Ochiai, 1983) 76) A weltknown example of the younger period is the cupriferous Nonesuch shale deposit at White Pine, Michigan. Liquid oil was found there trapped as primary fluid inclusions in calcite crystals which are dated at about 1050 MY. According to the observations the organic materials must have played a significant role in controlling the copper mineralization of the sediment (Kelly & Nishioka, 1985) 7s). Analyses show that the oil contains the full spectrum of hydrocarbons typical of unbiodegraded crude oil.

6, p. 10). It is actually impossible to establish any clear-cut morphological difference between the Gunflint-Huronispores (commonly interpreted as cyanobaeteria) and wellpreserved Isuaspheres. The structures display similar morphological and mineralogical features indicating that they are both of the same origin and the product of similar, degradational and diagenetic processes. The only notable difference is that the Isuaspheres have been subjected to a more intense metamorphism. In weathered samples of the Isua quartzite, most carbonaceous material has been leached out along with the associated carbonates, leaving spherical cavities in the place of the Isuaspheres.
