Criteria for evaluation of potential field interpretations
By D.E. LeamanAlthough the potential field methods have well established theory, acquisition technology and interpretation procedures, they have a poor reputation in many quarters. Many companies and workers refuse to use the methods or accept any results, often due to previous bad experiences or a belief that ambiguity is inevitable and resolution poor. Even sympathetic users have encountered problems with interpretations. The lack, or apparent lack, of rigour in interpretation methods and the possible multiplicity of solutions deters many users, even though the methods are capable of providing cost-effective coverage of surveyareas.

Maturity and burial history of the Kimmeridge Clay Formation, onshore UK: a biomarker study
More LessPrevious studies on the maturity of the Upper Jurassic Kimmeridge Clay Formation (KCF) from onshore UK have reported maturity ranging from very immature to near oil-window levels (Scotchman 1987b and references therein). Maturity determination based on geochemical parameters measured on bulk kerogens, such as vitrinite reflectance (VR), Rock-Eval pyrolysis and element al analysis (EA), have been demonstrated to be strongly dependent on organic facies (Scotchman 1991a) and, by inference, sedimentation rate and depositional setting (Scotchman 1989, 1991a).

An aeromagnetic compilation over mainland Norway
Authors M.A. Smethurst, O. Olesen and H. HåbrekkeData from over 20 years of diverse aeromagnetic surveys in Norway have been compiled into a single grid by the Geological Survey of Norway (NGU). Taken together, the surveys comprise 500000 line-krn, covering approximately 400000 krrr', 324000 km2 of which are over land. The compilation is the first to offer a comprehensive picture of magnetic anomalies over mainland Norway.

Cretaceous subsidence and inversion along the Tornquist Zone from Kattegat to the Egersund Basin
Authors T.E. Mogensen and L.N. JensenThe Tornquist Zone from the Baltic Sea to the Egersund Basin (Fig. 1) has been studied by several workers, who have made use of field information, well data, and deep reflection and refraction seismic data as well as commercial seismic reflection data (Baartman and Christensen 1975; Pegrum 1984; Symposium on Tornquist Zone geology 1984; Liboriussen et al. 1987; Ziegier 1987; Aubert 1988; Eugeno-S Working Group 1988; Ro et al. 1990; Michelsen and Nielsen 1991; Jensen and Schmidt 1992; Mogensen and Korstgard 1992; Mogensen 1992).
