The Larsen Harbour Formation of southern South Georgia is part of an ophiolite sequence of submarine lavas and sheeted dykes emplaced into metasedimentary country rocks. The metasediments are remnants of […]
An analysis is made of the disturbance in conductive heat flow caused by drilling a bore hole in ice in which there is a vertical temperature gradient. The model used […]
The growth of two Antarctic lamellibranchs, Adamussium colbecki (E.A. Smith) and Laternula elliptica (King and Broderip), has been investigated. A. colbecki is a pectinid that grows to a shell height […]
O’HARA1 has recently proposed an open-system model for the fractional crystallisation of magmas involving continual replenishment of the magma chamber and only partial extraction of the fractionated liquid at each […]
Following current interpretation of isotope data from oceanic basalts, the case for inheritance of Rb/Sr and 87Sr/86Sr ratios in continental igneous rocks from long-lived heterogeneities in the mantle is reviewed, […]
Following a shift from autotrophic to heterotrophic nutrition, cells of Chlorella protothecoides become sensitive to the stresses of freezing and thawing. The injury then observed at slow rates of cooling […]
