“…The mineralization is preferentially enriched immediately below siltstone and shale bands as well as in dolomitization voids and fracture systems. The thickness and distribution of the stratiform ore is related to the paleotopographic control of knolls of Waulsortian micrites (S. Taylor, 1984). Navan represents a different style of mineralization in that the orebody consists of five vertically superimposed stratiform lenses with cross-cutting veins and breccia zones within Lower Carboniferous limestones (Andrew & Ashton, 1985;.…”

“…In the upper stratiform ores at Silvermines Ag is directly proportional to Pb due to inclusions of boulangerite and jordanite in galena (S. Taylor & Andrew, 1978). In addition, an isolated lens of rich silver mineralization in barite contains prominent patches of discrete silver minerals such as proustite, xanthoconite, smithite, miargyrite, argentite-acanthite, and argyrodite as well as gersdorffite (S. Taylor, 1984). The lateral zonation at Silvermines and Tynagh is Cu-Pb-Zn-Mn with Mn forming an extensive aureole of up to 7 km in the carbonates at Tynagh (Russell, 1978).…”

“…La texture framboïdale a été rapportée et documentée comme une texture primaire de mise en place et sa conservation est due à l'arrangement des microcristallites, à sa taille et à son environnement de formation (Chauhan 1974;Ferguson et al 1974;Massaad 1974;Larter et al 1981;Leitch 1981;Taylor 1982;Taylor 1984;Roberts 1980). La texture framboïdale est définie comme un agrégat de microcristallites (20 à plus de 300) ordonnés ou non.…”

“…Many Pb-Zn-Ag deposits of Ireland, including Tynagh, Silvermines, and Keel, that were once thought to be sedex or early diagenetic in origin are now considered to have formed in a diagenetic to epigenetic setting (Taylor, 1984;Briskey, 1986;Samson and Russell, 1987;Ashton and others, 1992;Ritzman and others, 1992). Russell and others (1982) proposed a sedex origin for the Irish deposits, while others, such as Hutchinson (1983), suggested that the ores were actually epigenetic.…”
