At the Matauri Bay halloysite deposit, economically valuable halloysite-rich clays are hosted by a sanidine rhyolite dome (Ar–Ar dated at 10.1 ± 0.03 Ma). The rhyolite dome intrudes an older basalt and is overlain by alluvial sediments and a young

Warfarin resistance in the brown rat is known to be associated with deficient vitamin K metabolism and reduced viability, especially in young males. We investigated the possibility that warfarin resistance may impose another fitness cost by reducing

SUMMARY Wheat was treated with 14C-warfarin sodium (0–02%, w/v. a.i.) using the recommended method for preparing bait for the control of grey squirrels (Sciurus carolinesis L.). The persistence of this anticoagulant on sterilised grain was determin

Mossbauer spectra of nontronite, glauconite and montmorillonite recorded at temperatures down to 1.3 K and in applied fields of up to 4.5 T confirm that nontronite and glauconite are antiferromagnetic at 1.3 K. Glauconite becomes ferromagnetic in app

Mossbauer spectra of glauconite and nontronite recorded at temperatures down to 1.3K and in applied fields up to 4.5 T show that Fe III spin configurations are respectively ferromagnetic and antiferromagnetic. It is shown that in a particular materia

Mossbauer spectra of biotite at 4 K are reported. The biotite crystals were oriented with the c-axis parallel to the γ-ray direction and some spectra were recorded with external magnetic fields of 40 kOe applied at right angles to the c-axis.
