Among the numerous models that have been suggested for the primary and predominant source of silica for chert, we suggest that eolian dust is worthy of further considerations. Such considerations are supported by the common association of Phanerozoic

Melanterite (FeSO4·7H2O)-rozenite (FeSO4·4H2O) and chalcanthite (CuSO4·5H2O)-bonattite (CuSO4·3H2O) equilibria were determined by humidity measurements at 0.1 MPa. Two methods were used; one is the gas-flow-cell method (between 21 and 98 °C), an

The Gibbs free energy of formation of nukundamite (Cu 3.38 Fe 0.62 S 4 ) was calculated from published experimental studies of the reaction 3.25 Cu 3.38 Fe 0.62 S 4 + S 2 = 11 CuS + 2 FeS 2 in order to correct an erroneous expression in the published

The heat capacities of synthetic coesite and jadeite were measured between about 15 and 850 K by adiabatic and differential scanning calorimetry. The experimental data were smoothed and estimates were made of heat capacities to 1800 K. The following

The heat capacities of five mineral samples from the scapolite solid-solution series, Na 1 Al 3 Si 9 O 24 Cl (marialite) to Ca 4 Al 6 Si 6 O 24 CO 3 (meionite), were measured by the adiabatic method from T = 8 K to T = 350 K and by the differential s

The heat capacity of synthetic Cu3AsS4(enargite) was measured by quasi-adiabatic calorimetry from the temperatures 5 K to 355 K and by differential scanning calorimetry fromT= 339 K toT= 720 K. Heat-capacity anomalies were observed atT= (58.5 ± 0.5)

The heat capacity of sodalite was measured with a computerized adiabatic calorimetric system at temperatures from 15 K to 350 K and with a d.s.c. from 340 K to 1000 K. No anomalies were observed over the entire range except for a peak atT≈250 K ass

Heat-capacity measurements were made on deerite and on grunerite with an adiabatic calorimetric system from the temperature 10 K to 350 K and by d.s.c. in the super-ambient region. Slight Schottky-like and bell-shaped anomalies appear near T =16 K an
