Geological Magazine (1990) 127 (6): 497-525.
...R. A. Cooper; K. Lindholm Abstract Fourteen early Ordovician (Tremadoc-Llandeilo) graptolite sequences from around the world are precisely (infrazonally) correlated, based on the stratigraphic ranges of 130 species and species groups. The composite standard sequence (CSS) of graptolites has been...

... succession. The correlatable 'features' of the Avalon Peninsula late Precambrian—fossils, tillites, and volcanic episodes, have been correlated with similar 'features' in late Precambrian sequences in other parts of the world where these 'features' have been dated isotopically. Some of the correlations...

.... This paper is a first attempt to build a nearly worldwide correlation of middle and upper Precambrian sediments based on age determinations. The main problem with these results is in their interpretation. The age may be the age of the source area of the sediment, the time of deposition or early diagenesis...

... T. C. Chamberlin’s 1898 diastrophic (tectonic) control paper was a short editorial-like response to a questionnaire about geologic time divisions; the more famous and even shorter 1909 paper restated the primacy of diastrophic control of worldwide unconformities as a basis for correlation...

... concentrations of elements such as Ir, Ni, Co, Cr, Zn, Cu, As, and Sb. At first glance, the global correlation of element enrichments may seem to be strong evidence for a dust-cloud origin of the basal red layers. However, detailed layer-by-layer major-element analyses (e.g., Si, Al, Mg, Ca, K, and Na), together...

Ross Abstract More than fifty transgressive-regressive depositional sequences are present in Carboniferous and Permian shallow marine successions on stable cratonic shelves worldwide. These were synchronous depositional events resulting from eustatic sea-level changes...

... asphaltene chains begin to conglomerate and tangle. In contrast, increased resin content actually decreased viscosity. However, a recent analysis by Hossain et al. (2005) found no strong viscosity correlation with asphaltene content. Because viscosity partly controls our seismic velocities, the influence...
