McFarlane, 1976, 1983a), through to mineralogical and textural based schemes (e.g. Aleva, 1986 Bardossy and Aleva, 1990), to a system incorporated within soil taxonomy (Soil Survey Staff, 1975), as well as more quantitative, chemically based genetic classifications (Schellmann, 1982). It is not the intention of this chapter to discuss the merits of these schemes, nor to outline the others that have been proposed this has been reviewed previously (e.g. McFarlane, 1976, 1983a Aleva, 1994 Bourman and Ollier, 2002). Instead, a simple distinction is made between laterite and ferricrete (Aleva, 1994), and a chemical classification for defining lateritic materials (Schellmann, 1982, 1986) is adopted.

The Brazeau River Cardium oil is regarded as Cretaceous. The Pembina Cardium oil, in a field contiguous to the northeast, is assigned to a Cretaceous source, the Second White Speckled Shale, in the genetic classification of Li et al. (2001). Several oil accumulations occur in the... 

Each of these schemes has both merits and limitations. Problems arise where different schemes use similar or identical labels. As mentioned above, the label authigenic is sometimes used for the acid-extractable fraction. The danger is that this brings with it concepts associated with its definition under the genetic classification scheme.

Useful also is a genetic classification of minerals in coal, wherein they are classified as (1) detrital, (2) syngenetic, or (3) epigenetic. 

Vein-like deposits were described as uranium deposits of uncertain genesis by Mathews etal Except for a small number of these deposits in sedimentary rocks, the group is subdivided into unconformity-related deposits and deposits of metamorphic rocks. In a more genetic classification of the major (Proterozoic) vein-like deposits of the world, Dahlkamp and Adams deciphered the relationship of diagcncsis, metamorphism, metasomatism and weathering on uranium concentrations in various host rocks. The result is a logical genetic explanation for the spectrum of vein-like deposits observed today.

If the diagnosis of AS is suspected in a patient, a mutation screening in the responsible collagen genes as a basis for genetic classification and counseling has to be discussed. In patients with a proven mutation, no invasive diagnostic means, such as renal biopsy, are necessary.
