The Carboniferous Shannon Basin of Western eire has develop into probably the most visited box components on the earth. It offers an excellent chance for interpreting a variety of historic sedimentary environments, together with carbonate shelf, reefs and dirt mounds, black shales and phosphates, and a spectrum of deep sea, shallow marine, fluvio-deltaic and alluvial siliciclastic sediments. the world boasts broad outcrops and a few of the main popular sections via turbidites, large-scale gentle sediment deformation positive aspects and sediments that show a reaction to tectonic and sea-level controls.
This box advisor offers the 1st synthesis of the important localities during this sector of Western eire, and provides an simply available guide that may consultant the reader to, and inside of, quite a lot of sedimentary facies, permitting an realizing of the evolving nature of the fill of this Carboniferous basin and the context of its sedimentary and tectonic evolution. The advisor summarizes contemporary and new paintings within the zone through quite a number authors and descriptions problems with present debate in regards to the Shannon Basin and its palaeoenvironmental interpretation. the sector advisor will locate vast use in instructing and study through educational researchers, expert and novice geologists, in addition to by way of utilized geologists, geophysicists and reservoir engineers who use those outcrops as analogues for subsurface reservoirs in lots of parts of the world.

Distribution of vitrinite reflectance (Rm) in the Doonbeg No. 1 Well (after Clayton & Baily, 1999). Thus, the rocks of the Shannon Trough indicate relatively low levels of tectonic deformation but higher than expected burial temperatures, and there is some evidence that the peak temperatures preceded fold development.
Sometimes forming coalescing, reef‐like mounds, these Waulsortian carbonates lack constructing organisms like normal reefs and instead have a high proportion of cement that infills large‐ stromatactis‐like cavities and fissures (Lees, 1961; Lees & Miller, 1995). The Waulsortian facies of southern Ireland are the most extensive strata of this unusual limestone, and the huge thickness in the Shannon Basin, where it approaches 1200 m thick, is by far the thickest development in the world (Shephard‐Thorn, 1963; Sleeman & Pracht, 1999).
