheet sands that accumulated as deepwater fan lobes that were dissected by sparse shallowly incised channels. As Elliot (2000) records these are the thicker bedded, high net-to-gross, sheet turbidites of the lower part of the Ross Sandstone Formation turbidite system. The height of these cliffs is between 45-50 m. Note the shaley partings that may compartmentalize these sands and seperate them in terms of their reservoir quality from those above. Channeling may enhance vertical reservoir continuity between the stacked sheets The Ross Formation of Loop Head is here expressed as turbidite sheet sands that accumulated as deepwater fan lobes that were dissected by sparse shallowly incised channels.

Deepwater Loop Head Ross Formation
 
Loop Head - Ross Formation - Deepwater Sand Sheets with Low Relief Channel Incision

Outcrops between Atlantic shore and north side of Shannon Estuary, Co Clare. These cliffs of the Ross formation are approximately 45-50 m. exposing deepwater sheet sand fan lobes with sparse shallow channeling.  Elliot (2000) records how these are the thicker bedded, high net-to-gross, amalgamated sheet turbidites of the lower part of the Ross Sandstone formation turbidite system. shaley partings occur between many of the sands , compartmentalizing these them, separating them in terms of their potential reservoir quality from those above. Channeling may enhance vertical reservoir continuity between the stacked sheets, amalgamating them.  At the Bridges of Ross exposure to the north, the fan lobes pass upward into a wide spread slumped sediment horizon. Note the monocline that dissects the line of cliffs from north to south.
