The characterization of crude oils in terms of source rock facies and depositional environment, as well as their maturity and alteration stage, is a crucial element in exploration studies. The present contribution has implications for oil-oil and oil

Hydrological models alone can be ambiguous in the determination of flowpatterns and groundwater ages. Their use is thus somewhat limited in the study of controls and spatial distribution of groundwater compositions. Multilevel wells can be useful for

Regional and national ground-water monitoring networks are used to inventory and to monitor diffusive (nonpoint) sources of ground-water contamination. The Dutch National Ground Water Quality Monitoring Network (LMG) is an example of such a network,

The described RQ-mode factor-analysis program, written in Pascal, is based on a principal-component analysis of the correlation matrix (R-mode). It makes use of the Jacobi-threshold method to determine the eigenvalues and eigenvectors of the correlat

Recently, Vriend et al. (1985) studied the trace element behaviour of the Regoufe granite. The Regoufe granite is situated about 70 km SE of Oporto and belongs to the Hercynian massifs in the north of Portugal. The granite has been studied in detail

Multi-element lithogeochemical surveys of aureoles surrounding tin-tungsten-bearing quartz vein systems have been utilized infrequently in exploring for these deposits. At Panasqueira, Beira Beixa, Portugal, a Wrich quartz vein mineralization occurs
