The Cambeck Member is part of the [[Lyne Formation]].<br />
=== Name ===<br />
Previously known as the Cambeck Beds (Day, 1970)<ref name="day70">Day, J B W. 1970. Geology of the country around Bewcastle.''Memoir of the Geological Survey of Great Britain'', Sheet 12 (England and Wales).</ref>. See also Leeder (1974)<ref name="leeder74">Leeder, M R. 1974. Lower Border Group (Tournaisian) fluviodeltaic sedimentation and palaeogeography of the Northumberland Basin.''Proceedings of the Yorkshire Geological Society'', Vol. 40, 129–180.</ref>.<br />
<br />
=== Lithology ===<br />
Rhythmic cycles of mainly sandstones, thin limestones and mudstones (the beds being abundantly shelly), and some algal beds and subsidiary siltstone. See Day (1970)<ref name="day70" />; Leeder (1974)<ref name="leeder74" />.<br />
<br />
=== Stratotype ===<br />
Partial type sections at Bewcastle include the River White Lyne (NY 5116 7300 to 5109 7322) with strata from the Lower ''Antiquatonia'' Band to the base of the Whitberry Band, and Whitberry Burn (NY 5220 7404 to 5203 7408) with strata from the Barrow’s Pike Sandstone to the base of the Whitberry Band (Day, 1970)<ref name="day70" />.<br />
<br />
=== Lower and upper boundaries ===<br />
At Bewcastle, the base is conformable on the uppermost algal bed (M.A.14 of Day, 1970)<ref name="day70" /> of the [[Main Algal Member]] (Figure 11, Column 2), which comprises rhythmic alternations of limestone and mudstone with nodular algal beds.<br />
<br />
There is a conformable upper boundary with the base of the locally developed Whitberry Band of the sandstone-dominated [[Fell Sandstone Formation]].<br />
<br />
=== Thickness ===<br />
204 m at Bewcastle.<br />
<br />
=== Distribution and regional correlation ===<br />
The Northumberland–Solway Basin, but described only in the Bewcastle region (Day, 1970)<ref name="day70" />.<br />
<br />
