Use thinsections as back up. [Pattern number below pattern box; generic lookup-table symbol number in upper left-hand corner of pattern box] EXPLANATION Pattern number shown below box. The different lithologic environments encountered during Leg 175 enable us to evaluate the reflectance pattern of specific wavelengths in the visible band for each lithologic type and to compare the color data with preliminary shipboard measurements of calcium carbonate and organic carbon contents and magnetic susceptibility. Formation: fundamental lithologic stratigraphic unit a. lithologically distinctive rock unit that is at a mappable scale at the surface and/or traceable into the subsurface b. 0000038300 00000 n Some subsequent delineation wells are likely to be cored over the entire of the reservoir interval.

In certain situations, a symbol or its usage might need to be modified in order to better represent a particular feature on a geologic map or cross section. Jon F. Kaminsky .
