Carbonate platform evolution and conodont stratigraphy during the middle Silurian
Mulde Event, Gotland, Sweden.
Radiometric dating of a granodiorite at the Cuttaburra A prospect indicates that this mineralised system may be Middle Silurian
in age and thus indicating that the host rocks are older than those hosting the Cobar-type deposits.
This contact is that between Middle Silurian
carbonates (Peebles Dolomite, Tymochtee Formation, and Greenfield Dolomite and the fissile brown and black shales of the Upper Devonian Olentangy and Ohio Shales.
A stratigraphic and sedimentologic analysis of some Lower and Middle Silurian
clastic rocks of the north-central Appalachians.
2000) have identified large peaks in the distribution of dolostones during the last 570 Ma, namely in the Early Ordovician Middle Silurian
The maximum age is constrained by the occurrence of middle Silurian
fauna; a minimum age limit is not tightly constrained.
The Middle Silurian
is represented by the Burnt Bluff Group, which is composed of light gray, calcitic dolomite and limestone, and the Manistique Group, which consists of brown or gray, cherty dolomite that contains beds of lime mudstone.
Indiana"), has been drilled to a depth of approximately 4,840 meters, which is the lower portion of the Middle Silurian
Figures 1a and 1b show examples of shatter cones in the Lower Silurian Brassfield Limestone and Middle Silurian
Lilley Formation respectively.
Early and middle Silurian
conodonts from midwestern New South Wales.
Thomka & Brett (2014) argued that matrix-supported reefs are not observed at every major middle Silurian
transgressive surface and inferred that additional control was necessary to explain time-specific reef facies appearing specifically during Silurian carbon isotope excursions.
This Middle Silurian
age for the granitic intrusion found at the Cuttaburra A prospect rules out a Cobar-type model (which is younger - Early Devonian) for the gold mineralisation, if it is associated with the granite as it appears to be.
