However K-Ar and Rb-Sr dating as well as biostratigraphic control suggests that the magmatism may have begun at ca. a) A map of Bouguer Gravity, (b) Well studies of 102, 157, 367, 403, 427, 540, 565, 615, 717, and 786, (c) A proprietary gravity survey over the prospect, (d) Geologic mapping of select outcrops in and bordering the area of mutual interest, Biostratigraphic sample collection, (e) Paleontologist analysis, (f) Map production relating to the play, (g) Two structural cross sections with accompanying gravity models, and (h) Between 1600 and 1800 attitudes covering the prospect. Veizer points out that on geological time scales the broad covariance of the different seawater isotopes points to an inter-related lithospere-hydrosphere-atmosphere-biosphere system that is driven by tectonics, and that the major use of seawater isotope trends is as tracers of large-scale features of global evolution and the correlation of sedimentary sequences that have poor biostratigraphic control. |
