Increasing amounts of data is collected in most areas of research and application. The degree to which this data can be accessed, analyzed, and retrieved, is a decisive in obtaining progress in fields such as scientific research or industrial production. We present a novel methodology supporting content-based retrieval and exploratory search in repositories of multivariate research data. In particular, our methods are able to describe two-dimensional functional dependencies in research data, e.g. the relationship between ination and unemployment in economics. Our basic idea is to use feature vectors based on the goodness-of-fit of a set of regression models to describe the data mathematically. We denote this approach Regressional Features and use it for content-based search and, since our approach motivates an intuitive definition of interestingness, for exploring the most interesting data. We apply our method on considerable real-world research datasets, showing the usefulness of our approach for user-centered access to research data in a Digital Library system.

Gold in Ophiolites

Ophiolites, as a class, have been currently under-estimated as potential gold targets, although they have been the subject of major scientific research. Their resources have also attracted investors producing Cr, Cu (massive sulphides), Co, Ni (laterites), industrial rocks and minerals (serpentinites, emeralds), etc. They are also potential PGE sources.
