Problems in palaeomagnetic synthesis illustrated by results from Permo-Triassic dolerites in Guyana

, : Problems in palaeomagnetic synthesis illustrated by results from Permo-Triassic dolerites in Guyana. Physics of the Earth and Planetary Interiors 16(3): 0-284

Relatively consistent palaeomagnetic results have been obtained after alternating field demagnetization of samples from seven of eight dolerite dykes (ten sites) intruding the basement shield in Guyana. Results from five of these dykes (seven sites, 33 samples) give an average site-pole at 63°S, 138°W, k = 24.6, 95 = 12.4°. Despite KAr ages ranging from 262 to 675 m.y., the good grouping suggests that these dykes are generally contemporaneous, and they are judged to be Permo-Triassic. The remaining two dykes have distinct, apparently Precambrian, magnetizations.

Serum ghrelin concentration decreases rapidly after a meal, probably because of the concurrent increase in serum insulin. An...
