摘要:

Electrical resistivity surveying has not been widely applied in British Quaternary studies. The results of one such survey, undertaken to assess the value of this technique, are described, and they suggest that, in certain circumstances, this method may offer considerable advantages over more traditional surveying methods.

摘要:

Pyrites from Swedish base metal sulphide ores show trace element patterns characteristic for some types of ore. The indicative elements are Co and As. The use of these trace element patterns is proposed as a possible method for prospecting.

摘要:

Geochemical studies indicate that the Early Proterozoic leptite formation of metavolcanics is comagmatic with the primorogenic I-type granites. Both rock units show an evolution consistent with the one predicted by increased maturity of a continental arc. The serorogenic S-type granites and the postorogenic I-type granites (Dala type) form minor intrusions. The main episode of plutonic activity is terminated by the postorogenic S-type granites of the Småland-Värmland belt. The geology of central and south-eastern Sweden is seen as two major granitoid belts trending N-S, with I-type (primorogenic) granites to the east and S-type (Småland-Värmland) granites to the west, resembling the geology of modern continental arcs, e.g. the western Americas.

摘要:

Seventy-four soil profiles in old spruce, beech and oak stands at Tönnersjöheden Experimental Forest were sampled both in 1927 and 1982–83. Each new profile was located within about one metre of the sampling point from 1927. Samples were collected from the A0, A2, B and C horizons down to a depth of 70 cm in mineral soil. Both in 1927 and 1982–83, pH in the soil samples was measured potentiometrically (quinhydrone electrode). The new pH-measurements were also made with a glass electrode. Today, lower pH-values were obtained in all sampled soil horizons compared with 1927. The decline in pH is 0.3–0.9 units in the humus layer and 0.3–0.7 units in the mineral soil.
