For certain geologic-atmospheric interface environments, spectral photometric and photographic techniques are useful in three ways: first, to delineate lithologic units; second, to determine lithologic characteristics; and third, to provide information of the present environment. Investigations were conducted at two sites in the Minas Basin of Nova Scotia where variegated beds of the Triassic Wolfville and Blomidon formations are exposed. Laboratory spectrophotometric measurements, field photometric data, and narrow band photography of the sedimentary units demonstrate an increase, in the visible spectrum, of reflectivity with increase in wavelength of the incident radiant energy. Inorganic encrustations substantially alter the spectral characteristics of sedimentary units in situ. (Author).
