57Fe M�ssbauer measurements have been used to determine the iron phases resulting from weathering of arsenopyrite ore from an abandoned gold mine stockpile. The principal product is the basic ferric arsenate, pharmacosiderite, with smaller amounts of scorodite, ferrihydrite and goethite and some untransformed pyrite and clay ...

Fuel-scale and time-scaled heater experiments are underway in a large granite rock mass adjacent to an abandoned iron-ore mine at Stripa, Sweden. Predicted and measured temperature fields over the past several months are in excellent agreement for both series, but discontinuities are affecting the mechanical behavior. Fracture hydrology is also being ...

Laboratory ultrasonic velocity measurements were made on quartz monzonite drill core specimens taken from an abandoned iron ore mine in Sweden. Measurements were taken on oven-dried samples and at various moisture levels up to full saturation. The results show that small increases in moisture content can substantially increase V/sub p/ ...
