摘要:

In order to clarify the reason behind the peculiar odor of the rock, organic constituents from a Precambrian (∼ 2.0 Ga) tremolite skarn from Posio, northern Finland, were studied using X-ray fluorescence, gas chromatographic, mass spectrometric and amino acid analyzing techniques. Results show the presence of a considerable number of compounds such as PO43-, SH-, NH3, alkanes, alkenes, phtalates, purine, organic silicon compounds, aromatic benzene derivatives, HCN, H2S, acctonitrile, cyanamide, guanidine, isonitriles and some ethylated compounds. The indigenous, adventitious or contaminational origin of the compounds is discussed.
