.... This variety of quartz also possesses a higher albedo in hand sample than colorless examples. Despite the intense coloration, no compositional origin for the browning is evident. A high proportion of exceptionally small (typically submicron scale) fluid inclusions, which are typically too small to be observed...

...Olav Walderhaug; Johannes Rykkje Abstract Study of metamorphic and igneous rocks from onshore and offshore Norway shows that quartz cathodoluminescence (CL) colors are not uniform in the examined lithologies. Neighboring quartz crystals in thin sections from granites and granodiorites may vary...

... gradients in the surrounding sedimentary rocks. These gradients were partitioned by preexisting faults in the sedimentary rocks creating cells of fluid circulation. Assemblages of agglutinated foraminifera reported from North America have shown color gradients, which are interpreted as being related...

..., the bioturbated zone may be preserved almost intact; the benthic food content in such frozen tiers can be interpreted from the ethology, size, penetration depth, and density of trace fossils. Especially high benthic food content is characterized by (1) dark sediment color, (2) complete bioturbation, (3) high...
