lithologic การใช้

• These variations provide a lithostratigraphy or lithologic stratigraphy of the rock unit.
• These pools are accumulations of oil in permeable sand lenses within less permeable lithologic units.
• First, the lithologic indicators of seasonality should span broad distances along the Pangean coasts.
• The lithologic characteristics of the unit are different north and south of the Santa Ynez River.
• Under this criterion, crystals of kyanite appear upward of several meters from the lithologic change.
• The Cottonwood Limestone is one of the most persistent and easily recognizable lithologic character across its range.
• Chemostratigraphy studies the changes in the relative proportions of trace elements and isotopes within and between lithologic units.
• They conceived soils as mainly the weathering products of geologic formations, defined by landform and lithologic composition.
• The Sinbad s lithologic make up causes it to weather platy or massive depending on the rock structure.
• The lower boundary of a zone in which plinthite occurs generally is diffuse or gradual, but it may be abrupt at a lithologic discontinuity.
• The Aspiring Lithologic Association schist, south of the Caples Terrane and north of the Alpine Fault, is regarded as belonging to the Rakaia Terrane.
• Named by Lupton ( 1916 ), the formation is readily divisible into upper and lower members on the basis of both lithologic character and depositional history.
• Changes in currents or physical deformation in the environment can be determined upon observation and monitoring of a depositional surface or lithologic sequence with unconformities above or below a graded bed.
• Planned products include digital-format shale-oil analyses, stratigraphic and lithologic information, geophysical logs, bibliographic references, and geologic maps of oil shale lands in the western United States.
• Most Archean volcanic and granitic rocks are strikingly different in bulk compositions and occurrences from Phanerozoic ones ( 0.54-0 b . y . ago ), even those that bear the same broad lithologic names.
• The FGS maintains several geological databases that are available through its website including a lithologic database, subsidence incident reports database, University of Florida / FGS vertebrate and invertebrate paleontology collections, and various geological and hydrogeological GIS coverages.
• By lithologic criteria, the Main Central Thrust is defined as the boundary between quartzite and phyllite, from the Lesser Himalayan Sequence; and the orthogneiss biotite-rich schist, which belongs to the Greater Himalayan Crystalline complex.
• Sedimentary models of such fan systems typically are subdivided into upper, mid, and lower fan sequences each with distinct sand-body geometries, sediment distributions, and lithologic characteristics ( Mutti & Ricci Lucci, 1975; Normark, 1978; & Walker, 1978 ).
• Three lithologic types are identified : ( 1 ) syenite, found most abundant on the west side of the playa; ( 2 ) dolomite, subrounded blue-gray stones with white bands; and ( 3 ) black dolomite, the most common type, found almost always in angular joint blocks or slivers.
